Three 120/240 V home-backup power stations from $2,599.99 to $3,149. The Jackery holds the most energy per dollar; the cycle ratings that decide how long it lasts are measured to three different finish lines.
PeakLoadout finding
At makers' prices on 20 October 2026, the Jackery Explorer 5000 Plus costs $0.62 per watt-hour against $0.68 for the Anker F3800 Plus and $0.68 for the EcoFlow DELTA Pro 3, but Jackery rates its 4,000 cycles to 70% capacity, EcoFlow to 80%, and Anker states no end point for its 3,000+.
They solve the same problem; four numbers separate them:
The Jackery, at $0.62 per Wh of rated capacity. The Anker comes second at $0.68 only because of a $400 code Anker applies automatically at checkout; at its $2,999.99 list price it is the most expensive per Wh of the three, at $0.78. All three prices are promotional and dated, which is why every figure on this page carries its read date.

A five-year warranty is only as good as the company behind it for five years; when Rad Power Bikes went bankrupt, owners of bikes bought before the cutoff were left to file a bankruptcy claim instead of a warranty claim (how that played out).
The ratings cannot say, because they stop at different places. A cycle rating counts full charges until the battery falls to a stated share of its original capacity. EcoFlow stops counting at 80% and Jackery at 70%, so Jackery's 4,000 cycles describe a battery that has given up 30% of its capacity, against EcoFlow's 20%. Anker's "3,000+ cycles" names no end point at all, which makes it impossible to place on the same line.
If you divide price by the energy each rating promises (watt-hours times cycles), the best cases are 15.62 cents per stored kWh for the Jackery, 17.08 for the EcoFlow and 22.57 for the Anker. The Jackery's lead there comes partly from counting further down the fade curve. Across 32 listings, cheap-looking lifetime storage tracks thin cycle disclosure; the disclosure index draws it.
In full sun at maximum input, all three refill in under two hours, as their pages say. That maximum assumes 6.5 to 10 panels of 400 W, which few homes have. On one 400 W array at a realistic 75% of rating, a full refill takes 12.8 to 16.8 hours of sun, or 2.6 to 3.4 days. EcoFlow adds that its 2,600 W figure comes from "experimental results under optimal conditions".
EcoFlow's, most simply: the page describes "a comprehensive 10ms UPS". Jackery's listing promises a "0ms Power Transition". Anker's spec table gives 20 ms, on the three leftmost outlets only, with a bypass limit of 1,440 W, so it covers a desk and a router rather than a whole circuit. None of the three listings names UL 1778, the standard for uninterruptible power supplies; a computer that reboots on a 20 ms gap needs a true UPS in between.
For the most stored energy per dollar, the Jackery; for the clearest battery rating and the lightest unit, the EcoFlow; for the lowest entry price, the Anker while its code runs.
Three other makers sell 120/240 V units in the same class, each read on its own US store on 20 October 2026:
Every unit of 2 kWh or more we read, ranked by price per watt-hour, is in our home-backup buying guide.
Size the outage before you compare units. A refrigerator whose EnergyGuide label reads 500 kWh a year uses about 1,370 Wh a day, so a 4 kWh station runs it alone for about two and a half days after inverter losses, and less with anything else plugged in. The worksheet below is the arithmetic we use.
1. List what must run in an outage and its daily energy: fridge: the kWh per year on its yellow EnergyGuide label / 365 (a 500 kWh/yr label = about 1,370 Wh a day) everything else: watts x hours per day 2. Add them up -> watt-hours per day 3. Divide by 0.85 (inverter losses) 4. Multiply by the days you want to cover 5. Check the biggest single load against continuous AC output, and any motor (fridge, well pump) against surge output 6. If you will recharge from solar: Wh per day / (panel W x 0.75 x 5 h) = how many panel watts keep you level
Every spec was read on each maker's US product page in a browser on 20 October 2026, from the rendered spec table rather than the product feed, and prices from the same pages. Price per watt-hour is the price divided by rated capacity. Best-case storage cost divides the price by rated capacity times rated cycles, assuming every cycle delivers full capacity. Solar refill divides capacity by solar input; the 400 W array case assumes 75% of panel rating and 5 peak-sun hours a day, and ignores conversion losses. We have not tested these units.

It depends on the job. On 20 October 2026 the Jackery Explorer 5000 Plus held the most energy per dollar (5,040 Wh for $3,149, $0.62 per Wh) and the highest output. The EcoFlow DELTA Pro 3 is the lightest at 113.54 lb and the only one rated to 80% capacity. The Anker F3800 Plus was cheapest at checkout at $2,599.99 with a $400 code.
EcoFlow says the DELTA Pro 3 retains 80% of its capacity after 4,000 cycles, on an LFP battery. Jackery rates the Explorer 5000 Plus at 4,000 cycles to 70%, and Anker rates the F3800 Plus at 3,000+ cycles without an end-of-life capacity.
Partly. Anker's spec table gives a 20 ms switching time on the three leftmost outlets, with a bypass limit of 1,440 W. The other outlets are not on the UPS path.
At its 4,000 W maximum solar input, about 1.3 hours of full sun from empty (Jackery says 1.7). On a single 400 W array delivering 75% of its rating it takes about 16.8 hours of sun, roughly 3.4 days at 5 peak-sun hours a day.
EcoFlow DELTA Pro 3 113.54 lb, Jackery Explorer 5000 Plus 134.5 lb and Anker SOLIX F3800 Plus 136.7 lb, all on wheels. Per kWh of capacity the Jackery is lightest (26.7 lb) and the Anker heaviest (35.6 lb).
The Jackery Explorer 5000 Plus is the most stored energy per dollar and the most output, but its cycle rating counts further down the fade curve and its listing does not state a warranty term. The EcoFlow DELTA Pro 3 costs more per watt-hour and says the most about its battery. The Anker F3800 Plus is the cheapest at checkout while its code lasts. Size your outage first, then compare on the numbers that are measured the same way.
