Anker SOLIX C1000 Gen 2 Review: 49-Min Charging Beast
The C1000 Gen 2: What Actually Changed
The original Anker SOLIX C1000 launched at $999. The Gen 2 arrives at $499 with meaningfully better specs across almost every metric — 200W more continuous output (2,000W vs 1,800W), 33% faster charging, 1,000 additional battery cycles (4,000 vs 3,000), and a Guinness World Record for the fastest recharging portable power station in its class as of August 2025. Cutting price in half while improving specs is genuinely unusual in this category.
Key Specifications
Capacity: 1,024Wh LFP (LiFePO4) · AC output: 2,000W continuous / 3,000W peak · AC input (HyperFlash): 1,600W → 0–100% in 49 minutes · Solar input: 600W max (XT60i, 11–60V) · Battery cycles: 4,000 to 80% capacity · UPS switchover: 10ms · Weight: 24.9 lbs (11.3 kg) · Ports: 5× AC, 3× USB-C (140W each), 1× USB-A, 1× car port · Price: ~$499 USD (regularly on sale $349–$379)
HyperFlash Charging: The Standout Feature
49 minutes from flat to full is extraordinary at this capacity class. EcoFlow's Delta 2 charges in approximately 50 minutes — effectively identical. Jackery's Explorer 1000 Pro takes 1.8 hours. Bluetti AC180 takes approximately 55 minutes. Anker and EcoFlow have essentially tied for the fastest 1kWh charging in 2026, and both have left Jackery and Bluetti behind at this spec.
One important note: HyperFlash must be activated through the Anker app, and Anker specifies using their supplied AC charging cable — third-party cables may not sustain the 1,600W input required. This is a minor friction point but worth knowing before you expect instant 49-minute performance on day one.
2,000W Output: What It Unlocks
The 2,000W continuous output with 3,000W surge covers the overwhelming majority of household appliances and camping loads. Running simultaneously on AC: a mini-fridge (150W) + laptop (65W) + LED lighting (50W) + phone charging (30W) draws approximately 295W — the C1000 Gen 2 handles this load for approximately 3 hours before reaching 20% battery. Run the AC outputs harder — a 1,500W space heater draws down the 1,024Wh in approximately 40 minutes at that load, which is the honest reality of high-draw appliances on a 1kWh station regardless of brand.
What the 2,000W ceiling opens that 1,000–1,800W units can't handle: most microwave ovens (800–1,200W), window air conditioners under 1,800W, and power tools under 2,000W. The 3,000W surge handles high-inrush motor startup loads.
Battery Longevity: 4,000 Cycles
LFP chemistry rated at 4,000 cycles to 80% capacity means approximately 11 years of daily cycling before hitting the 80% threshold — and the battery continues functioning below 80%, just with reduced runtime. This is the best longevity rating in the 1kWh class. Anker's InfiniPower technology (their branding for the third-generation LFP cell management system) claims a 10-year lifespan guarantee backed by the 5-year warranty — the longest standard warranty in the portable power station category.
10ms UPS Mode: Silent Home Backup
The 10ms transfer time means your devices — router, NAS, desktop computer, medical equipment — experience effectively seamless power during a grid dropout. Most UPS (uninterruptible power supply) devices switch in 20–30ms; 10ms is below the threshold where most electronics register a power interruption. For households where an internet router going offline even briefly is a problem, the C1000 Gen 2's UPS mode is a legitimate differentiator over standard "backup mode" power stations that switch in 100–300ms.
Solar Charging: 600W Input
The XT60i solar port accepts up to 600W at 11–60V. With a single 200W panel in good sun, you're looking at a full charge in approximately 6 hours. Two 200W panels in parallel (within the 600W ceiling) bring this to approximately 3 hours. This solar input is competitive with EcoFlow's Delta 2 (500W) and meaningfully higher than Jackery's Explorer 1000 Pro (400W). The XT60i connector requires an adapter for MC4 panels — Anker includes a cable in the box for most setups.
Real-World Runtime Estimates
Mini-fridge (100W average): ~8–9 hours · CPAP machine (30W, no humidifier): ~28 hours · Laptop + phone + lights (150W): ~5.5 hours · Window AC (900W): ~55 minutes · 50" LED TV (80W): ~10 hours · Electric blanket (50W): ~16 hours
C1000 Gen 2 vs EcoFlow Delta 2: The Real Competition
These two units are the closest competitors in the 1kWh class at this price tier:
Charging speed: Near-identical (49 min C1000 Gen 2 vs ~50 min Delta 2). Tie.
