Strengths and limitations

Strengths

  • 3,840 Wh LFP, rated for 3,000+ cycles (Anker).
  • 6,000 W max AC output at 120 V and 240 V (Anker).
  • Two solar inputs, 1,600 W max each (Anker).
  • Up to six 3.84 kWh expansion batteries (Anker).
  • Powers only what plugs into it, so no interconnection rules apply to that use.

Limitations

  • 136.7 lb including wheels (Anker).
  • Anker's page gives two different maximum capacities: six expansion batteries come to about 26.9 kWh, while its marketing copy says 53.8 kWh.
  • No UL certification named on the product page.

What it does not do

  • Back up your house circuits by plugging into an outlet: that needs a transfer switch or Anker's Home Power Panel, installed by an electrician.
  • Move easily: it weighs 136.7 lb with wheels.
  • Fly: it is far above the FAA's 160 Wh limit for passenger aircraft.

Power and travel notes

Rated capacity: 3840 Wh. Over 160 Wh: forbidden on passenger aircraft per FAA. Shipping by carrier follows separate DOT and carrier rules.

Real runtime is less than capacity divided by load: conversion losses, battery reserve and temperature all cut into it. Size a battery for your fridge.

Before you buy

  • Over 160 Wh: not allowed on passenger aircraft per the FAA.
  • Connecting any battery to your home wiring needs a transfer switch or interlock installed by a licensed electrician.
