The honest backbone

The Decision Receipt

Why it's here
Best-value compact: 288Wh and a genuine 300W AC output in a grab-and-go size, with fast 140W two-way USB-C and 8 ports. Undercuts Jackery's 300 on price with strong reviews.
Who should buy it
Commuters, students, and day-trippers who want light, affordable backup for phones, laptops, and a CPAP.
Who should skip it
Skip it if you need to run a mini-fridge or CPAP through a full night or power larger AC gear — 288Wh / 300W is a grab-and-go top-up unit, not an overnight or whole-outage backup.
The main tradeoff
You trade real capacity and inverter power for a genuinely compact, low-cost, grab-and-go size with strong port selection.
What could change this
Buy the AC model (not the USB-only DC version) and confirm whether the wall charger is included; if you need overnight runtime, step up to the RIVER 2 Pro.

What owners actually report

Aggregated from real verified-buyer reviews and long-term owner reports — not our own hands-on test. Basis: ~4.6 stars from ~1,750+ Amazon verified buyers, plus independent reviews (Trusted Reviews, Battery Skills) and Anker community troubleshooting threads.

288Wh LiFePO4

~50 min at 140W
Recharge to 80%
~4-5 hours runtime
Travel CPAP (30-60W)
~4.8 full charges
60Wh laptop charges
What breaks, and when
  • Fan cycling and heat under load. Despite the marketed 25dB whisper-quiet rating, owners report the fan kicking in audibly during 140W fast-charge and heavy AC load, with the unit running hot near full charge because charging does not taper.
  • App/Bluetooth connectivity drops. Owners frequently report trouble pairing or staying connected to the Anker app, needing restart, Bluetooth toggle, or re-pairing.
  • Auto-shutoff and isolated charge faults. The power-saving mode switches off with low-draw devices unless low-current mode is enabled, and at least one owner reports a unit that will not accept charge past 25%.
Longevity

Claimed 3,000 cycles to 80% (~10 yr); one reviewer saw no capacity drop after rigorous cycling, but there is no multi-year owner data to confirm it yet.

What owners praise
Strong value with genuine LiFePO4 longevity and fast 140W rechargeCompact and travel-friendly (~15% smaller than similar-capacity rivals)
