Anker SOLIX C1000 Review (2026): C1000 vs C1000 Gen 2, Specs and Verdict

Affiliate disclosure: This page contains affiliate links. If you buy through them, we may earn a commission at no extra cost to you. That never changes our verdict.

How this review was made: We have not tested the Anker SOLIX C1000 or C1000 Gen 2 ourselves. This is a research-based review built on Anker’s official US product pages, Anker’s own comparison table and its published warranty terms, all checked on October 18, 2026. Runtime figures are our calculations from the published capacity, not measurements. Sources are at the bottom.

Quick answer (TL;DR)

• Buy the C1000 Gen 2 if you’re buying new today. It has 1,024Wh, 2,000W output (3,000W peak), a 49-minute full recharge, a 10ms UPS and weighs 24.9 lb, for $699.99 at time of writing on Anker’s US store.
• The original C1000 (1,056Wh, 1,800W) was listed at $599.99 but sold out on Anker’s US store when we checked. Its one real advantage is that it can take an expansion battery to reach 2,112Wh. The Gen 2 can’t be expanded.
• Best for: CPAP, router, laptop and fridge backup through short outages, plus running a microwave, kettle or space heater from a compact box.
• Skip it if you need all-day fridge backup or want to grow your system; look at a 2kWh unit instead (see our best portable power stations for home backup).

The Anker SOLIX C1000 is one of the most searched portable power stations in the US, and for good reason: it puts a lot of output into a 1kWh, carry-with-one-hand box. But there are now two of them. The original C1000 launched first; the C1000 Gen 2 replaced it with more output, faster charging and a quicker UPS, but dropped expansion. Plenty of listings still mix them up.

This review explains which is which, compares their official specs side by side, works out what they can actually run at 120V, and gives you a clear verdict on who should buy each one.

C1000 vs C1000 Gen 2: Which Is Which?

Anker’s own warranty table and comparison chart make the two easy to tell apart:

If a listing says “1,056Wh | 1,800W,” it’s the original. If it says “1,024Wh | 2,000W,” it’s the Gen 2.

Anker SOLIX C1000 Specs Compared

All figures from Anker’s official US pages. Where Anker’s pages disagree, we show both.

One discrepancy to know about: the original C1000’s product page lists a 2,400W “AC surge output” and describes SurgePad, which Anker says kicks in for heat-generating devices when total output exceeds the rated output. Anker’s newer comparison table lists the original at 3,000W peak. We report both rather than pick one.

What’s New in the C1000 Gen 2

Based on Anker’s published specs, the Gen 2 improves on the original in five ways:

1. More output: 2,000W continuous, up from 1,800W.
2. Faster charging: 49 minutes to 100% with UltraFast (1,600W), versus 58 minutes. Anker says this was the fastest of any portable power station as of April 2025. It also charges from the wall and solar at the same time.
3. Quicker UPS: under 10ms, versus 20ms.
4. Longer rated life: 4,000 cycles to 80%, versus 3,000.
5. Lighter and smaller: 24.9 lb versus 28.44 lb.

The trade-offs: about 32Wh less capacity, and no expansion. Anker’s FAQ says it dropped expansion to save weight and size, and recommends the original C1000 for anyone who needs to add capacity.

A practical note from Anker’s FAQ: UltraFast charging is switched on in the Anker app, works when the battery is above 68°F (20°C) and slows a lot at 32–68°F. Anker also suggests using it only when you need it, to prolong battery life.

What Can the Anker SOLIX C1000 Run?

To estimate runtime, we use the same method as our what size power station guide: runtime = Wh × 0.85 ÷ watts, where 0.85 allows for inverter losses. That gives about 870Wh usable for the Gen 2 (1,024 × 0.85) and about 898Wh for the original (1,056 × 0.85).

