The catch
Anker SOLIX C800
768Wh capacity can’t be changed.
Side by side
Anker SOLIX C800 vs BLUETTI AC70: Anker leans to AC output and BLUETTI to charging options, on the same 768 Wh
Quick verdict
If your steady AC load needs more than 1000W but stays within 1200W, the C800 is the one. The AC70 is for equipment that fits within 1000W, where a larger solar setup or two 100W USB-C ports will come in handy. Each stores 768Wh and weighs about 23 lb, so the choice is mostly about output versus charging connections.
Before you buy
Why, and what it costs you
AC output goes up 20%, with no more battery
Both hold 768Wh, and C800 provides 1200W continuous AC output against AC70’s 1000W.
Where this comes from
(1200 − 1000) ÷ 1000 × 100 = 20%. Extra available watts don’t add runtime to a fixed battery.
The catch
BLUETTI AC70
Despite the same nominal battery capacity, the 22.5-pound body is heavier than the RIVER 2 Pro.

Anker SOLIX C800
- Why pick it
- A steady load of up to 1200W calls for more AC headroom.
- Camping lights are already in your gear, so the C800 Plus removable lamps aren’t needed.
- The catch
- 768Wh capacity can’t be changed.
BLUETTI AC70
- Why pick it
- Making use of more than 300W of compatible solar input appeals to you.
- Each of two USB-C devices should get up to 100W of port headroom.
- The catch
- Despite the same nominal battery capacity, the 22.5-pound body is heavier than the RIVER 2 Pro.

What this page compares
Anker C800 and BLUETTI AC70 compared on steady appliance power, solar input and two-laptop charging, with the same 768Wh battery capacity.
Battery and carrying weight are close, yet the AC advantage and the solar advantage point different ways.

In practice
Differences you will notice
AC output goes up 20%, with no more battery
Both hold 768Wh, and C800 provides 1200W continuous AC output against AC70’s 1000W.
How we worked this out
(1200 − 1000) ÷ 1000 × 100 = 20%. Extra available watts don’t add runtime to a fixed battery.
Maximum solar acceptance is two thirds higher on AC70
Against the C800’s 300W ceiling, its 500W solar ceiling is about 66.7% higher.
How we worked this out
(500 − 300) ÷ 300 × 100 = 66.7%. What comes in depends on panel voltage, current, weather and charge state.
C800’s second USB-C port can’t handle the second 65W laptop
A 65W request is 35W over that 30W port and under either AC70 100W port.
How we worked this out
65 − 30 = 35W. C800 may still charge at a lower negotiated power, but the port can’t deliver a full 65W.
Option A

Anker, A1753
SOLIX C800
This camping station has AC headroom for more than lights and laptops. The battery and inverter are the same as in the C800 Plus, minus the removable camping lamps.
- Best for
- Campers with lighting of their own who want a capable mid-size AC station.
Facts we checked
- 1200W combined AC output from a 768Wh battery.
- About 23.1 lb.
- Solar input of 300W, from 11V to 60V and 10A maximum.
- A 100W USB-C output and a 30W USB-C output.
- Up to 1100W UltraFast AC charging and 20ms transfer.
Option B
BLUETTI, AC70
AC70
This 768Wh station has inverter headroom for medium-size camp appliances, plus two 100W USB-C ports. A 500W solar input is strong for a battery this size.
- Best for
- Camping with solar recharging as a real plan
Facts we checked
- 1,000W rated AC output from a 768Wh LFP battery
- Two 100W USB-C ports and regulated 12V/10A DC, at about 22.5 lb

Spec by spec
Where they really differ
| Spec | Anker SOLIX C800 | BLUETTI AC70 | In practice |
|---|---|---|---|
| Battery capacity | 768Wh | 768Wh | The nominal energy budget at the start is the same for both. |
| Continuous AC output | 1200W | 1000W | C800 handles an additional 200W of simultaneous steady demand. |
| Maximum solar input | 300W | 500W | From a suitably matched array, AC70 can take more. |
| USB-C outputs | One 100W and one 30W | Two 100W | Two demanding USB-C devices get more flexibility from AC70. |
| Listed weight | 23.1 lb | 22.5 lb | Carrying weight differs by only about 0.6 lb. |
| Published transfer time | 20ms | 20ms | These two aren’t told apart by the transfer headline. |
Trade-offs
What each pick costs you
With Anker SOLIX C800
- Solar charging tops out at 300W.
With BLUETTI AC70
- Only suitable resistive loads should use Power Lifting. Base everyday plans on the 1,000W rated inverter and set the lifting-mode headline aside.
Decision guide
How to decide
The C800 handles the bigger steady appliance, and the AC70 handles the larger solar or USB-C setup.
A bigger appliance points to the C800
With a 1200W continuous rating, the C800 has room for a steady total beyond the AC70’s 1000W rating. For specific cooking or work equipment, even on a short run, that difference is useful. Go by the actual input power and not a product’s cooking-output number. Starting surges and individual outlet limits still need separate checks.
The AC70’s solar input helps on a longer stay
Each battery holds 768Wh, so you carry the same amount from home. The AC70 accepts up to 500W of solar, against 300W for the C800. That matters once your array can exceed 300W and daylight charging counts. With only one modest folding panel on the trip, it brings little advantage.
Charging two laptops shows the port difference
The C800 has a 100W USB-C port and a second, 30W port, whereas the AC70 has two 100W ports. For a pair of laptops that each need around 65W, the AC70 offers the more suitable direct connections. The C800 can still run an AC laptop charger, but that adds a power brick and draws on the inverter instead of a second high-power USB port.
What this page can’t tell you
- Equal nominal capacity gives no basis to infer a runtime difference.
- How fast USB charges depends on the device, the cable and the negotiated power profile.
