Update, November 2026: the Anker SOLIX S2000, C2000 Gen 2 and F3800 Plus mentioned below are not currently available at RV Parts Giant, so some of the bundles named here are not for sale. For what is in stock, see Anker SOLIX Portable Power Stations (including the C1000 Gen 2 and F3000) and Anker SOLIX Home Energy.
The short version: EcoFlow optimizes for clever software and fast charging. Anker SOLIX optimizes for raw output and a very high expansion ceiling. Jackery optimizes for being simple and, in one specific case, for RVs: the HomePower 3600 Plus has a native NEMA TT-30 outlet, so a 30-amp trailer plugs straight in. Anker's C2000 Gen 2 and F3800 Plus now list a TT-30R as well, so if you tow a 30-amp trailer the choice narrows to Jackery or Anker. If you want maximum watts or a house-scale battery, Anker and EcoFlow are genuinely strong.
The three design philosophies
Spend an hour with all three spec sheets and a pattern shows up.
EcoFlow builds around software. Their X-Boost feature lets a unit run appliances above its rated output by shaping the waveform, so a 1,800W station will drive a 2,600W load. They quote 10ms switchover, 0 to 80% in 45 minutes on some models, and their larger units let you set per-circuit priority in the app. The trade is complexity, and a product line that is genuinely hard to navigate.
Anker SOLIX builds around headroom. Their C1000 Gen 2 puts 2,000W rated and 3,000W peak into a 1,024Wh box, which is more output per watt-hour than either rival. Their F3800 does 6,000W at 120V/240V and scales to 26.9kWh on one unit, or 53.8kWh across two. They also chase efficiency: the C2000 Gen 2 advertises a 9W idle draw, which matters more than people think when a station sits on standby for days.
Jackery builds around not making you think. Fewer models, fewer modes, fewer acronyms. The numbers are usually mid-pack rather than best-in-class, with two exceptions that matter to RV owners: the TT-30 outlet, and expansion ceilings that beat Anker at the 2kWh size.
The connector that decides it
If you tow a 30-amp travel trailer, this is the paragraph that matters.
A 30-amp RV shore cord ends in a TT-30 plug. The Jackery HomePower 3600 Plus has a TT-30 outlet on the unit, so the cord goes straight in and the whole coach is live.
Anker lists NEMA 14-50 and L14-30 ports on the F3800 for EV and RV charging. Those are the 50-amp RV socket and a 240V twist-lock. Both are useful, neither is a TT-30. The F3800 Plus and the C2000 Gen 2 are different: Anker's spec tables list a TT-30R on both (120V, 25A and up to 3,000W on the F3800 Plus; 120V, 20A and 2,400W on the C2000 Gen 2), so a 30-amp shore cord plugs straight in, within those limits. EcoFlow's DELTA Pro 3 delivers 120V and 240V but again does not list a TT-30 output.
So: 50-amp coach, the original F3800's 14-50 is a direct match. 30-amp trailer, the Jackery, the Anker C2000 Gen 2 and the F3800 Plus plug straight in, and EcoFlow needs an adapter or a transfer switch. We go into this properly in which Jackery runs a 30-amp travel trailer and running a 30-amp RV on an Anker SOLIX.
Around 1kWh
The Jackery Explorer 1000 v2 is 1,070Wh and 1,500W at 23.8 lb, full in about an hour, and it has the most capacity of the three.
Anker's C1000 Gen 2 is 1,024Wh but 2,000W rated and 3,000W peak, with a full recharge in 49 minutes at 1,600W and 4,000 cycles. On paper it is the stronger machine, and if you want to start a power tool it is the one to have.
EcoFlow's DELTA 3 Classic is 1,024Wh and 1,800W with a 3,600W surge, X-Boost up to 2,600W, a 10ms auto-switch and 0 to 80% in 45 minutes.
Honest verdict: Anker wins on output, EcoFlow on features, Jackery on capacity and simplicity. Full detail in the 1kWh shootout.
Around 2kWh, where expansion decides it
All three sell a 2,048Wh-class unit at roughly 2,400W. The specs are close enough that the real question is how far each one grows.
