EcoFlow Delta 2 Portable Power Station review
Keeping a fridge, router, phones and a few lights running through a multi-hour power cut.
By Tom Calder
We no longer recommend this model, so it no longer appears in our buying guides. In its place, we now recommend EcoFlow DELTA 3 Classic Portable Power Station in our Power stations guide.
A dependable, sensibly-sized 1kWh unit with long-life LFP cells and unusually fast mains recharging, which makes it well suited to short-notice outages. It is one of the safest default choices in this class, provided you match its capacity to what you actually need to run.

- Long-life LFP battery (3,000+ cycles) backed by a 5-year warranty, so it should outlast cheaper lithium rivals
- Recharges from flat to 80% in around 50 minutes on a standard UK socket, useful before a forecast storm
- 1,800W output (2,400W via X-Boost) covers most household essentials, and capacity expands to 2,048Wh with an add-on battery
- At ~12kg it is a two-hands lift rather than something you'll carry far
- The cooling fan is audible under heavy load, and 1,024Wh won't run high-draw items like a kettle or electric heater for long
Who shouldn't buy this
You only need to keep phones, a tablet and a laptop going — a £60-90 power bank does that for a fraction of the cost and weight; step up to this only if you need to run mains appliances like a fridge or router.
