I have a a Jackery 1000 V2 which I used to power a beach party with some mates a few weeks back. Ran my decks , amp and passive PA speakers for a solid 8 hrs + a projector to watch the England world cup quarter final without a hitch. Powered down around 5am and checked the state of charge remaining and it still had 43% left in it. I doubt I would take it bankside as my small 20000 mah pack gives me enough if a boost to any tech I may take bankside on a 48hr session. If your a power user though or needing something for a longer session though it would be a winner.

I used the atom 2200 w last weekend and Bestival for 4 days alongside a 200w solar panel I was using a ninja wood fire bbq / airfryer 2400w a dualit kettle 3000w the atom will surge to 3000w so it’s actually under rated

The solar panel was restoring between15-20% per day and we also charged multiple phones, an Anker everfrost fridge and the eldest also used hair straighteners as well as a hair dryer all heavy use items - keep an eye out for theese and compare them with the brands that people are more familiar with and I think you’ll be pleasantly surprised if your in the market
