Anker SOLIX C800 Review: Big Power, Small Footprint
✅ What We Like
- Incredibly fast 1-hour charging
- LiFePO4 battery with 5-year warranty
- Compact and well-designed
- 1200W handles most small appliances
❌ What Could Be Better
- Not expandable like bigger Anker units
- Solar input limited to 500W
- USB-C could be higher wattage
The sun had already dropped behind the ridge when Marcus realized his mistake. Three days into a remote camping trip near Bishop, California, and his camera batteries were dead. All of them. The time-lapse he’d planned for the Milky Way rising over the Sierra? Wasn’t happening.
He pulled out his phone. Four percent battery.
“I should’ve charged everything at the trailhead,” he muttered to nobody, because there was nobody for miles.
That’s when he remembered the Anker SOLIX C800 sitting in his truck bed, still boxed from the REI run two days earlier. He’d bought it on impulse — a “maybe I’ll need this someday” purchase. Someday had arrived.
Twenty minutes later, he had the C800 set up on a picnic table, camera batteries plugged into the USB-C ports, and his phone charging off one of the AC outlets. The unit’s display glowed softly: 94% remaining. More than enough for tonight’s shoot and tomorrow’s drone footage.
By midnight, Marcus had captured the best astrophotography of his life. The C800 hummed quietly, powering his laptop for editing and a small LED panel for workspace lighting. When he finally crawled into his tent at 2 AM, the power station still showed 61%.
That’s the thing about the C800 — it’s not trying to be everything. It’s trying to be exactly what most people actually need, packaged in something you can carry with one hand.

What We Liked
The charging speed is absurd. Plug it into a wall outlet, go make coffee, and by the time you’ve finished your first cup, you’re at 60%. An hour later, it’s full. This matters more than you’d think — no more planning your day around “I need to charge the power station.” You just plug it in when you think about it, and it’s ready when you need it.
The build quality feels premium. This is Anker, so that’s expected, but the C800’s handle feels solid, the ports are well-placed, and the display is bright without being distracting. The whole unit has that “I’m going to survive being tossed in a truck bed” vibe.
Four AC outlets at this price point. Most 768Wh units give you two. Having four means you’re not playing the “which device gets priority” game. Phone, laptop, camera charger, and a fan can all run simultaneously.
LiFePO4 with a 5-year warranty. Anker’s betting this thing lasts, and they’re putting their money where their mouth is. After 3,000 cycles, you’ll still have 80% capacity. Charge it once a week for fifteen years, and it’ll still work.
What Could Be Better
No expandability. The C800 is what it is. If you outgrow 768Wh, you’re buying a whole new unit, not adding a battery. That’s fine for most users, but it’s worth knowing upfront.
USB-C power delivery is limited. The USB-C ports work fine for phones and tablets, but if you’re hoping to fast-charge a MacBook Pro at full speed, you’ll want to use the AC outlet with your laptop’s charger instead.
500W solar cap. In ideal conditions, you could theoretically push more power into this thing. Anker’s limited it to 500W, which keeps costs down but means solar charging takes 2-3 hours instead of potentially faster.
Runtime Estimates
Here’s what you can realistically expect from the C800:
| Device | Runtime |
|---|---|
| Smartphone (15W) | ~43 hours |
| Laptop (50W) | ~13 hours |
| CPAP without humidifier (40W) | ~16 hours |
| 32” LED TV (50W) | ~13 hours |
| Mini fridge (75W average) | ~8.5 hours |
| Coffee maker (1000W) | ~39 minutes |
| Electric blanket (100W) | ~6.5 hours |
Who Should Buy This
Content creators and photographers. If your gig involves cameras, drones, laptops, and being places without outlets, the C800 hits the sweet spot between “enough power to matter” and “light enough to actually bring.”
Car campers who want real power. Not just phone charging — actual appliances. Fans, lights, coffee makers, maybe a small TV for the kids. The C800 handles all of it without breaking a sweat.
Emergency backup for apartments. If you don’t have space for a giant power station but want something that’ll keep your phones charged, run a modem and laptop, and maybe power a small space heater for an hour, this is your unit.
The Verdict
The Anker SOLIX C800 is the power station equivalent of a really good cooler — not the biggest on the market, but thoughtfully designed, built to last, and perfect for 90% of the people who’ll use it. At $399, it’s priced fairly for what you get, and the 5-year warranty means Anker expects it to stick around.
If you need more capacity or expandability, look elsewhere. But if you want something you can grab with one hand, toss in the car, and forget about until you need it, the C800 delivers exactly that.
Rating: 4.5/5 — Excellent for its intended purpose, with minor limitations that won’t matter to most users.
