FAQ
Which expansion battery works with the BP3000?
The B2000L. The older B2000 is for the BP2000 family. Message us if you're unsure and we'll confirm compatibility.
Can it run a refrigerator?
Yes. Most full-size refrigerators draw 100–200W while running and a brief surge when the compressor starts, which this unit's rated output covers. Runtime depends on the fridge and how often the door is opened.
Backed by a 2-year warranty. Ships from a US warehouse with duties already paid, so there are no surprise fees at delivery. Always check that your appliances' running and starting watts fit within the unit's rated output.
