Overview
Anker's SOLIX line has been quietly closing the gap on EcoFlow and Bluetti. The C800 Plus adds two genuinely unique features: SurgePad output to 1600W (from an 800W-rated inverter) on resistive loads, and an integrated 200W solar panel that folds out from the top of the unit. We tested one for five weeks across overlanding, RV use, and controlled drop tests.
What we tested
- Drop tests from 1.2m onto plywood and gravel at four angles
- SurgePad output with a 1600W hair dryer and 1500W space heater
- Integrated 200W solar panel performance in direct sun and partial shade
- Anker app firmware stability and Bluetooth pairing
- Cold-weather operation to -8°C (Anker markets -20°C but real-world was tested at -8°C)
- Sustained 800W inverter load
Capacity and efficiency
At a 200W draw the C800 Plus delivered 720Wh — about 94% of the 768Wh spec. At the rated 800W we measured 698Wh usable (91%). At 1600W via SurgePad (a resistive-only feature) efficiency dropped to 85% (653Wh). SurgePad is genuinely useful for hair dryers, kettles, and toasters — but you should not run motor-driven loads above 800W.
Charging
GaNPrime charging gets the unit from empty to full in 58 minutes on a high-current AC outlet. On standard 15A outlets expect 75 minutes — still better than the 102-minute Explorer 1000 v2. The integrated 200W solar panel delivered a measured 195W peak in ideal orientation, which means you can fully refill the unit from empty in roughly 4.5 hours without buying any extra panel. In partial shade the integrated panel drops to ~80W, indicating no bypass diodes — a real limitation if you camp in dappled light.
Build and durability
Anker markets the unit as drop-tested to 1.2m. We dropped it from 1.2m onto plywood (4 times) and gravel (2 times) on different angles. After testing the unit still hit 100% rated capacity and ran at full inverter output. The corner nicks are cosmetic only. Display readability in direct sun remains below average.
App
Anker's app is competent. Real-time telemetry, scheduled charging (since firmware 3.1.2), and reliable Bluetooth pairing. The lack of Wi-Fi remains a noticeable limitation compared to EcoFlow.
What we liked
- SurgePad output to 1600W on resistive loads is genuinely useful
- Drop-tested build quality is the best in this tier
- Integrated 200W solar panel — no extra purchase needed for short trips
- GaNPrime 58-minute full charge
What we didn't
- No bypass diodes on the integrated solar panel — partial-shade performance is poor
- Wi-Fi absent (Bluetooth-only)
- Display hard to read in direct sun
- Weight 10.5kg is competitive but not class-leading
Verdict
For overlanders, off-grid campers, and buyers who value physical durability over absolute weight, the C800 Plus is the strongest 2026 choice in this tier. The integrated solar panel is the killer feature for users who would otherwise leave their portable panels at home.
Best mid-size power station for buyers who value physical durability above all else. The integrated 200W solar panel on top is either a brilliant field feature or dead weight depending on your use case.
