Quick Take: Charging with the Monoprice 80W USB-C/USB-A wall charger

[Update below from Monoprice on the USB-A ratings.]

I recently bought the Monoprice 33467 wall charger, and got a question about charging wattage on the site a little while afterward. Since Monoprice does not provide specific rates for the ports on this device, other than 60 watts on USB-C (standard for USB Power Delivery chargers) and 80 watts total, I decided to get out some thirsty high-draw devices and USB power meters to see what the rates would be.

Testing kit

This device has a removable two-pin power cable, a USB-C port, and four USB-A ports. The USB-C port is rated for up to 60 watts with USB-PD, and the total adapter is rated for 80W.

Update: The vendor confirms 2.4A per USB-A port, with full capacity available across all four ports simultaneously. See end of post for more.

It gets a bit warm when you load it up, so I wouldn’t put it on a container of ice cream or on bare skin, but it’s not too hot for an 80 watt device.

These are bidirectional-capable testers that show voltage, amperage, milliamps of current, and direction of power. I believe these are identical devices, either licensed or flattered by one or the other vendor. I bought the Satechi almost two years ago, and wrote about it here); the Plugable came out afterward, I believe.

Satechi told me some time ago that they should handle 300W of power, and I’ve used theirs with the 130W proprietary Dell Thunderbolt 3 Docking Station charging option for the XPS 15 9550 laptops, without releasing any smoke.

The bidirectional feature is interesting, in that  you can use some USB-C mobile phones to charge other devices, and this will tell you which way the power is going. It’s also conceivable that you could charge a USB-C power bank with your laptop, as opposed to the other way around.

This is a formidable device in that it supports USB-A, USB-C, and Micro-USB input, with USB-A and USB-C output based on the input source. It’s rated for up to 30V/5.1A which should cover any USB-C charging I’ve seen.

It is large and not friendly to being plugged in next to another cable, as you can see from the picture, but it’s very convenient (even showing four wire voltage and three different English interfaces/displays as well as Chinese). It is not bidirectional, so you’ll plug the metal plug into the power source and your charging cable into the jack.

PortaPow is a UK company that came to my knowledge for their charge-only / data blocker cables. These cables block/bridge the data lines in a USB charging cable, letting you charge (potentially) faster while keeping a host or charging device from spuriously accessing the data on your device.

Their power meters offer similar functionality along with a backlit LED power display. The pictured/linked one is their third version; I’ve used the first two versions successfully, although the older ones do not to my knowledge support higher than 5V charging.

Charging targets:

All targets were chosen for capability to charge at higher than 10W rates, as well as being under half charge so that full charging rate would be realized.

  • Pixel 2 XL from Google, at around 20% charge (USB-C)
  • iPhone 8 Plus from Apple, at under 20% charge (Lightning)
  • iPad Pro 10.5 from Apple, at about 45% charge (Lightning)
  • PowerCore 26800 Premium Portable Charger from Anker, at about 20% charge (Micro-USB)
  • XPS 13 9370 from Dell, at about 40% charge (USB-C PD)
  • XPS 15 9550 from Dell, at about 4% charge (USB-C PD)

Quick and dirty test results

The Pixel 2 XL charged at 12 watts (9.33 volts) with a USB-C cable. With a USB-A to USB-C cable, I got closer to 5 watts, although the cable might be to blame.

The iPad Pro charged at about 12 watts (5.12 volts) with a USB-A to Lightning cable, and about 28 watts with the USB-C to Lightning cable.

The iPhone 8 Plus charged at about 18 watts (9.37 volts) with USB-C to Lightning, but only 8 watts with USB-C to Lightning.

The Anker battery pack charged at about 17 watts (9.34 volts) which is fair for the Quick Charge 2.0 level of input (the newer version of the pack supports QC 3.0, and the Power Delivery version of course supports USB Power Delivery at up to 27 watts input).

The XPS 13 9370 negotiated to 30 watts of input (at 20V profile) while powered down.

The XPS 15 9550 negotiated to 45 watts of input (also at 20V profile) while powered down. This would have reported a BIOS adapter error if I had booted up while connected, as would the Pixel C 60 watt charger, but it will still charge.

Where do we go from here?

In short, if you need to charge several devices at a time, but don’t want 4-5 chargers, the Monoprice 80 watt charger is probably a good choice. If you have a more power-hungry device, like a large MacBook Pro or a heavy USB-C battery pack, you may still want to keep an 87 watt charger around for it, but for modest / travel use, the power this device offers should be good enough to keep you going.

