Anker SOLIX C800 Portable Power Station

The most consistent note from testers is the fan. Backup Power Hub measured it at 35 dB at idle (under 400W), 42 dB at medium load (400–800W), and 47 dB under heavy load (800–1,200W) — audible under sustained high draw, not harsh. Reviewers of the camping-light sibling noted it gets more present above roughly 950W of fast charging in a warm room; it's the same charging engine, so expect some fan when you push it.

The gotcha worth setting up before your first outage: the power-saving logic can drop low-draw devices. Anker's own support docs note the AC outlets switch off after about 15 minutes with no plug detected, a 12-hour standby power-off when no load is sensed, and USB ports that can cut out on a very small draw — reactivated by unplugging and replugging. You set the standby behavior in the app. None of this is a defect, but a trickle load like a phone on USB can quietly stop charging if you haven't adjusted it. Set it up at home, not on your first night.

Two more limits owners should plan around: Backup Power Hub notes the unit won't accept a charge below 32°F (a normal LFP protection against lithium plating), so a freezing garage or winter vehicle is a poor place to top it off; and there's no IP weather rating — the protective bag is sold separately, so keep it dry. Genuine multi-year failure reports are still sparse as of mid-2026 — it's a relatively new unit — so we can't point to a durable problem pattern, and we won't pretend the absence proves anything either way.