- Jackery HomePower 2000 Plus v2: 2,048Wh, 2,400W, expands to 12kWh with five Battery Pack 2000 Plus v2 units.
- EcoFlow DELTA 3 Max Plus: 2,048Wh, 3,000W rated and 6,000W surge, expands to 10kWh, with per-circuit output priority in the app.
- Anker C2000 Gen 2: 2,048Wh, 2,400W rated and 4,000W peak, 9W idle, but expands only to 4kWh with one BP2000 pack.
Anker has the most efficient standby and 800W alternator charging. EcoFlow has the most output. But if you expect to grow the bank, Anker's 4kWh ceiling is a hard stop that the other two clear comfortably. More in the 2kWh comparison.
The big units
Here Anker and EcoFlow are ahead on paper and it is worth saying plainly.
Anker's F3800 is 3,840Wh with 6,000W at 120V/240V from one unit, and scales to 26.9kWh with expansion batteries, or 53.8kWh across two units. The F3800 Plus adds up to 3,200W of solar with dual MPPT and 240V bypass charging from a gas generator. EcoFlow's DELTA Pro 3 is UL 9540 certified, does 120V and 240V at 4,000W with X-Boost to 6,000W, and scales from 4kWh to 48kWh.
Jackery's answer at that size is the HomePower 3600 Pro Max at 3,584Wh with 4,000W at 240V, UL 9540 certification and 43kWh of expansion, or the Explorer 5000 Plus at 5,040Wh and 7,200W with NEMA 14-50 and L14-30R. Both are competitive. Neither out-specs an F3800 on raw output.
If your goal is whole-home backup and you do not care about an RV connector, shop all three on price and expansion. If your goal is a camper, the calculus changes.
What none of the spec sheets tell you
Two practical things matter more than the headline numbers.
Idle draw. A station that sits on standby in a camper for a week loses capacity to its own electronics. Anker publishes a 9W idle figure on the C2000 Gen 2. Most brands do not publish this at all. Lower is better and it is worth asking about.
How you refill it. Capacity is only half the system. A DC-DC alternator charger that pulls 600W while you drive, or a 500W folding array at camp, changes the usable capacity of any of these brands far more than a few hundred watt-hours of difference between them.
A note on prices. Our prices change often, so we leave them out of this comparison; check the current price on each product page. Found it cheaper? We'll beat it. We do not quote EcoFlow prices either: EcoFlow discounts hard and runs member-only and flash-sale pricing, and on the day we wrote this it listed the same DELTA 3 Max under more than a dozen different prices at once. Check the current price yourself before you decide on cost.
FAQ
Which brand is most reliable?
All three now use LiFePO4 cells with 3,000 to 6,000 cycle ratings and 5-year warranties on their current lines. There is no honest reliability gap between them at the spec level. Judge on support and on who actually answers the phone.
Is X-Boost a gimmick?
No, but understand what it does. EcoFlow shapes the output so a resistive appliance draws less than its rating. It works well on heaters and kettles and less predictably on motors. Do not buy a smaller unit expecting X-Boost to cover an air conditioner.
Why don't you sell EcoFlow?
We stock the lines we can buy properly and support: Jackery, BLUETTI and, since October 2026, Anker SOLIX. We would rather stock a few brands well than list ones we cannot get parts or answers for.
Which would you buy for a 30-amp trailer?
The HomePower 3600 Plus, for the TT-30 outlet, unless you need more than 3,600W continuous. If you would rather have Anker, the F3800 Plus has a TT-30R rated up to 3,000W and the C2000 Gen 2 has one rated at 2,400W.
We sell Jackery, BLUETTI and Anker SOLIX, not EcoFlow, so treat this as what it is: our read of the specs, written by people who sell two of the three. We have tried to be straight about where each one wins. If you want help sizing a system for your rig, talk to a parts person before you buy.
Update, October 2026: we now carry Anker SOLIX, including the C1000 Gen 2, S2000, C2000 Gen 2 and F3800 Plus. Anker now lists a TT-30R outlet on the C2000 Gen 2 and F3800 Plus, so Jackery is no longer the only one of the three with a TT-30 receptacle. Compare the four in which Anker SOLIX power station for an RV.
