EcoFlow DELTA 3 vs BLUETTI Elite 100 V2: Which Fits Your Backup Plan?
Compare DELTA 3 and Elite 100 V2 by capacity, carrying weight, solar input, and transfer behavior, with the older AC180 as a useful reference.
How the options differ
Different households can reach different answers
We compare the US models using their manufacturer specifications and manuals, then interpret the differences for household backup planning. We have not tested either unit. Capacity is nominal battery energy, not measured AC output. We do not rank by commission, current price, star ratings, or advertised boosted-power modes. Per-field source dates appear in the specification table.
Best fit by need
You have a larger compatible solar setup: Examine Elite 100 V2
Its documented solar-input ceiling is higher than the base DELTA 3. Confirm panel voltage, current, connectors, and the energy you can realistically collect.
You are considering the EcoFlow ecosystem: Examine the exact DELTA 3 configuration
Confirm the base model, extra-battery compatibility, and cables with the manufacturer. Do not pay for an assumed feature borrowed from DELTA 3 Plus.
You prefer more base capacity in an older model: Keep AC180 on the shortlist
Its 1,152 Wh nominal battery is larger than the two newer units, but it is heavier and its solar-input ceiling is lower. Check the actual listing price and terms before deciding whether the tradeoff is worthwhile.
Your requirements exceed these models: Choose a different class of backup
All three US records are 120 V units. A 240 V load, much larger energy need, or critical-device requirement calls for another configuration.

Criterion
Why it matters
EcoFlow DELTA 3
BLUETTI Elite 100 V2
Stored energy and output
These establish different limits: duration and simultaneous load.
1,024 Wh nominal and 1,800 W continuous AC. Delivered energy depends on reserve, conversion loss, conditions, and the actual load.
Also 1,024 Wh nominal and 1,800 W continuous AC. Equal nameplate numbers do not establish equal measured runtime or startup behavior.
Solar input
Panel compatibility and actual sun conditions determine how much energy you can replenish.
The exact base DELTA 3 manual lists a 500 W solar-input ceiling. Do not use Plus or other variant specifications for this model.
The US manual lists a 1,000 W solar-input ceiling within its voltage and current limits. This may suit a larger compatible array, not guarantee faster charging every day.
Carrying
Base weight matters when moving between rooms, stairs, or storage.
About 27.6 lb before accessories. Confirm handles, clearance, and your intended route.
About 25.3 lb before accessories, somewhat lighter on paper. Handling comfort is not something we have tested.
Transfer and startup
The connected equipment must tolerate transfer interruption and receive the startup power it needs.
A documented 10 ms standby transfer and a separate 3,600 W surge figure. X-Boost does not replace checking your load.
A documented transfer time of 10 ms or less and a separate 3,600 W surge figure. Power Lifting is for specified resistive loads, not a general motor compatibility claim.
Before you order
Match the unit to your actual load
Write down simultaneous running watts, the largest startup demand, and measured daily
watt-hours. A larger Wh number does not raise the output limit.
Check the exact US model and bundle. Panels, expansion batteries, and charging cables may
be sold separately.
Read the seller, return, and warranty terms for the listing you select. A manufacturer
specification is not proof that every marketplace bundle is equivalent.
Plan a test with your actual equipment before relying on it. Neither a brief UPS transfer
time nor an advertised runtime guarantees compatibility with critical equipment.
The base DELTA 3 is a 1,024 Wh, 1,800 W portable station for selected 120 V essentials. Start with the exact model: DELTA 3, DELTA 3 Plus, and other variants do not share every charging specification.

The Elite 100 V2 combines a 1,024 Wh battery and 1,800 W AC output with a documented 1,000 W solar-input ceiling. Its lower listed weight makes it worth comparing with the older AC180 when carrying and solar charging matter.

The AC180 is a roughly one-kilowatt-hour, 120 V portable battery with 1,800 W continuous output and a documented UPS switching figure of 20 ms or less. Its slightly higher nominal capacity than the DELTA 2 comes with a heavier listed base-unit weight and no directly attached expansion capacity verified in this source record. It remains an older-model alternative to Elite 100 V2.
