Campers who recharge from panels should pick the BLUETTI Elite 100 V2. It accepts 1,000 W of solar, twice the EcoFlow DELTA 3 Classic’s 500 W, and BLUETTI says that refills it in about 70 minutes. Pick the DELTA 3 Classic instead if you mostly charge from an outlet and want a listed warranty and a higher X-Boost limit.
The numbers below come from BLUETTI’s and EcoFlow’s US spec pages, checked in November 2026, plus one Amazon listing detail for EcoFlow’s outlet count. We haven’t charged or run either model, so this compares listed specs only.
BLUETTI Elite 100 V2: the solar-first choice
BLUETTI Elite 100 V2
- Capacity
- 1,024 Wh
- AC output
- 1,800 W
- Solar input
- 1,000 W
- Weight
- 25 lb
Who it's for: Campers and small-space buyers who want about 1 kWh and 1,800 W at around 25 lb.
Strengths
- 1,000 W solar input, full in about 70 minutes
- 80% AC charge in about 45 minutes
- Listed at 30 dB under 600 W
Weaknesses
- AC charging tops out at 1,200 W
- Holds less than BLUETTI's own AC180
Fast solar is what sets the Elite 100 V2 apart. Its input takes 1,000 W at 12-60 V and 20 A. With enough panels connected, BLUETTI lists about 70 minutes from empty to full. It also charges from a car in about 1.8 hours with BLUETTI’s Charger 1.
The basics are solid. Its 1,024 Wh LiFePO4 battery is rated for 4,000+ cycles to 80% of original capacity, and its outlets share 1,800 W at 120 V. BLUETTI lists a 10 ms or less UPS switchover and 30 dB under 600 W. At about 25 lb, it is the lighter of the pair. In the box, BLUETTI lists an AC charging cable, a manual, and a grounding screw.
Wall charging is its weaker side. AC charging reaches 80% in about 45 minutes, but combined AC and DC charging tops out at 1,200 W. The warranty term is not listed on BLUETTI’s spec page, and neither is a boost mode for higher-watt devices.
EcoFlow DELTA 3 Classic: the wall-charging choice
EcoFlow DELTA 3 Classic
- Capacity
- 1,024 Wh
- AC output
- 1,800 W
- Solar input
- 500 W
- Weight
- 26.7 lb
Who it's for: Buyers who want a 1 kWh home or camping unit that refills from the wall in about an hour.
Strengths
- 0-80% in 45 minutes on AC
- 10 ms UPS switchover
- LiFePO4 battery
Weaknesses
- Solar input tops out at 500 W
- Full 5-year warranty needs app registration
- Only one 18 W USB-A port
The DELTA 3 Classic is better suited to a home or a site with power. Its 1,400 W AC input takes it to 80% in 45 minutes and to full in 60 minutes. A car, a generator, or EcoFlow’s 500 W Alternator Charger can charge it as well. EcoFlow lists a 10 ms switchover.
It holds the same 1,024 Wh of LFP and the same 1,800 W of total AC output. X-Boost runs suitable devices at up to 2,600 W. The warranty is 5 years once registered in the EcoFlow app, or 3 years without.
Its drawbacks: solar input stops at 500 W, which EcoFlow says fills it in 2.5 hours. It weighs 26.7 lb. Its USB-A port is a single 18 W one, and the listing photos show 3 AC outlets. An expansion battery isn’t listed.

Does one go further between charges?
Not on one charge. With equal batteries and an assumed 85% reaching your devices, each delivers about 870.4 Wh, enough for a steady 40 W load for roughly 21.8 hours.
Per pound, the Elite 100 V2 holds about 41 Wh and the DELTA 3 Classic about 38.4 Wh. The 1.7 lb gap is small. The bigger real-world difference is refill time off the grid: 70 minutes against 2.5 hours from a full-size array.
How to choose
- Solar is your main charger: the Elite 100 V2 accepts twice the solar power.
- You charge mainly from the grid: the DELTA 3 Classic reaches full in 60 minutes.
- One appliance slightly above 1,800 W: the DELTA 3 Classic’s X-Boost mode runs suitable devices up to 2,600 W, so check whether yours is one.
- You want a known warranty: EcoFlow lists 5 years with registration; BLUETTI’s spec page doesn’t list one.
- Quiet indoor use: the Elite 100 V2 lists 30 dB under 600 W.
