BLUETTI B80 / B80P Expansion Battery | 806Wh

Two batteries in one. Endless places to take it.

Meet the BLUETTI B80 / B80P — the 806Wh powerhouse that refuses to be put in a box. Snap it onto your BLUETTI AC60 to nearly double your runtime, or set it free as a standalone power station with its own built-in outputs. Either way, you get dependable energy in a package light enough to grab and go.

Power That Pulls Its Weight — 806Wh

With 806Wh on tap, the B80 / B80P keeps the essentials running: phones, laptops, routers, cameras, lights, and the small electronics that matter most when you’re off the grid. It’s tuned for real-world portability over raw wattage efficient, packable, and ready whenever you are.

Plug In Without a Power Station

No main unit? No problem. The B80 / B80P stands entirely on its own with three onboard DC outputs:

  • 100W USB-C — fast charging for laptops and modern devices
  • 18W USB-A — for everyday electronics
  • 12V/10A Cigarette Lighter Port — for car accessories and DC gear

Built for the BLUETTI Ecosystem

This is the dedicated expansion unit for the AC60 but it doesn’t stop there. Run it in power bank mode to extend your AC180, EB3A, EB55, or EB70S. If you’re already living in the BLUETTI world, this is the upgrade that makes everything last longer.

Four Ways to Refill

Wherever you land, there’s a way to recharge:

  1. AC60 charging — top up straight from your power station
  2. Solar — soak up the sun for true off-grid freedom
  3. Car charging — power up on the move via the cigarette lighter
  4. Wall adapter — the easy at-home refill

Made for the Way You Actually Live

Compact body, no-fuss ports, flexible charging the B80 / B80P slots right into camping trips, RV road life, emergency phone and router backup, and remote-work setups. Lightweight backup power that shows up when it counts.
