Our verdict

The most capacity for the money under $200, if you can live with slow charging.

Twice the capacity of the 300 Wh units for about the same money, with two 500 W pure-sine outlets. The catch: slow charging, an unstated battery chemistry and a third-party seller.

Ideal for

Occasional use — craft fairs, camping lights, a router during short outages — on a strict budget.

Skip it if

Daily cycling, fast turnarounds or anyone who wants a long-life LiFePO4 battery.

In-depth review

What it's like to own

GRECELL's EB500 is sold on Amazon under a generic title, but it's a straightforward 519 Wh box with two pure-sine AC outlets (500 W, 1,000 W surge), 60 W USB-C and three quick-charge USB-A ports.

At $180 that's about $0.35 per Wh, cheaper than anything else under $500. The listing doesn't say whether the cells are LiFePO4, and owners report that solar and car charging top out around 105 W, so a full recharge takes most of a day.

Recent buyers like the price and the carry handle; a craft-show vendor ran two lamps for nine hours with 40% left. Some reviews on the listing are for older GRECELL models.

Pros

  • 519 Wh for about $180
  • 2 pure-sine AC outlets
  • 60 W USB-C
  • 2-year warranty

Cons

  • Slow charging (~105 W solar/DC)
  • Battery chemistry not stated
  • Third-party seller
  • Heavier than LiFePO4 rivals of this size
