The Anker Solix C1000 Gen 2 is the successor to one of the best value power stations we have reviewed. It charges faster, weighs less, and pushes more watts than the original C1000, all while dropping to lower street prices. But Anker made tradeoffs to get there: no expansion battery, no LED light, and one fewer AC outlet. Whether those cuts matter depends entirely on how you plan to use the unit.
If you need the short version: buy the Gen 2 if you want the fastest-charging 1kWh power station on the market at the best price. Keep the original C1000 if expandability is non-negotiable. And compare both against the EcoFlow Delta 3 Plus if you have a bigger budget and want quieter operation.
Design and Build Quality
Anker redesigned the C1000 from scratch for Gen 2. The external dimensions shrunk 14% compared to the original, and the weight dropped from 30.9 lbs to 24.9 lbs. That 6 lbs difference is noticeable every time you lift it. The unit now fits comfortably in one hand by the integrated handle, which locks upright and folds flush when stowed.
The body uses the same charcoal gray finish as the rest of Anker's Solix line. Build quality remains excellent: tight panel gaps, no flex when gripped, and rubber feet that actually grip smooth surfaces. The display sits front and center with real-time input/output wattage, battery percentage, and estimated runtime. It is easy to read in direct sunlight.
Port layout changed from the original. All five AC outlets now sit on the front face alongside the USB ports. The car port moved to the side. Every port has a rubber dust cover. The AC outlet spacing is tight, so bulky transformer plugs can block adjacent sockets. Standard three-prong plugs fit side by side without issue.
One notable omission: the built-in LED floodlight from Gen 1 is gone. If you camp regularly and relied on that light, you will need a standalone lantern. For home backup users, this will not matter.
Charging Performance: 49 Minutes Flat
The headline upgrade is charging speed. Anker's HyperFlash technology pushes up to 1,600W of AC input in UltraFast mode, filling the 1,024Wh battery from dead to full in 49 minutes. Anker earned a Guinness World Record for this in August 2025, claiming the title of fastest-recharging 1kWh portable power station.
In practice, the unit draws closer to 1,200W during most of the charge cycle, ramping up toward the end. The standard charging mode caps input at 1,200W and completes in about 60 minutes. Standard mode generates less heat and is better for everyday use when you do not need maximum speed.
For context, the original C1000 takes 58 minutes for a full charge. The EcoFlow Delta 3 Plus needs about 56 minutes. The Gen 2's 49-minute time is genuinely best-in-class for a 1kWh unit.
Solar Charging
Solar input accepts up to 600W at 11-60V through an XT60i connector. With 400W of panels on a clear day, expect a full charge in roughly 2.5 hours. With a 200W bifacial panel (Anker sells a matched one), count on 3.5 to 4 hours in good conditions. The MPPT controller is efficient, tracking above 97% in our measurements.
The Delta 3 Plus accepts similar solar wattage but reaches full charge slightly faster due to its higher maximum solar acceptance in optimal conditions. In practical terms, both units charge at about the same speed with a typical 400W panel array.
Car Charging
The 12V car input charges at approximately 100W, meaning a full charge takes around 10 hours. This is standard for the category. For road trips, it is best used for topping up rather than full charges. Anker also sells a separate alternator charger accessory that charges significantly faster while driving.
Output and Ports
The Gen 2 bumps continuous output from 1,800W to 2,000W, with SurgePad handling peaks up to 3,000W. That extra 200W matters for borderline appliances like space heaters, hair dryers, and larger power tools that occasionally tripped the original C1000.
Port Breakdown (10 Total)
| Port | Count | Max Output |
|---|---|---|
| AC Outlets (120V, NEMA 6-20) | 5 | 2,000W total |
| USB-C (PD 3.1) | 2 | 140W each |
| USB-C | 1 | 15W |
| USB-A | 1 | 12W |
| Car Socket (12V) | 1 | 120W |
The dual 140W USB-C ports are a genuine upgrade. They can fast-charge a MacBook Pro at full speed, something the original C1000's USB-C ports could not do. If you carry a USB-C laptop, this alone justifies the upgrade.
The AC outlets deliver clean sine wave power. The 2,000W continuous rating handled every appliance we threw at it during testing, including a 1,500W electric kettle, a circular saw with startup surges, and a full-size blender. The 3,000W surge capacity means motor-start loads from refrigerators and compressors are well within range.
UPS Functionality
The Gen 2 retains UPS (uninterruptible power supply) capability with sub-10ms switchover. Plug sensitive electronics into the AC outlets, keep the unit plugged into the wall, and it acts as a battery backup during outages. The switchover is fast enough that computers, routers, and NAS drives stay running without rebooting. This makes the Gen 2 a solid choice for a home office backup solution.
Battery Chemistry and Longevity
The Gen 2 uses LiFePO4 (lithium iron phosphate) cells rated for 4,000 cycles to 80% capacity. That is a meaningful jump from the original C1000's 3,000-cycle rating. At one full cycle per day, the battery should last over 10 years before noticeable degradation.
