Portable battery packs with USB ports are a dime-a-dozen, but your options are a lot more limited if you need a portable AC outlet. The new Jackery PowerBar though is a great option at a solid price.

The PowerBar is a big battery pack, let’s get that out of the way right off the bat. It’s pretty similar in size to a tallboy beer can, albeit with flat sides, so you aren’t going to be sticking this in your pocket. But in that package, you’ll find a 20,800mAh battery pack, two USB ports (one of which features Quick Charge 3.0), a USB-C port that doubles as the input, and yes, a 100W AC outlet that can charge a laptop, power a lamp, or even run a small TV for a time.

Let’s compare to this RAVPower pack, a larger version of which I’ve tested previously. The Jackery’s AC outlet is more powerful (100W vs. 50W), it’s cheaper ($115 with this deal vs. $146), and it recharges over USB-C, so you don’t have to carry an extra proprietary charger to juice it back up. Wins all around.

For a limited time, our readers can preorder the PowerBar through Indiegogo for $115, or $14 less than the current Early Bird pricing tier for everyone else. It’s not expected to ship until the holidays, but they sent me an early version, and it works as advertised.
