Jackery PowerBar review

Today, I’m bringing to you a new portable power bank, but it’s unlike the dozens we’ve reviewed here over the years. The Jackery PowerBar can power an AC device, as well as those USB-powered items in your kit. How’s that for differentiation?

Design and features

When you first hold the PowerBar, you think “Hmm. Standard power bank, just square and a bit heavy for a new item of this capacity.” Then, you look at the end opposite the input and the power button and – wait. Is that an AC outlet? This is a game-changer!

The PowerBar 77 is a square, sleek metal box of power. The ports and other interface elements are all on the small faces, with an AC port on one end and 2 USB-A jacks and a USB-C jack on the opposite end. The matte finish of the sides gives plenty of gripiness while not appearing industrial.

On the multi-port face, there is an on-off button that activates it. An LCD meter is on when it’s active and shows the power available.

The AC outlet requires venting, so there are mesh windows on the sides parallel to the plug blades, and a fan turns on when the power is activated. This fan is so quiet that I have never noticed it unless I actually put the unit up to my ear in a relatively quiet room.

What I Like

  • AC power!
  • USB A and C output
  • Multiple input options

What needs to be improved

  • None that I could find.

Final thoughts

Power packs are a fact of life until the invention of wireless dedicated power or something else Star Trek/Star Wars worthy. Everything we do, at least online, requires power. While batteries have progressed a huge amount in the last dozen years, they are still not able to run phones, laptops, and tablets forever. Usage costs power. Carrying around a source of power is easy with a power pack, but there’s always a trade-off. Weight, heat, or ventilation will affect the amount of power available and what type of power it is – AC or DC. The Jackery Powerbar, while a bit heavy for the amount of power it offers, adds a clear advantage in the AC power plug it offers. Count me as a fan. If you’re needing juice for your laptop or another AC device, you’ll be one, too.

  2. Great find! Another item added to my gift lists (and my personal list as well). Thank you.

    Did want to mention that your article goes back and forth between the 20,800 mAh (linked to) and the 23,200 mAh models, of which the later is $149.99 and not linked to. If you are willing to fork over the extra $20, you can get an extra ~10% boost in capacity from the 23,200 mAh model.

    1. Does the upgraded 23,200 mah model have the same dimensions as the 20,800 mah model? I ordered a protective pouch and hope that it will fit
