The EcoFlow DELTA 3 Ultra Plus is a high-capacity portable power station paired with a 400W folding solar panel. It is built for home backup, off-grid living and long trips where you need to run fridges, power tools or a whole room for hours. The bundle adds solar charging so the station can refill without a wall outlet. Against smaller DELTA models it offers more capacity and output, but it is heavy and best treated as a semi-portable unit rather than something you carry on every outing.

It is built with automotive-grade full-tab LFP battery cells rated for over 10 years of use. It is made to withstand harsh environments, including humidity, salt spray and drops. A 10 ms automatic switchover (UPS) helps protect sensitive electronics.
The bundle includes a 400 W portable solar panel. It is a foldable, one-piece panel with monocrystalline cells and up to 23% conversion efficiency. Its protective case doubles as an adjustable kickstand, and the panel has an IP68 waterproof rating.
