Buy the Anker SOLIX C1000 Gen 2 for most uses: it supplies 2,000 W instead of 1,800 W, has three 140 W USB-C ports, a published 49-minute full charge and a 5-year warranty. Buy the Bluetti Elite 100 V2 if you'll recharge mainly from solar, since it accepts 1,000 W of panels to the Anker's 600 W. Both hold 1,024 Wh of LiFePO4, switch over in 10 ms, weigh about 25 lb and take no extra batteries, so they run the same devices for the same time.

Why pick the Anker SOLIX C1000 Gen 2?
It's the stronger all-rounder. 2,000 W continuous with a 3,000 W surge handles a microwave or a coffee maker alongside a fridge's running load, and Anker counts five AC outlets in its port total. Three USB-C ports at up to 140 W charge 16-inch laptops, and there's a USB-A port and a car outlet. Anker lists a full wall charge in 49 minutes at 1,600 W with UltraFast mode switched on in the app and the cells above 20 °C; normal AC charging is 1,200 W. It's rated for 4,000 cycles to 80%, carries a 5-year warranty and weighs 24.9 lb.
Not for you if: solar is your main recharge (600 W is its ceiling) or you want to add a battery later, which it can't do.
Why pick the Bluetti Elite 100 V2?
For solar. It accepts up to 1,000 W at 12–60 V and 20 A, unusually high for a 1 kWh unit, so with about 1,430 W or more of rated panels it can refill from empty in roughly one hour of peak sun. Two 140 W USB-C ports, two USB-A ports and a car outlet cover most devices, wall charging reaches 0–80% in 45 minutes at 1,200 W, and it's rated for 4,000 cycles to 80%. It weighs 25.3 lb.
The rest of its spec sheet is a step behind. It supplies 1,800 W. Its 2,700 W surge comes from a comparison table and matches its Power Lifting figure, and its four AC outlets are worked out from the total port count, so we mark both as unconfirmed. The page we used doesn't state a warranty term, which costs it points in our engine; check it at purchase. No native expansion is documented.
Not for you if: you mostly charge from the wall, or you need a published warranty term before you buy.
How long does each run the same devices?
| Load (typical daily use) | C1000 Gen 2 | Elite 100 V2 |
|---|---|---|
| Top-freezer fridge | 13–16 h | 13–16 h |
| Fridge + Wi-Fi router + two LED bulbs | 9.3–12 h | 9.3–12 h |
| CPAP, no humidifier, on the DC cable | 2.6–3.2 days | 2.6–3.2 days |
| Laptop (USB-C) + Starlink Mini | 7.8–9.7 h | 7.8–9.7 h |
Estimates from our published formula. Neither maker publishes standby draw, so both use the same default. Try your own devices in the runtime calculator.
How fast does solar refill each one from empty?
| Rated panels | C1000 Gen 2 (max 600 W) | Elite 100 V2 (max 1000 W) |
|---|---|---|
| 400 W | 3.7 sun-hours (1.2 winter days) | 3.7 sun-hours (1.2 winter days) |
| 800 W | 1.8 sun-hours (0.6 winter days) | 1.8 sun-hours (0.6 winter days) |
| 1,200 W | 1.7 sun-hours (0.6 winter days) | 1.2 sun-hours (0.4 winter days) |
| 1,600 W | 1.7 sun-hours (0.6 winter days) | 1.0 sun-hours (0.3 winter days) |
Panels deliver about 70% of their rating in real use, capped at each unit's solar limit. Winter days assume 3 peak sun hours, a national winter default from NREL data; your location may be higher or lower. Keep a panel string's open-circuit voltage at or below about 85% of the 60 V input limit, since it rises in the cold. More in our solar panel sizing guide.
When does the quiz engine prefer each one?
We ran five situations through the engine the quiz uses. The C1000 Gen 2 comes out ahead in 5 of 5. The gap narrows when you recharge from solar, where the Bluetti's 1,000 W input counts, but the Anker's published full-charge time, stated warranty, extra outlet and confirmed surge keep it in front. The Bluetti's extra 0.4 lb also puts it just over our 25 lb one-hand limit.
| Situation | Engine prefers | Why |
|---|---|---|
| Outage night: fridge, Wi-Fi, phones | C1000 Gen 2 | Scores 86 vs 70 (Anker vs Bluetti) |
| Same devices, recharged only from solar | C1000 Gen 2 | Scores 86 vs 79 (Anker vs Bluetti) |
| Off-grid weekend on solar: 12 V fridge, phones | C1000 Gen 2 | Scores 81 vs 73 (Anker vs Bluetti) |
| Camping, carried in one hand | C1000 Gen 2 | Elite 100 V2: 25 lb is heavier than you want to carry. |
| Remote work: laptop + Starlink Mini | C1000 Gen 2 | Scores 93 vs 76 (Anker vs Bluetti) |
Who should buy which
- Buy the Anker SOLIX C1000 Gen 2 if it's mainly for outages charged from the wall, you want to run a microwave or coffee maker, or you'll carry it to a campsite.
- Buy the Bluetti Elite 100 V2 if you're building a solar setup for a cabin, van or long outages and already have, or plan to buy, more than about 860 W of panels.
- Buy neither if you need a fridge, Wi-Fi and phones for a full day without recharging: a top-freezer fridge alone runs about 15 h on 1 kWh. The sizing quiz checks your exact devices, and our C1000 Gen 2 vs DELTA 3 Plus guide covers an expandable alternative.

What people actually ask
Which lasts longer, the Anker C1000 Gen 2 or the Bluetti Elite 100 V2?
Neither, on the same devices. Both are sold as 1,024 Wh LiFePO4 units, so runtime is effectively the same. Neither publishes its standby draw, so our estimates use the same default for both.
Which charges faster from solar?
The Bluetti. It accepts up to 1,000 W at 12–60 V and 20 A; the Anker takes up to 600 W at 11–60 V. The difference only shows once your panels deliver more than 600 W, which takes more than about 860 W of rated panels.
Which charges faster from the wall?
Anker lists a full charge in 49 minutes, but only with UltraFast mode switched on in its app and the cells above 20 °C; normal AC charging is 1,200 W. Bluetti lists 0–80% in 45 minutes at 1,200 W.
Can either one add an extra battery?
No. The C1000 Gen 2 has no expansion port, and Bluetti documents no native expansion for the Elite 100 V2. If you want room to grow, look at the EcoFlow DELTA 3 Plus or a 2 kWh unit such as the Anker C2000 Gen 2.
Which one is better for a CPAP?
Either works: both list a 10 ms UPS switchover and have a car outlet for a CPAP's DC cable, and both run a CPAP without the humidifier for several nights. Before you rely on one overnight, turn off any ECO or auto-off setting in its app, which can switch outputs off at low loads.
The bottom line
Same battery, same runtime, same 10 ms switchover, no expansion on either. The Anker SOLIX C1000 Gen 2 is the better pick for most people: more output, more USB-C power, a published fast charge and a 5-year warranty. The Bluetti Elite 100 V2 earns its place when solar is your main power source. Read more in our C1000 Gen 2 guide and Elite 100 V2 guide, or compare every model in the comparison chart.
