Pros
  • 2 kWh in a 35.7 lb box small enough to keep in a kitchen corner
  • Battery rated for 6,000 cycles to 80%, so daily use for years is realistic
  • Recharged from the wall in under two hours in The Solar Lab test
  • Rear outlets keep an always-on fridge or router plugged in out of the way
Cons
  • Only 400W of solar input, so recharging from panels alone takes most of a day
  • No 12V car socket for coolers or other DC gear
  • 1,500W continuous output is low for a 2 kWh unit
  • Not expandable