Estimates only. Real runtimes depend on the appliance, temperature and battery age. The 100W fridge and 40W CPAP figures match Anker’s example loads on the Gen 2 page, which also lists a 1,000W kettle. A fridge’s compressor cycles on and off, and Jackery puts most modern fridges at 100–400W while running, with startup surges 2–4× higher.

What this tells you: either C1000 easily covers a night of CPAP, Wi-Fi and phone charging. It can carry a fridge through a short outage, roughly the length of a workday. For a full day of fridge plus essentials, you need about 2kWh. Our sizing guide shows how to work out your number, with a 20% safety margin built in.

Charging and Solar

Both versions accept up to 600W of solar, which is high for a 1kWh unit; the Gen 2 is rated to fill up in 1.8 hours at full input. For comparison, Jackery’s Explorer 1000 v2 takes 400W. Anker’s Gen 2 spec table lists 11–28V at up to 8.2A and 29–60V at up to 14.5A, so check your panel’s voltage before connecting.

The Gen 2 lists six ways to recharge. For buying a unit with panels, see our best portable power station with solar panel guide, which compares the C1000 Gen 2 panel bundles ($999.99 with 100W, $1,199.99 with 200W, $1,399.99 with 400W at time of writing) against Jackery and EcoFlow kits.

Home Backup Fit

UPS: the Gen 2’s sub-10ms switchover is quick enough for most routers, modems and many PCs. Anker markets it for CPAP machines and laptops. If you rely on a CPAP or any medical device, confirm with the device maker and your doctor before depending on battery backup.

Output: 2,000W runs most single kitchen appliances. That’s unusual for a 1kWh unit; see our 2000W portable power station guide for how it compares with larger 2,000W-class models.

Safety listings: the original C1000’s page says it’s certified by SGS to UL 1012, UL 1778, UL 1973 and UL 60730.

Storage: Anker’s C1000 FAQ says to turn off outputs when not in use, store it somewhere cool and dry, recharge to 100% if it falls below 30%, and fully charge it once every three months.

Limits: neither version offers 240V or a TT-30 RV outlet, and the Gen 2 can’t grow. For whole-home or circuit-level backup, look at the larger systems in our best portable power stations for home backup roundup.

Pros and Cons

Anker SOLIX C1000 Gen 2

Pros

• 2,000W output (3,000W peak) from a 1kWh, 24.9 lb unit
• 100% recharge in 49 minutes with UltraFast
• Sub-10ms UPS
• 600W solar input, and it can charge from AC and solar at once
• 4,000-cycle LFP battery and 60-month warranty

Cons

• Not expandable
• $0.68 per Wh, more than Jackery’s Explorer 1000 v2 ($0.47)
• UltraFast needs the app and a battery above 68°F

Original Anker SOLIX C1000

Pros

• Expandable to 2,112Wh
• 600W solar input
• Slightly more capacity (1,056Wh)

Cons

• Sold out on Anker’s US store when we checked
• Slower 20ms UPS (per Anker’s table) and lower rated cycle life (3,000)
• Heavier (28.44 lb) and can’t charge from AC and solar at the same time

How It Compares With Rivals

The Jackery is the budget choice. EcoFlow’s DELTA 3 Plus costs about $19 more than the Gen 2 and gives you expansion and more solar input, but less output and more weight. The C1000 Gen 2 has the most output and the fastest recharge of the three, and it’s only about a pound heavier than the Jackery. For the full brand matchups, see Jackery vs Anker and EcoFlow vs Jackery.

Verdict

Based on Anker’s published specs and prices, the Anker SOLIX C1000 Gen 2 is one of the strongest 1kWh power stations you can buy at time of writing. Its 2,000W output, 49-minute recharge and 10ms UPS make it a great fit for apartment backup, CPAP nights and running a kitchen appliance during an outage. It’s not the cheapest per watt-hour, and it won’t grow with you, so plan on a 2kWh unit if you want all-day fridge backup.

Only choose the original C1000 if expansion matters to you and you can find it new from Anker or an authorized seller. At time of writing, it was sold out on Anker’s US store.
