Frequently Asked Questions

Can I use devices while it's charging?

Yes. EcoFlow power stations support pass-through charging, so you can power devices and recharge simultaneously. Continuous pass-through charging at high loads over extended periods may generate heat; for long-term daily use, EcoFlow recommends cycling the battery normally.

Is it safe to use indoors?

Yes. EcoFlow power stations produce zero emissions and are completely safe to use indoors, unlike gas generators. They are quiet and require no ventilation.

Can I expand the capacity?

Many EcoFlow power stations support extra battery expansion. Check the product page for compatible extra batteries that can significantly increase total storage capacity.

How many charge cycles does the battery last?

EcoFlow uses LFP (lithium iron phosphate) battery chemistry rated for 3,000+ charge cycles to 80% capacity - equivalent to roughly 10 years of daily use.

What solar panels are compatible?

EcoFlow power stations are compatible with EcoFlow's portable solar panel lineup as well as most third-party panels using MC4 connectors. Check the product's maximum solar input wattage before sizing your panel array.

Does it come with a warranty?

EcoFlow power stations come with a 5-year warranty when purchased from an authorized reseller like Solwel. Contact us at kyle@solwel.com for warranty support.