I will probably plug the charger itself into an AC power meter, and see how it handles multiple inputs (including the laptops) in parallel. My expectation is that USB-C would take priority, so with 45W going to USB PD, I could use up to 35W max on the USB-A ports. I did have the iPad, Pixel XL, and Anker battery plugged in at the same time and they seemed to have similar charge rates to each one individually connected.

Have you had experience with the Monoprice charger, or have any test conditions you wonder about? Share in the comments, and I’ll check them out if I can.

[This was intended to be a Quick Take post, and while it was created quickly, it’s not as short as I’d originally planned.]

Update: A Monoprice product specialist responded to my inquiry this morning (11/9/2018). They said that the charger “can supply at least 2.4 amps each port and all four can supply this current simultaneously. The total wattage of 48 Watts across all USB-A ports.” Based on this reading, if you are pulling 12 watts per port, you should be able to drive 32 watts of USB-C which should cover an XPS 13 or smaller, a battery pack, or the newer Apple devices with rapid charging.

Looking back on InteropITX 2017 – the good, the bad, and the future

My fifth Interop conference is in the books now. Let’s take a look back and see how it turned out, and where I think it will go next year. See disclosures at the end if you’re into that sort of thing.

Ch-ch-ch-changes…

The event scaled down this year, moving down the strip to the MGM Grand Conference Center after several years at Mandalay Bay. With the introduction of a 30-member advisory board from industry and community to support the content tracks, Interop moved toward a stronger content focus than I’d perceived in past events.

The metrics provided by Meghan Reilly (Interop general manager) and Susan Fogarty (head of content) showed some interesting dynamics in this year’s attendance.

The most represented companies had 6-7 attendees each, as I recall from the opening callouts, with an average of about 2 people per company. More than half of the attendees were experiencing Interop for the first time, and nearly two thirds were management as opposed to practitioners.

The focus on IT leadership, from the keynotes to the leadership and professional development track for sessions, was definitely front and center.

How about that content?

Keynotes brought some of the big names and interesting stories to InteropITX. There wasn’t always a direct correlation, but there was some interesting context to be experienced, from Cisco’s Susie Wee talking about code and programmability in an application world (and getting the audience to do live API calls from their phones), to Kevin Mandia of Fireeye talking about real world security postures and threat landscapes. Andrew McAfee brought the acronym of the year to the stage, noting that often the decisions in companies are not made by the right person, but the HiPPOs — Highest Paid Person’s Opinion.

With five active tracks, there was content for everyone in the breakouts this year as well. Some tracks will need larger rooms next year (like the Packet Pushers Future Of Networking, which seemed to demand software-defined seating when I tried to get in) and others may need some heavier recruiting.

Attendees can access the presentations they missed (check your Interop emails), and some presentations may have been posted separately by the presenters (i.e. to Slideshare or their own web properties) for general access. Alas, or perhaps luckily, the sessions were not recorded, so if you haven’t heard Stephen Foskett’s storage joke, you’ll have to find him in person to experience it.

Panic at the Expo?

But the traditional draw of Interop, its expo floor (now called the Business Hall), was still noteworthy. With over a hundred exhibitors, from large IT organizations like VMware to startups and niche suppliers, you could see almost anything there (except wireless technology, as @wirelessnerd will tell you about here). American Express OPEN was even there again as well, and while they couldn’t help with fixing Amex’s limited retort to Chase Sapphire Reserve (read more about that on rsts11travel if you like), they were there to help business owners get charge card applications and swag processed.

The mega-theatre booths of past years were gone, and this year’s largest booths were 30×30 for VMware and Cylance among others.

Some of the big infrastructure names were scaled way back (like Cisco, with a 10×10 along with a Viptela 10×10 and a Meraki presence at the NBASET Alliance booth) or absent (like Dell, whose only presence was in an OEM appliance reference, and HPE, who seem to have been completely absent).

These two noteworthy changes to the expo scene were probably good for the ecosystem as a whole, with a caveat. With a more leveled playing field in terms of scale and scope, a wider range of exhibitors were able to get noticed, and it seemed that the booth theatre model and the predatory scanner tactics were mostly sidelined in favor of paying attention to people who were genuinely interested.

The caveat, and a definite downside to the loss of the big names, was that Interop was one of the last shows that gave you a chance to see what the “Monsters of IT Infrastructure” were doing, side by side, in a relatively neutral environment. For this year at least, VMworld is probably as close as you will get to the big picture.

Some of this may have to do with the conference ecosystem itself; Dell EMC World was the previous week in Las Vegas, with HPE Discover the first full week of June and Cisco Live US the last full week of June. These events often occupy speakers and exhibition staffs for weeks if not months beforehand, and the big players also had events like Strata Hadoop World in London to cope with as well. (See Stephen Foskett’s Enterprise IT Calendar for a sense of the schedule.)