AC output: Delta 2 wins (1,800W vs C1000 Gen 2's 2,000W — wait, C1000 Gen 2 actually wins here at 2,000W vs Delta 2's 1,800W).
Solar input: C1000 Gen 2 leads (600W vs Delta 2's 500W).
Battery cycles: C1000 Gen 2 leads (4,000 vs Delta 2's 3,000).
Weight: C1000 Gen 2 is slightly heavier (24.9 lbs vs ~33 lbs for Delta 2 — actually Delta 2 is heavier at 33 lbs / 15kg vs C1000 Gen 2 at 24.9 lbs / 11.3kg — C1000 Gen 2 wins on weight).
Warranty: Anker leads (5 years vs EcoFlow's 2 years + extended).
Price: Near-identical ($499 C1000 Gen 2 vs $399–$449 Delta 2 at regular pricing, Delta 2 edges cheaper).
The honest result: the C1000 Gen 2 is the better-specced unit. The Delta 2 is usually slightly cheaper. If you can get either at sale pricing, choose based on which ecosystem (Anker vs EcoFlow) you prefer for future expansion.
Who Should Buy the C1000 Gen 2
Buy it if: you want the fastest-charging 1kWh station under $500 with the longest warranty available, you prioritise LFP battery longevity and 4,000 cycles, or the 10ms UPS mode for home backup is genuinely important to you (router, NAS, medical equipment). Also the clear choice if you already own Anker SOLIX ecosystem products and want a companion unit.
Consider alternatives if: you want the absolute lowest price (EcoFlow Delta 2 often undercuts on sale), you specifically need 1,800W+ output from a lighter unit (the EcoFlow Delta 2 at 15kg is heavier, but Delta 2 Max at 1,024Wh... the C1000 Gen 2 is actually the lighter option at 11.3kg), or you need expandable capacity (C2000 Gen 2 supports expansion; C1000 Gen 2 does not natively).
The Verdict
The Anker SOLIX C1000 Gen 2 is one of the best-value 1kWh power stations available in 2026. At $499 (and regularly on sale at $349–$379), it delivers genuinely excellent specifications: record-fast 49-minute charging, 2,000W output, 4,000-cycle LFP battery, and Anker's class-leading 5-year warranty. The competition from EcoFlow's Delta 2 is real and close, but the C1000 Gen 2 wins on output power, battery cycles, warranty, and weight while matching EcoFlow on charging speed.

Frequently Asked Questions
How fast does the Anker SOLIX C1000 Gen 2 charge?
The C1000 Gen 2 charges from 0% to 100% in 49 minutes using HyperFlash mode at 1,600W AC input. HyperFlash must be activated through the Anker app, and Anker recommends using their supplied AC charging cable for best results. This makes it the Guinness World Record holder for the fastest recharging 1kWh portable power station as of August 2025.
Can the Anker SOLIX C1000 Gen 2 power a refrigerator?
Yes — a standard mini-fridge drawing 100W average runs for approximately 8–9 hours on the C1000 Gen 2's 1,024Wh battery. A larger full-size refrigerator drawing 150–200W runs for 4–6 hours. The C1000 Gen 2's 2,000W continuous output handles refrigerator startup surge currents without issue.
Is the Anker SOLIX C1000 Gen 2 worth it vs the original C1000?
The C1000 Gen 2 is significantly better than the original on every meaningful metric: it costs half as much ($499 vs $999 original MSRP), delivers 200W more continuous output, charges 33% faster (49 min vs 73 min), and adds 1,000 more battery cycles (4,000 vs 3,000). The Gen 2 is the clear choice if you're choosing between the two.
Does the Anker SOLIX C1000 Gen 2 have a UPS mode?
Yes — the C1000 Gen 2 includes a UPS (Uninterruptible Power Supply) mode with a 10ms switchover time. When connected to wall power and a device, it can switch to battery power in 10ms during a grid outage — fast enough that most electronics don't register the interruption. This makes it useful for protecting routers, NAS devices, and medical equipment like CPAP machines during power outages.
