Pros

- High capacity
- LiFePO4 reliability
Cons
- Ungrounded outlets
For RV-ready setups, the EcoFlow DELTA 3 stands out because it balances usable whole-house power with LiFePO4 battery reliability. With 1024 Wh capacity and up to 1800 W continuous AC output, it can run common campsite loads like a microwave, coffee maker, or RV accessories without the constant shutdowns that weaker inverters can trigger. It also recharges fast from wall power at up to 1500 W, and supports up to 500 W solar input, which matters when you want to top up between stops.
One trade-off to note: the outlets are not grounded, so it may not be the best choice for gear that depends on a grounded connection. At 27.6 lb, it is carryable for car use and short moves around the site, but it is not something you will want to lift frequently during daily RV routines.
