It’s gotten easier to get away with forgetting to take a laptop charger

SANTA CLARA, Calif.

Eighteen years ago, I managed to forget to pack my laptop’s charger for a transcon business trip, didn’t realize my oversight until reaching Dulles Airport, and then swore that I would never make that mistake again. Reader, you can guess what I did Tuesday morning.

In my inadequate defense, the compact, Wirecutter-endorsed charger I’d meant to bring is so small that its absence from my gadget-accessories bag was easy to overlook until I reached for it at the Capital One lounge at IAD. And the night before, its black USB-C cable was apparently too easy for me to overlook draped across the dark rug in my home office after I unplugged it from my laptop, tucked the laptop into the sleeve in my messenger bag, and then stupidly left the charger plugged into the wall.

But unlike in January of 2007, when I was heading to CES with a Dell laptop that needed a proprietary charger that I discovered was almost as rare in Vegas as a blackjack dealer handing you two aces in a row, this HP laptop charges via the same USB-C port as every other portable computer I own.

So I did not freak out but did resolve to stick to my phone for e-mail until I could get to my layover in Denver, where I knew multiple lounges would offer USB ports for the adapter cable I did still have tucked into that bag.

(That adapter cable is one of the best pieces of tech-event swag I’ve ever collected, as it includes a Qi cordless charger in a pod between its combination USB A/C plug and the USB-C, micro-USB and Lightning plugs at its other end. Whoever at Supermicro marketing picked this thing as a giveaway at HumanX in March, tell your boss I said you deserve a raise.)

After mostly recharging my phone in DEN, when I checked into the Hyatt Regency here Tuesday evening–where the organizers of TechEx North America are hosting me in return for moderating three panels at that conference–I asked if they might have a spare USB-C charger I could borrow. The rep at the front desk said they’d check, and barely a minute after I got to my room, somebody from housekeeping showed up with a new iPad charger.

I have to smile at a hotel bailing me out like this: I’d had to buy that compact USB-C charger after I’d left this HP’s original, larger power brick at a fancy hotel in D.C. during a conference there in February, after which nobody at the hotel was able to locate it even though I’d taped my business card to the thing.

One lesson of this episode is that by ensuring that devices finally use the same connector, the tech industry finally solved the problem of needing to find the right charger for a laptop, phone or tablet. It’s worth recognizing when these companies do something right–even if in Apple’s case, it seems to have required a shove from European Union regulations that made USB-C a required standard.

The other is that since I’m developing a bit of a history of leaving a laptop charger at home, I need to get myself into the habit of unplugging that thing from the outlet before I unplug it from my laptop.

So, I have two devices, one a Bluetooth speaker and one the 12-bar VU Meter LED setup I tooted about earlier, that want 5V power input via USB-C.

(I had been sharing a single USB-A charger block w/ A-to-C cable between them, swapping.)

So, I ordered two Anker Nano Charger / 511 devices and two USB C-to-C cables to go along with.

This device: anker.com/products/a2637-nano-

I plug them in and ... neither device powers up with that power input. The BT speaker makes a little clicking sound every few seconds - nothing from the LED VU meter.

Specs on the charger state: "Specs Input: 100-240V~0.6A 50-60Hz Output: 5V == 3A / 9V == 2.22A"

This is the second time I've seen a USB-C charger block not power such power-only devices.

What's up here? Do I need to keep with USB-A chargers and cable it to USB-C?

FWIW, the VU Meter device states not to allow more than 5V to the device -- but that should be the default, as I understand it, 5V from USB-C.

Any thoughts? Thanks.

It's more convenient to have a inside of a with all other components, but with an external , there is the potential for it to be in the future (like with chargers).

Wife just came into the computer/radio/man cave and said I need one of your bricks.
To which I said, I don't have any bricks..... I had no idea what she was talking about....
Then she picked up a USB charger/Adapter - to which I said, that's an adapter.....

Now to be fair, I have heard people call these bricks, but that was a long time ago. And I don't think I've ever heard her call it a brick. I think she's only ever called it a charger.....

USB chargers/power adapters   that some people might call bricks..... No me, but some people.
