Editorial verdict

The lightest unit in the catalog (3.5 kg), with a 5-year factory warranty.

Best use case

Anyone who needs to keep a router, phone, or small medical device running during a power outage, in the lightest, cheapest-to-ship unit in the catalog.

256 Wh in a 3.5 kg unit. It doesn't replace the power to your refrigerator, but it keeps running what really can't go dark during a power outage: the router for internet, a phone, a small fan, or medical equipment like a CPAP.

Charges to 100% via AC power in about an hour, and with the 110W solar panel (optional, not included) reaches 100% in 2.3 hours of sun. Comes with a 5-year factory warranty — more than many products in this range offer.

Pros

  • Very light and easy to ship (3.5 kg)
  • Full charge in about 1 hour via AC power
  • 5-year factory warranty

Cons

  • Not enough capacity for cooling or A/C
  • The solar charging cable isn't included, sold separately
  • The DELTA 3 Classic offers more capacity for anyone needing more runtime

Ideal for: Anyone who needs to keep a router, phone, or small medical device running during a power outage, in the lightest, cheapest-to-ship unit in the catalog.
