Best forBudget-focused storm preppers who want maximum stored energy per dollar and can tolerate fan noise.

The budget king of the 1kWh class - a perpetual marketplace best-seller with a review count nothing else touches. You get more capacity (1,152Wh) than the Anker or EcoFlow rivals, 1800W output with a 2,700W Power Lifting mode for heaters and kettles, and a wireless charging pad, usually for under $450. Owners are clear-eyed about the trade-offs: the fan runs early and often, including during wall charging in Silent mode. The 12V DC port is a regulated but weak 10A, there's no expansion support, and at 35.3 lbs it's a full 10 lbs heavier than the Jackery. But for a storm-prep box that lives in a closet and runs the fridge when needed, the price-per-Wh math has kept it the default recommendation for budget buyers since 2023.

Summarised from owner discussions and forums

Owner insights

The AC180 is a 1kWh station owners lean on when the power goes out. A Florida owner ran the fridge, coffee, fans and lights through Hurricane Milton, two long-haul truckers run coffee machines and microwaves off theirs on the road, a camper powers Starlink with it, and an owner with a big Anker station keeps one as the portable unit that goes wherever an outlet is missing.

The solar input caps at 10A and 60V, so parallel panels get clipped. Small AC loads are inefficient: an owner running a 48W fan got 525Wh out before stopping at 3% and blamed inverter losses at low load, while another explanation offered was BMS calibration, which the manual addresses with a full cycle every six months. The fan comes on during wall charging even in Silent mode. Failures turn up too, from charging-rate drops to a unit that died outright, and support works through slow email back-and-forth, though one owner whose unit failed after a year was offered repair, a refurbished swap, or buying a new unit and being refunded once the dead one arrived.

Storm prep and camping on a budget are its territory, as long as 1,152Wh is enough and will stay enough. The EcoFlow DELTA 2 has sold for the same $450 and can take an extra battery, while Bluetti's own Elite 100 V2 trades about 128Wh of capacity for 10 fewer pounds. Anyone who expects to want more capacity later is better served by an expandable unit than by the DIY packs and B230 cabling AC180 owners have tried.

What owners like

+Carried one Florida owner, who bought it right after Helene, through Milton: coffee, the fridge and every device charged, a loan to friends and neighbors as power trickled back, then fans and lights when the power dropped again
+Survives hard daily use: a long-haul trucker and a colleague have run coffee machines, microwaves, laptops and air fryers off theirs since January, and it has shrugged off knocks and spilled drinks
+Sale pricing has landed at $450-460 new, in October 2024 and February 2025, and refurbished units have been offered at $380-419; one Prime Day deal post set it against the DELTA 2 at the same $450
+Works as the grab-and-go unit: an Anker F3800 owner carried it downstairs to open a garage door and run a circular saw for cutting plywood outside, and another ran Starlink on it while birding in a remote part of the eastern Sierra
+Easy to keep topped up from a small inverter generator: an owner boosted it from a Predator 2000 through a hurricane outage, and a buyer who paired it with a Honda EU2200i asked whether the Honda can recharge it and plans to cycle between the two
+Power Lifting mode stretches to 2,700W for heating elements such as kettles, while staying off compressors like fridges and air conditioners
+One jobsite crew got a dead scissor lift moving again after about 10 minutes of charging from it

Common complaints

−No expansion port: an owner built a DIY pack in a case on the solar input, and another who chained a B230 found it took about $200 of extra cables and said that at full price he would rather have had two separate stations, though he bought both at a heavy discount
−Solar input is held to 10A and 60V, so two 240W panels in parallel at about 40V get capped by current, and owners with low-voltage panels debate series wiring to get more through
−Small AC loads waste a large share of the battery: a 48W box fan ran 10 hours 45 minutes and drew only 525Wh, and an owner-cited 24-hour test put the inverter's no-load draw near 11W
−The fan runs during wall charging even in Silent mode, which one new owner found much louder than expected on the first charge, and another hears electrical noise through speakers when it kicks in
−Scattered charging faults: turbo wall charging that falls from about 1,100W to 260W, car charging that cycles down to zero and back, and a unit that would not charge past 57%
−Warranty support runs by email and can drag: one unit died after seven months of monthly checks and the local FedEx refused the hazmat return, and another began shutting down at 50%, then got worse after a support-pushed BMS update
−Bluetti now pitches the Elite 100 V2 as its successor, with 1,024Wh in 25.3 lbs for $399 at launch against the AC180's 1,152Wh in 35.3 lbs

Questions owners ask

Can I leave the AC180 plugged in and use it as a UPS for my computer and router?

Owners do this for computers and networking gear, and one runs two AC180s on the household fridges behind transfer switches so they only carry the fridge when the grid drops. A shopper sizing one for a gaming PC worried whether its roughly 20ms switchover is fast enough. One commenter notes the manual asks for a full battery cycle every six months.

Why do parallel panels get clipped on the AC180?

The input tops out at 60V and 10A. One owner's two 240W panels wired in parallel at about 40V were held to 10A and peaked at 400W. Owners with lower-voltage panels ask about series wiring instead, keeping the combined open-circuit voltage under 60V.

Is there an expansion battery for the AC180?

No. The AC180 has no expansion port. A B230 can charge it through the input, but an owner found that took about $200 of cables and is not plug and play, and another built a DIY pack in a case with its own fans, a thermostat and XT90 connectors.

Why did my AC180 deliver far less than 1,152Wh?

Low AC loads are one reason: an owner's 48W fan test produced only 525Wh, and their own breakdown put the inverter at about 60% efficient at that load. Another owner suggested the BMS might be out of calibration, since their own unit sat at 1% for about 10 minutes under load on its first full discharge and read more accurately after a few cycles. Another tip is running small devices from the DC or USB ports to avoid the inverter's idle draw.

AC180 or EcoFlow DELTA 2?

Both have sold for about $450 on Prime Day, and deal posts set them side by side. The AC180 gives you more capacity, 1,152Wh against 1,024Wh, while the DELTA 2 can take an extra battery. One full-time van owner started shopping for a DELTA 2 after a significant reliability problem with the AC180.
