Anker SOLIX C1000 Gen 2 Review (2026)
Updated January 2026
The Anker SOLIX C1000 Gen 2 is the refined follow-up to Anker's popular 1kWh power station. It keeps roughly the same footprint but bumps the inverter to a full 2000W, trims the weight slightly, and shaves the recharge time down to a class-leading 49 minutes. At $699 with a 4.7 rating, it's built for the buyer who wants the most power and the fastest top-up available in the sub-30-pound class.

Key Features
2000W AC output. The jump from 1800W to 2000W continuous is meaningful. It clears the bar for high-draw kitchen appliances, larger power tools, and running two demanding devices at once. Where the original C1000 occasionally had to be babied on the biggest loads, the Gen 2 has comfortable headroom.
1024Wh LFP battery. Capacity is essentially unchanged from the first generation — you're still working with about a kilowatt-hour of long-life lithium iron phosphate. The value here isn't more energy; it's the same energy delivered through a stronger inverter in a lighter, faster-charging package.
1000W AC / 600W solar input. The higher 1000W wall input is what enables the sub-50-minute recharge. Solar input holds at 600W, so a pair of 200-300W panels can keep you topped up during a sunny day off-grid.
49-minute full charge. This is the fastest recharge of any unit in this roundup, and it's the Gen 2's signature party trick. For home-backup use it's transformative: any short window of restored grid power refills the battery almost completely.
Great power-to-weight ratio. At 27.6 pounds delivering 2000W, this is one of the most power-dense stations in its class. That matters every time you carry it from the garage to the car to the campsite.
Real-World Performance
Plan around roughly 870-900Wh of usable energy from the 1024Wh pack after inverter overhead. Divide that by a device's wattage to estimate runtime.
CPAP. At 30-40W without humidification, expect two to three nights per charge. With the heated humidifier running at 60-90W, you'll get roughly a single full night — fine for a weekend, and the near-instant recharge means you can refill during the day.
Camping and RV. A portable fridge averaging 40-50W will run the better part of a day, leaving margin for device charging and lights. The extra inverter headroom over the original also means you can run an induction cooktop or electric kettle for short bursts to cook, which the 1800W first-gen handled with less margin.
Home backup. The Gen 2 is arguably the best small-backup unit here precisely because of the 49-minute recharge. It runs a fridge in cycles, keeps your network and phones alive, and refills faster than any competitor when the grid blinks back. For outages measured in hours, it's ideal; for multi-day outages, capacity is the limiting factor.
Heavy loads. The 2000W/3000W-surge rating starts hair dryers, shop vacs, and compressors without complaint. As with any compact high-output unit, sustained heavy draw will warm it up — see the honest note below.
Off-grid recharging. With 600W of solar input, two 300W panels can put a meaningful dent in the pack in a few hours of good sun, and on a full sunny day you can realistically cover a fridge plus device charging while still net-recharging. That makes the Gen 2 a capable base-camp or overlanding companion despite its modest capacity — you're not limited to the energy you left home with.
Generation-over-generation. If you're weighing the Gen 2 against the original C1000, the differences are all in the right places: 200W more continuous output, a bigger 3000W surge, a faster 49-minute recharge, and a slightly lighter body, all at the same $699. Capacity is the one thing that didn't grow, so the decision really comes down to whether ~1kWh is enough for your use case — if it is, the Gen 2 is the better buy.
Pros & Cons
Pros
- Fastest charging at 49 minutes — nothing else in this class refills faster, which is a genuine day-to-day convenience.
- Compact for 1kWh — the tidy footprint fits easily in a car trunk, closet, or RV cabinet.
- Great power-to-weight ratio — 2000W in a 27.6-pound body is exceptional density.
Cons
- Smaller capacity than 2000Wh options — at ~1kWh it's a bridge unit, not a multi-day off-grid solution.
- Gets warm under heavy load — pushing near 2000W continuously generates heat and fan noise, so it's not the unit to run silently in a bedroom at full tilt.
Who Should Buy It
Buy the Gen 2 if you want the strongest inverter and fastest recharge in a compact ~1kWh station, and you value power and portability over raw capacity. It's the pick for buyers who charge in short windows, carry their unit frequently, or occasionally need to run a demanding appliance the original C1000 would strain against. If you're choosing between the two generations, the Gen 2 is the better unit at the same price.
Skip it if you need to power devices for several days off-grid without a recharge — that's a job for a 2kWh unit. The modest capacity is the only real reason to look elsewhere.
Verdict
The Anker SOLIX C1000 Gen 2 earns a 4.7 / 5. It takes an already-strong platform and improves the two things that matter most day to day — output power and recharge speed — while trimming weight. The only trade-offs are the ~1kWh capacity ceiling and some warmth under maximum load. For anyone shopping the compact power-station class, this is one of the smartest buys available.
