Amazon Prime Day officially got underway Tuesday, with the summer sales event slated to last through July 11. Competitors Target and Walmart are also holding multi-day sales events.

This Prime Day, the Jackery Explorer 1000 v2 is available at an all-time low price of $448, down from its usual $799. This is a Prime-exclusive deal, so you’ll need to be a Prime member to take advantage of this record low price. If you’re not Prime yet, you can grab the free 30-day subscription and get it too.
