EcoFlow, BLUETTI and Jackery make most of the portable power stations people compare, and on paper their models look alike. All three now use LiFePO4 (LFP) batteries, all three run 120 V appliances from a pure sine wave inverter, and all three charge from the wall, a car or solar panels. The differences that matter are in the details: how much solar a unit will accept, how heavy it is, whether you can add batteries later, and what the warranty really is.
This guide compares the three brands at the same size, so you aren't weighing a 1 kWh unit against a 2 kWh one. Prices and specs come from each maker's own US product page, checked on November 6, 2026. Prices change often, so confirm before you buy.
The short answer
- Lowest price and lightest at about 1 kWh: the EcoFlow DELTA 3 Classic or the BLUETTI Elite 100 V2. They are within $20 of each other and within about 1.5 lb.
- Most solar input at about 1 kWh: the BLUETTI Elite 100 V2, which accepts up to 1,000 W of panels. The EcoFlow DELTA 3 Classic takes 500 W and the Jackery Explorer 1000 Plus takes 800 W.
- Room to grow later: Jackery's Explorer 1000 Plus was built to take add-on battery packs, but Jackery says that pack is now discontinued, so check stock before counting on it.
- Best value at about 2 kWh: the BLUETTI Elite 200 V2 at $899 is about 43 cents per watt-hour, with 1,000 W of solar input. The EcoFlow DELTA 3 Max is lighter by about 9 lb but accepts only 500 W of solar.

The 1 kWh class: three units side by side
| Spec | EcoFlow DELTA 3 Classic | BLUETTI Elite 100 V2 | Jackery Explorer 1000 Plus |
|---|---|---|---|
| Price | $479 (list $599) | $499 | $619 (list $699) |
| Capacity | 1,024 Wh | 1,024 Wh | 1,264 Wh |
| Continuous AC output | 1,800 W | 1,800 W | 2,000 W |
| Surge / boost | 3,600 W surge, 2,600 W X-Boost | 2,700 W "lifting power" | 4,000 W surge |
| Max solar input | 500 W | 1,000 W (12–60 V, 20 A) | 800 W (12–60 V) |
| Max AC charge input | 1,400 W | 1,200 W | about 1.7 hours to full |
| Weight | 26.7 lb | 25.3 lb | 32 lb |
| Battery | LFP | LFP, 4,000+ cycles to 80% | LFP, 4,000 cycles to 70% |
| Warranty | 3 years, plus 2 with app registration | 5 years | 3 years, plus 2 on jackery.com orders |
| Price per Wh | $0.47 | $0.49 | $0.49 |
A few notes on that table:
- Price per Wh is our own math: the price divided by the capacity. It uses each maker's current price, not the list price.
- Surge figures are short bursts for motors starting up, not what you can run all day. Size for the continuous number.
- Jackery's weight is listed as 32 lb in its tech specs, even though one marketing line on the same page says "24 lb". We used the tech spec.
- BLUETTI's cycle rating is to 80% capacity, while Jackery's is to 70%, so they aren't measured the same way. EcoFlow's page gives a 10-year life estimate rather than a cycle count.
What the numbers mean in practice
Capacity. For planning, we count on about 80% of the label capacity reaching your outlet after inverter losses. That's our rule of thumb, not a maker's figure. By that rule, the Jackery's 1,264 Wh gives about 1,010 Wh of usable power, and the two 1,024 Wh units give about 820 Wh. A 100 W load, such as a laptop plus router, would run about 10 hours on the Jackery and about 8 hours on the others.
Solar input. This is the spec that separates them most. With 500 W of panels, the DELTA 3 Classic's page says a full charge takes 2.5 hours in ideal sun. BLUETTI says its 1,000 W input fills the Elite 100 V2 in about 70 minutes, also in ideal conditions. Real sun is weaker than the lab, so plan on longer. If you'll lean on solar for days at a time, a higher solar limit means you can recharge faster on a short winter day. You only benefit if you own enough panels to use it, though. A single 200 W panel won't come close to any of these limits.
Voltage window. All three accept panels between 12 V and 60 V on their solar ports. That means you wire panels in parallel or short series strings, not a long rooftop string.
Weight. The BLUETTI and EcoFlow are about 25 to 27 lb, which most people can carry one-handed for short distances. The Jackery's 32 lb is noticeably heavier, in exchange for the larger battery.
EcoFlow DELTA 3 Classic: lowest price, fast wall charging
EcoFlow lists the DELTA 3 Classic at $479, the lowest price of the three at this size. It has 1,800 W continuous output and an X-Boost mode that lets some heating-type appliances run up to 2,600 W by lowering the output voltage. X-Boost helps with kettles and hair dryers, not with motors, so don't count on it for a pump or a compressor.