Will the “Monsters of IT” come back next year?

I’d like to see them return, as fresh interest and opportunity is a good way to sustain growth, but I have a feeling that focusing on their owned-and-operated events and away from the few (one?) remaining general IT infrastructure event is likely to continue. They may just field speakers for the content tracks and assume that people will come to them anyway.

Meanwhile,  smaller players will continue to grow. While they appear to just be nipping at the heels of the big players, they’re building a base and a reputation in the community, and they don’t need to beat the Cisco/Dell/HPE scale vendors to succeed. So maybe everyone wins.

But what about InteropNet?

The earliest memory I have of Interop, from my 2013 visit, was finding a pair of Nortel Passport (nee Avaya ERS) 8600 routing switches in the InteropNet network. InteropNet has been a demonstration platform that brought together a wide range of vendors including routing and switching, wireless, and software layers (monitoring and management in particular), and it was noticeably absent this year as well.

Part of this may be due to the smaller size of the Business Hall, but part is also due to the cost (time and money at least) of setting up and operating the multivendor environment. The absence of most of the enterprise network hardware vendors may also have played into it, although I don’t know if that was a cause or an effect. As fascinating as Extremo the Monkey was, I don’t think an all-Extreme Networks InteropNet would have really demonstrated interoperability that well.

I didn’t talk to any of the network vendors who weren’t there, but some of the software layer vendors were unabashedly disappointed by the loss of InteropNet. It’s one thing to show a video recording or demo over VPN back to a lab somewhere, but it’s a much more convincing story to show how your product or service would react to a real world environment that your prospective customer is a part of, at that moment.

There were a number of OEM/ODM type network (and server) manufacturers, as well as software-defined networking companies like Cumulus and 128 Networks, but I think at least one big name would have to be there to make InteropNet work. Two or three would make it even better.

One interesting thought to make InteropNet more interesting and practical would be for a hardware refurbisher or reseller to bring in gear from the big names and set it up. Whether it’s ServerMonkey or another vendor of that class, or even a broad spectrum integrator like Redapt, it would be a good way to show a less-than-bleeding-edge production-grade environment that might appeal more to the half of the attendees whose companies are smaller than 1000 people. It would be a great opportunity for companies like that to showcase their consulting and services offerings as well.

Looking into the rsts11 crystal ball…

I don’t remember any mention of venue for next year, but I would guess some rooms and locations would be tweaked to optimize MGM Grand for InteropITX 2018. It’s very convenient for economical rooms and minimal leaving-the-hotel-complex requirements for attendees.

The new tracks structure worked, for the most part, although I expect adjustment and evolution in the content. Don’t be surprised if more hands-on sessions come around. Even though wireless tech was in short supply in the Business Hall, it was very popular in the breakouts.

I’m not expecting the Monsters of IT to have a resurgence in 2018, although it might be a good thing if they did. More security, management and automation, and some surprising new startups, are more likely to find their way into the Business Hall.

Where do we go from here?

I was asked at Interop for suggestions on how to make InteropNet more practical next year. I had some ideas above, but I could use some help. Do you feel that it was an unfortunate omission, or were you more inclined toward “I wouldn’t say I was missing it, Bob” ??

We’ll have some more coverage in the next couple of weeks, including another update on NBase-T network technology (which made a much more substantial showing in terms of available-to-buy-today offerings this year), so stay tuned to our “interop” tag for the latest.

And of course, while it’s too early for me to apply for media credentials, it’s not too early to start thinking about InteropITX 2018.

Registration isn’t quite ready yet, but you can sign up to be notified (and get updates on submitting to present next year as well!). Click above or visit interop.com to join the notification list today!

Disclosure: I attend InteropITX as independent media, unrelated to and unaffiliated with my day job. Neither UBM/InteropITX nor any vendor covered have influence over or responsibility for any of my coverage.

What verse are we on? The fifth! Back at Interop ITX Las Vegas

I’m back in Las Vegas for my fourth time this MLife season, and my fifth time at Interop (now Interop ITX). And it’s a little bit different this year. [Disclosures below]

Quick takes:

The most obvious change is the venue; they announced at the end of Interop 2016 that the event would move to MGM Grand’s Conference Center, one  Las Vegas block down the Strip from its previous home at Mandalay Bay. This means a smaller, more focused event, as MGM has a smaller facility than Mandalay, but it likely also means more affordable accommodations at the event hotels. (I would have enjoyed an extra Amex FHR stay at Delano, but Signature at MGM is good enough.)

