The quick answer
Choose EcoFlow if…
- You want to recharge it from the mains as fast as possible.
- You think you'll need to add extra batteries later on.
- You'll mainly use it at home, as fixed backup.
Choose BLUETTI if…
- You want a compact unit to move between home, the campervan or a second home.
- You want an official 5-year warranty when buying from its shop.
- You'll often recharge it with solar panels.
For a power cut at home, both are more than capable: they keep the fridge, router and lights going for hours and work as a UPS. The difference is in how you'll use them, not in quality.

Where they really differ
Mains recharging speed
EcoFlow wins by a small margin. With X-Stream charging and 1,500 W of input, the DELTA 3 Plus goes from 0 to 100% in under an hour; the BLUETTI reaches 80% in 45 minutes and takes about 70 to fill up. In practice it matters little during a power cut, because once the power is off you can't charge. It does matter if the power comes back for a while between cuts, as often happens during storms: the faster it charges, the more you make of that window.
Long-term capacity
This is the most important difference. The DELTA 3 Plus accepts extra batteries up to 5 kWh, so you can start with 1 kWh and grow if you ever want to cover long outages. With the Elite 100 V2, if you need more capacity later you'll have to buy another station. If you're sure 1 kWh is enough, this advantage no longer counts.
Solar charging
A technical draw: both accept 1,000 W of panels and fully charge in about 70 minutes in good sun. If you'll use it with panels in a second home or a campervan, both brands sell compatible panels in their Spanish shops.
Use as a UPS
Both work as an uninterruptible power supply: if it's plugged in and the power goes, they switch to battery in about 10 milliseconds, so fast that your computer or router won't turn off. It's the feature most valued by people who work from home or use medical equipment such as a CPAP machine.
The two brands in Spain
EcoFlow has an official shop for Spain (es.ecoflow.com) and a very wide range, from compact models to whole-home systems. Its ecosystem is the most complete: extra batteries, panels, smart generators and app control.
BLUETTI also sells directly in Spain (es.bluettipower.eu), with an official 5-year warranty on the Elite 100 V2 when bought from its shop.
Tip for international residents: buy from the official Spanish shop or an authorised seller. That way the warranty, service and returns are handled in Spain, and the sockets are Schuko (EU). If you have UK appliances, you'll need a UK-to-EU adapter rated for the appliance's power.
Which one to choose for your situation
Home backup for short cuts
Either one. Decide on price on the day you buy: they're equivalent in what matters during a power cut.
Long cuts, or worried about falling short
EcoFlow DELTA 3 Plus, because you can add capacity without replacing it.
Home, campervan and second home
BLUETTI Elite 100 V2: compact, very good solar charging and a 5-year official warranty.
Remote work or medical equipment
Either one, always left plugged in as a UPS between the socket and your devices.

Frequently asked questions
Is EcoFlow or BLUETTI better?
Neither is better at everything. EcoFlow stands out for charging speed and expandable capacity; BLUETTI for its compact format, solar charging and 5-year warranty on the Elite 100 V2. For a power cut at home, both do the job.
How long will a fridge run on a 1 kWh station?
A modern fridge-freezer uses an average of 40 to 60 W over the day. With 1,024 Wh you can expect roughly 15 to 20 hours, a little less if other devices are connected too.
Can I keep it plugged in all the time as a UPS?
Yes, both are designed to sit permanently between the socket and your devices, and switch to battery in about 10 milliseconds when the power goes.
How many years will the battery last?
Both use LiFePO4 cells rated for about 4,000 cycles before dropping to 80% of capacity. As home backup, with few cycles a year, they should last well over a decade.