It charges from the wall at up to 1,400 W, and EcoFlow lists 0 to 80% in about 45 minutes. It switches to battery in 10 ms when the power fails, which is fast enough for most computers and routers. The tradeoff is the 500 W solar limit, the lowest of the three.
Best for: home outage backup and a budget buyer who will mostly charge from the wall.
BLUETTI Elite 100 V2: most solar for the money, five-year warranty
The Elite 100 V2 is $499 and the lightest of the three at 25.3 lb. Its standout spec is the 1,000 W solar input, double the EcoFlow's. BLUETTI lists a five-year warranty for the Elite line, longer than the three years standard from EcoFlow and Jackery.
Two limits to know. It can't take expansion batteries, so what you buy is what you get. And BLUETTI's own spec says it doesn't charge below 32°F (0°C), which matters if you plan to leave it in an unheated cabin in winter. It can still run loads down to -4°F (-20°C), according to the same spec.
Best for: solar-first use, where you'll bring several panels and want fast recharging.
Jackery Explorer 1000 Plus: bigger battery and the most output
The Explorer 1000 Plus holds 1,264 Wh, about 23% more than the other two, and puts out 2,000 W continuous with a 4,000 W surge. It charges from the wall in about 1.7 hours and accepts up to 800 W of solar through two DC ports. It costs $619, about $120 to $140 more than the others.
Jackery's page says this unit can expand to about 5 kWh with up to three battery packs. However, the same page now states that the Battery Pack 1000 Plus has been discontinued. If expansion is why you're buying, confirm you can still get the packs first.
Jackery's product page also shows a mix of customer reviews, including warranty and customer-service complaints alongside plenty of praise. That's one reason we suggest registering your purchase and keeping your receipt, whichever brand you pick.
Best for: people who want the biggest battery and the most AC output at this size, and don't mind the extra weight.
The 2 kWh class: EcoFlow and BLUETTI
At about 2 kWh you can run a refrigerator, a few lights and a well pump's lighter loads for most of a day. These units weigh 45 to 55 lb, so they stay put more than they travel.
| Spec | EcoFlow DELTA 3 Max | BLUETTI Elite 200 V2 |
|---|---|---|
| Price | See EcoFlow's page (several bundle prices) | $899 |
| Capacity | 2,048 Wh | 2,073.6 Wh |
| Continuous AC output | 2,400 W | 2,600 W |
| Surge / boost | 4,800 W surge, 3,400 W X-Boost | 3,900 W for resistive loads |
| Max solar input | 500 W | 1,000 W (12–60 V, 20 A) |
| Max AC charge input | 100–120 V, 15 A | 1,800 W |
| Weight | 44.8 lb | 53.4 lb |
| Warranty | 3 years, plus 2 with app registration | 5 years |
The BLUETTI Elite 200 V2 gives you more output, double the solar input and a longer warranty. The EcoFlow DELTA 3 Max is about 9 lb lighter and lists a very quiet 25 dB at 600 W. We didn't list a price for the DELTA 3 Max because its page shows several bundle prices and we couldn't tie one cleanly to the standalone unit today. Check the current price on EcoFlow's page.
Jackery's equivalent, the Explorer 2000 Plus (2,042.8 Wh, 3,000 W), is listed on Jackery's site as discontinued, with the HomePower 2000 Plus v2 named as its successor. We didn't compare the successor here because it's a different product line from a portable unit.
Which should you buy?
- You want the cheapest decent backup for outages: EcoFlow DELTA 3 Classic.
- You'll charge from solar and want to refill fast: BLUETTI Elite 100 V2 (about 1 kWh) or Elite 200 V2 (about 2 kWh).
- You want the biggest 1 kWh-class battery and most output: Jackery Explorer 1000 Plus, and accept the weight and price.
- You need to run a well pump or a cabin's fridge: go to the 2 kWh size, and check the pump's starting watts first. Our solar well pump kit guide covers sizing.
- You want whole-house backup: none of these is the right tool. See our best solar generators for home backup.

Things to check before you buy any of them
- Total watts you'll run at once. Add up the running watts of everything that will be on together. Stay under the continuous rating, not the surge rating.
- Starting watts for motors. Fridges, pumps and compressors pull extra for a moment when they start.
- Your solar setup. Check the panel voltage against the unit's 12–60 V window, and the total watts against its limit.
- Cold weather. Most LFP units won't charge below freezing. If yours lives somewhere cold, check the charge temperature range on the spec page.
- The real warranty. The "5-year" warranties from EcoFlow and Jackery are 3 years plus 2 extra years that need app or website registration. Read the terms before you buy.
