Anker’s SOLIX C1000 Gen 2 and BLUETTI’s Elite 100 V2 both pack a 1,024Wh lithium iron phosphate battery into a carry-by-hand box of about 25 pounds, but Anker’s model outputs 2,000W and refills from the wall in 49 minutes, while BLUETTI’s accepts up to 1,000W of solar, according to each company’s published specs. They’re the two most direct rivals in the 1kWh class right now. The better buy depends on whether you recharge mostly from an outlet or from panels.

Wall charging: Anker’s clear edge
Anker says the C1000 Gen 2 goes from empty to full in 49 minutes at 1,600W once you switch on UltraFast charging in the Anker app. Without it, the AC input is 1,200W. Anker’s own advice is to use UltraFast only when necessary to prolong battery life.
BLUETTI’s Elite 100 V2 tops out at 1,200W in Turbo mode, reaching 80% in about 45 minutes. Its default Standard mode and app-only Silent mode both charge at 600W and take about 2 hours. If you’re topping up before a storm hits or between job sites, the Anker finishes first.
| Scenario | C1000 Gen 2 | Elite 100 V2 |
|---|---|---|
| Fastest wall mode | ~49 min to 100% (1,600W) | ~45 min to 80% (1,200W) |
| Battery-friendly mode | 1,200W | 600W, about 2 hrs |
Solar charging: BLUETTI’s clear edge
The Elite 100 V2 accepts up to 1,000W of solar at 12–60V and 20A, through a cable with two MC4 pairs that combine in parallel. BLUETTI’s manual example uses two 200W (20V/10A) panels in series on each pair, which gives four panels and 800W of rated input.
The C1000 Gen 2 accepts 600W at up to 60V. Anker caps current at 8.2A below 28V and 14.5A from 28 to 60V, and recommends six 100W, three 200W, or a 400W plus 200W panel to hit 600W. Anker quotes a 1.8-hour full solar recharge at 600W.
Worked example: one sunny day
Estimates assume about 5 peak sun hours and roughly 75% of panel rating actually reaching the battery after heat, angle and wiring losses.
- Anker with 600W of panels: 600 × 0.75 × 5 ≈ 2,250Wh, more than enough to refill 1,024Wh, with the station limited by its 600W input.
- BLUETTI with 800W of panels: 800 × 0.75 × 5 ≈ 3,000Wh potential, so it refills sooner in the day and keeps charging in weaker morning and evening light.
- Cloudy day, 2 effective sun hours: Anker ≈ 900Wh; BLUETTI ≈ 1,200Wh, the difference between a full and nearly full battery.
If you camp off-grid for days, BLUETTI’s extra 400W of headroom matters more than Anker’s wall speed. My MPPT vs PWM explainer covers what’s happening inside both chargers.
Output and ports
Anker’s 2,000W continuous rating gives it 200W more than BLUETTI’s 1,800W. In practice that covers loads like a 1,800W space heater with room for a phone charger, or a microwave plus a coffee grinder. BLUETTI’s Power Lifting mode runs resistive loads rated 1,800–2,700W, such as kettles and hair dryers, but its manual notes the actual output stays at 1,800W, so the appliance runs at reduced power.
For laptops, the C1000 Gen 2 has two 140W USB-C ports, while the Elite 100 V2 has one 140W and one 100W. Both include a 12V car outlet. BLUETTI adds two DC5521 barrel ports (12V, 8A total), handy for small 12V gear.
Runtime worked examples
Both stations hold 1,024Wh, so runtimes are nearly identical. Estimates assume 85% usable after inverter losses.
| Load | Draw | Runtime on either (estimate) |
|---|---|---|
| CPAP without humidifier | ~40W | ~21 hrs |
| Starlink Mini | ~25–40W | ~22–35 hrs |
| Full-size fridge (average) | ~150W | ~5.8 hrs |
| 1,000W microwave | ~1,000W | ~52 min |

Portability and build
Weights are within half a pound of each other. The Elite 100 V2 is shorter at 12.6 inches long versus 15.1 inches, which helps in a car trunk. Anker sells the C1000 Gen 2 bundle with an IP54 water-resistant cover, according to its Amazon listing, which protects it from rain at a campsite. BLUETTI rates the Elite 100 V2 at 50dB max noise in its manual.
Home backup use
Both switch to battery in about 10 ms, quick enough for most routers, modems and desktop PCs. Anker says the C1000 Gen 2 can charge from grid and solar at the same time with solar prioritized; BLUETTI’s app offers UPS modes, including one that charges from the grid to a set level and then switches to solar. Neither expands with an extra battery, so for longer outages consider a 2kWh station like those in my Delta 3 Max vs Anker SOLIX S2000 comparison.
Who should buy which
- Anker SOLIX C1000 Gen 2: mostly wall charging, fastest refill, 2,000W output, two 140W USB-C ports.
- BLUETTI Elite 100 V2: solar-first camping and van trips, up to 1,000W of panels, shorter footprint, extra 12V barrel ports.

FAQ
Which charges faster, C1000 Gen 2 or Elite 100 V2?
From the wall, the C1000 Gen 2 (full in 49 minutes with UltraFast). From solar, the Elite 100 V2 accepts more power: 1,000W vs 600W.
Are they the same capacity?
Yes, both are rated at 1,024Wh.
Can either add an expansion battery?
Anker says the C1000 Gen 2 doesn’t support expansion and points buyers to the original C1000 instead.
Which has more AC power?
The Anker: 2,000W continuous and 3,000W peak, versus 1,800W for BLUETTI.
Do both work as a UPS?
Yes, with about 10 ms switchover on each.
What’s the max solar voltage?
60V for both, so keep series strings under that open-circuit voltage.
Bottom line
These two are evenly matched on capacity, weight and cycle life. The C1000 Gen 2 wins on wall-charging speed and raw output; the Elite 100 V2 wins on solar input and footprint. Pick by how you’ll recharge it most often.
