EcoFlow DELTA 2 vs Bluetti Elite 100 V2

On battery and inverter, these are the same station on paper. Same rated capacity, same continuous AC output, same car port limit. Our data has no efficiency figure from either maker, so we apply the same assumed one to both, and every runtime on this page comes out identical. If hours are what you’re comparing, our data can’t separate them. Two specs do differ, though. The Bluetti Elite 100 V2 takes twice the solar input of the EcoFlow DELTA 2. The DELTA 2 has a published surge rating, and the Elite doesn’t.

Specs side by side

Why the runtimes match

Our runtime is rated capacity, times an efficiency factor for the power path, divided by the appliance’s draw. With the same capacity and the same assumed efficiency, the answer is the same. Here’s a Starlink Mini as an example:

And a Dometic CFX3 45 on Dometic’s hot-day figure:

Two different inverters can lose different amounts of power, so in real use one of these may go a bit further than the other. We have no figure for either, so we can’t say which. You’ll find the same pattern with laptops. Using the charger rating as the draw, the Lenovo ThinkPad T14 Gen 6 (Intel) gets 13.5 hours on the DELTA 2 and 13.5 hours on the Elite. A gaming laptop like the ASUS ROG Zephyrus G14 (2022, GA402) gets 3.5 hours and 3.5 hours. Charger ratings are a maximum, so in ordinary use both laptops should run longer than that. Our laptop page explains why.

Solar input

This is the row that matters if you charge from panels. The Elite 100 V2 can take in twice as much solar as the DELTA 2, so with enough panel it refills from the sun a lot faster. “With enough panel” is the catch. If your panels add up to less than the DELTA 2’s limit, both stations take in the same power and fill at the same speed, and the Elite’s higher limit does nothing for you. It starts to pay off once your array goes past the DELTA 2’s limit.

Our solar input guide explains how the input limit and panel wattage interact, and the solar recharge calculator will show you the hours for your own panels on each station.

Surge

The DELTA 2’s manual gives a surge rating above its continuous one. Bluetti’s manual for the Elite 100 V2 doesn’t give one. It mentions power lifting, but that’s a different feature, not a surge figure. So when our tables check a startup draw against the Elite, they use its continuous rating as the limit. That’s our cautious choice, and the Elite may well handle short spikes above it. The manual just doesn’t let us say.

Where you’d feel this is a compressor or motor load. Take the LG LW8017ERSM 8,000 BTU window AC window unit:

Both carry its rated running power, and both rows say “surge unverified”, because LG doesn’t publish a startup figure. The difference is that with the DELTA 2 you have a surge rating to compare against if you can find the unit’s startup draw. With the Elite, you’d have to ask Bluetti. Our surge watts guide goes into why that start matters.

Picking between them

Pick the Elite 100 V2 if you’ll charge from solar and have, or plan to buy, enough panel to go past the DELTA 2’s input limit. Pick the DELTA 2 if you’ll plug in things that kick on hard, like a window air conditioner or a power tool, and want a published surge rating to check them against. If you’ll mostly charge from the wall and run small steady loads, our numbers don’t pick between them.

We don’t carry weight, size, wall charging speed or expansion batteries in our data. With runtime this even, those are worth checking in both manuals.