Some staff changes have happened, particularly Meghan Reilly taking the reins of the event from Jennifer “JJ” Jessup, who moved on to a different company and role after last year’s event. JJ and the team encouraged me to stay involved with the event even after going to the Dark Side, and I’m grateful for her influence over the past few years. But I haven’t seen any fallout from the transition yet. The staff keeps things going, even with the traditional Monday hiccups on food and beverage logistics.

There also seems to be more of a focus on the educational content as opposed to the expo floor. Well over a dozen in-depths events will occupy each day Monday and Tuesday, with prominent names from various corners of the IT ecosystem. The “Business Hall” is still there, and will have about a hundred exhibitors according to the Interop website, but people have noticed many of the big names of past years scaled back or passing on the event altogether.  I’ve also seen some of my perennial favorites sit this one out.

I would say both of these items are good, for various reasons. While it was beneficial to have the Monsters of IT(tm) on the floor pitching their latest wares, I would expect this year to allow more of a focus on new, more agile, more adaptable players in the market. And with what seems (to me at least) to be a stronger focus on content vs exhibitors, the event becomes even more of a unique, substantially community-driven, substantially vendor-independent tech conference.

It’s true that if you want to see Cisco, Dell, and HP side by side, you’re mostly out of luck unless you find a third party proprietary conference (like VMworld or SAP Sapphire), but I expect that increased exposure to the new and rising players will have a positive effect on some of the larger companies. As each of the giants realizes they can’t differentiate based on their own true believers alone–and to be honest, that’s the core of each vendor’s own conference–perhaps they’ll come back to the table.

It’s also true that, if you are looking for more general IT and technology coverage than the USENIX events offer, especially around the business and culture side of IT, Interop ITX is pretty much the only game left in town.

Where do we go from here?

I’ll be heading into some content today and tomorrow, in between working on some other slides and writing. If you’re brave, follow me on Twitter at @gallifreyan for realtime observations, or if you’re attending Interop ITX, follow me on the app.

Disclosure: I attend Interop as independent media, on personal vacation time, not under the auspices of my day job. Tech Field Day generously brought me here my first two years, but for the past three years inclusive, I have attended on my own dime (although Interop does provide media attendees with lunch and coffee as well as full access to the conference). Any opinions in my coverage of the event are mine alone, and have not seen prior review by anyone involved in the event.

Further disclosure: autocorrect is being religious as I write this on my iPad. JJ’s last name became Jesus quite often, and apparently Apple wants Interop to have a stronger focus on convent. I’ll have nun of that, thank you.

Overkill in the rsts11 lab workshop – a homelab update for 2017

After being chosen as a VMware vExpert for 2017 this month, I was inspired to get working on refreshing my vSphere “homelab” environment despite a busy travel month in late February/early March. This won’t be a deep technical dive into lab building; rather, I just wanted to share some ideas and adventures from my lab gear accumulation over the past year.

As a disclosure, while I do work for Cisco, my vExpert status and homelab building are at most peripherally-connected (the homelab at home connects to a Meraki switch whose license I get an employee discount on, for example). And even though I’m occasionally surprised when I use older higher end Dell or HP gear, it’s not a conflict of interest or an out-of-bounds effort. It’s just what I get a great deal on at local used hardware shops from time to time.

Lowered Expectations – How Low Can Your Laptop Go?

[An Interop Aside: I visited with a couple of vendors at Interop who are sending some gear for me to explore. I’m holding off on their coverage until that happens, although another summary post may be forthcoming.]

I’m a big laptop fan. Afficionado, not cooler, mind you. It’s a problem, especially since my recent rebuild acquisitions and components are blocking the fireplace at the moment.

There’s been a disturbing trend over the last couple of years, whereby laptop manufacturers decide to move more toward the netbook specifications for memory (and often storage), rather than to the state of the art for the current generation of laptop processors. I was commiserating with my friend John Obeto about this recently.

For a couple of months now, you’ve been able to order a Dell Precision 7000-series laptop with 64GB of RAM. That’s twice as much as many desktops can handle today. And even if you don’t have room for four DIMM slots in your laptop design, DDR4 16GB SODIMMs are very affordable and readily available even at retail. So there’s really no reason for a 13″ or larger laptop to have an 8GB limit.

But it is the way of the world, for most lightweight laptops these days. Even Dell’s remarkable XPS 13 9343 maxed at 8GB – the 9350 model this year has a 16GB option but it’s online order only (and in the $2000 range as I recall). Continue reading