Anker's InfiniPower temperature management system adjusts charge rates based on internal and ambient temperature. This protects the cells during UltraFast charging, which generates more heat than standard mode. The operating temperature range is -4F to 104F for discharge and 32F to 104F for charging.
Anker backs the Gen 2 with the same 5-year warranty as the original. Given the improved cycle rating, the warranty covers a smaller fraction of the battery's expected life, which is a good sign for long-term value.
What the Gen 2 Lost: Expansion
The original C1000 could pair with a BP1000 expansion battery ($599) to double capacity to 2,112Wh. The Gen 2 cannot expand at all. This is the single biggest functional downgrade.
If your use case demands more than 1,024Wh, you have two options: buy a second standalone unit and run them independently, or choose a competitor that supports expansion. The EcoFlow Delta 3 Plus expands up to 5kWh with additional batteries. The Anker Solix F2000 provides 2,048Wh in a single unit if you just need more capacity from Anker.
Smart App Features
The Anker app connects via both Wi-Fi and Bluetooth (Gen 1 was Bluetooth-only). Wi-Fi means you can monitor and control the unit from anywhere in your house, not just within Bluetooth range.
App features include:
- Real-time input/output monitoring with graphs
- Charge rate selection (standard vs. UltraFast)
- Battery charge limit (cap at 80% for maximum lifespan)
- Scheduled charging for off-peak electricity rates
- Firmware updates
- UPS mode configuration
- Time-of-Use (TOU) mode for smart energy management
The app is responsive, connects reliably, and provides more granular control than EcoFlow's app in some areas (charge scheduling, in particular). Jackery's app still lags behind both in functionality and polish. First-time Bluetooth pairing can occasionally take two tries, but Wi-Fi connection is seamless once configured.
Real-World Use Cases
Home Backup
The 1,024Wh capacity keeps a full-size refrigerator running for roughly 5 to 6 hours, a Wi-Fi router and modem for 3+ days, or a laptop for 8+ hours of continuous work. The UPS mode means you can leave it plugged in behind your desk or home office setup for always-on protection.
For extended outages, the 49-minute charge time is a game changer. If power comes back briefly, you can refill the entire battery in under an hour. Pair with a 200W solar panel and you have indefinite daytime power for essential devices.
Camping and Outdoors
At 24.9 lbs, the Gen 2 is light enough for car camping without requiring two people to carry it. A weekend trip running a mini-fridge (60W), phone charging, and LED lights is well within the 1,024Wh capacity. The 2,000W output means you can run a portable coffee maker, blender, or even a small electric grill if you want hot food at camp.
The missing LED light is a minor annoyance for campers. Pack a headlamp or lantern to compensate.
Remote Work and Craft Shows
Running a MacBook Pro and external display draws about 120W, giving roughly 7 to 8 hours of work time per charge. The 140W USB-C ports mean you can charge your laptop directly without an AC adapter, saving weight and outlet space. For craft shows, the 2,000W output handles laser cutters, heat presses, air purifiers, and payment terminals simultaneously.
CPAP and Medical Devices
A CPAP machine at 30W draws roughly 1.5% of the battery per hour, translating to about 3 full nights on a single charge. The pure sine wave output is safe for sensitive medical electronics. If you travel with a CPAP, read our dedicated CPAP battery backup guide for sizing recommendations.

Value Assessment
At retail $799, the C1000 Gen 2 already undercuts the Delta 3 Plus by $200 while delivering faster charging and higher output. But the real story is street pricing. Anker has been aggressive with discounts since launch, and the Gen 2 regularly appears at $449 or less at Amazon, Best Buy, Home Depot, and Lowe's. At that price, it is the best value per watt-hour in the 1kWh class by a wide margin.
The cost-per-cycle math is compelling. At $449 with 4,000 cycles, each full charge costs about $0.11. Even at the full $799 retail, that drops to $0.20 per cycle. Either way, the electricity to charge it (roughly $0.10 per charge at average US rates) will cost more over the unit's lifetime than the hardware itself.

Who Should Buy the Gen 2
- Upgraders from the original C1000 who do not use the expansion battery
- First-time buyers who want the fastest charge time and lowest price per watt
- Home backup users who want UPS protection with quick-refill capability
- Campers and road trippers who value lighter weight and compact size
- USB-C laptop users who need 140W fast charging from a power station
Who Should Skip It
- Users who need expandable capacity: the Gen 2 caps at 1,024Wh with no expansion option. Look at the Delta 3 Plus or the original C1000
- Noise-sensitive users: the fans are loud during fast charging and high-load output. The Delta 3 Plus is noticeably quieter
- Users who rely on the built-in light: campers who used the original C1000's LED should factor in a replacement lantern
Our Verdict
The Anker Solix C1000 Gen 2 earns a 4.5/5. It pushes the 1kWh category forward with record charging speed, lighter weight, and more output power, all at a lower price than the competition. The tradeoffs (no expansion, no light, louder fans) are real, but they will not matter to most buyers.
If you buy one power station in 2026 and your budget is under $800, this is the one to beat. The frequent sales below $500 make it an even easier recommendation.
