RAVPower 27,000mAh AC Battery Pack, $139 with code kja27000 | 20,100mAh, $110 with code kja20100

You guys, they’re finally here. USB battery packs with an actual, bona fide AC power outlets built in.

Obviously, they’re larger and more expensive than USB-only battery packs with a similar capacity, but RAVPower’s portable chargers still only weighs 1.9 pounds, and can charge your laptop via built-in AC outlets (100W on the larger model, 65W on the smaller). That’s an amazing convenience for long trips, conferences, or anywhere else that power is at a premium. And of course, you also get USB ports as well, in both standard and USB-C flavors.


I tested a slightly earlier version of this battery pack last year (the only major difference was the lack of a grounding prong), and it worked as advertised.

At $139 for 27,000mAh, or $110 for 20,100mAh, you’ll certainly be paying a premium for that power outlet, but if you’ve been waiting for a product like this for years, it’ll be money well spent.
