Conclusions
The EcoFlow Delta 2 is the best portable power station I’ve tested so far in its class. It’s great to see a long lasting LFP battery and reassuring that EcoFlow backs this up with a 5 year warranty. The modular battery system is a great idea – the 1024 Wh battery will probably be enough for most people and importantly keeps the weight and price down. This is far more portable than any other LFP power station I’ve tested and with all its features is pretty good value too. If you need extra capacity it’s easy to add another battery and it’s more convenient to move around two lighter batteries compared to one giant heavy battery.
There aren’t many features missing. It doesn’t have any wireless charging pads like the Bluetti AC200P, or a built-in light like many other units I’ve tested but more than makes up for it with the number of useful ports, the large 1800W inverter, the insanely fast 1200W charging and the genuinely useful smartphone app.
My only real criticism is the fan noise when charging at full speed and powering more demanding devices. But they do keep the unit cool and hopefully preserve the battery. I would have liked to have seen a MC4 to XT60 cable included too.
If you know you’re going to need more capacity, the Bluetti AC200P works out a little cheaper, already having a 2000 Wh battery and has a slightly larger 2000W inverter, even more flexible solar charging options and built-in wireless charging pads. But it’s over twice the weight, charges much slower with a bulky AC adapter and doesn’t have a smartphone app.
The Anker 757 costs a little more but has a slightly larger battery and a built-in light, but it’s considerably heavier and doesn’t have a smartphone app. The Jackery Explorer 1000 is about the same price as the Delta 2 with a similar sized battery. It has a standard Li-ion battery which won’t last as long, but that does make it the lightest option at around 10kg.
Jackery power stations are very user friendly and their solar panels are by far the easiest to set up and use – even though they do use a less standard 7.9mm adapter. But the Jackey is looking a little out of date compared to the others, with slow charging, a rather basic LCD screen and very limited USB-C outputs.
