The Decision Receipt
- Why it's here
- Flagship large power bank: 27,650mAh and 250W tops off a laptop, phone, and tablet at once, then refills itself in ~37 minutes. Still carry-on legal at 99.54Wh.
- Who should buy it
- Laptop-toting travelers and remote workers who charge multiple devices between outlets on the road.
- Who should skip it
- Skip it if you need to power a 110V wall device — this is a USB-only bank with no AC outlet; for a real socket you need a power station or an inverter.
- The main tradeoff
- You give up AC output and station-class capacity in exchange for a pocketable, airline-carry-on-legal (99.54Wh) bank that still pushes 250W across ports.
- What could change this
- The full 250W needs multiple ports in use (a single port caps around 140W) and the charging dock is sold separately — factor both in; if you only ever charge a phone, a cheaper, smaller bank is enough.

What owners actually report
Aggregated from real verified-buyer reviews and long-term owner reports — not our own hands-on test. Basis: Multiple independent bench tests (Android Central, Macworld, Gadgetoid, Consumer Reports) plus Best Buy and Amazon verified-buyer reviews.
- Heat during high-power charging. The pack becomes very warm-to-hot at 200W+ input or output, though the onboard gauge reports it stays within safe limits.
- Heavy and bulky. At ~1.45 lb it is far too large and heavy for a pocket, a common owner complaint for an everyday carry charger.
- Usable capacity below rated and fast drain. Real delivered energy is roughly 85% of the rated ~99.5Wh after conversion loss, and it empties in under ~20 minutes when pushed near its 250W ceiling.
Li-polymer cells rated ~500 cycles to 80% (well short of LiFePO4 stations); one tracked review saw ~5% capacity loss after 3.5 months, plus typical ~2-3%/month self-discharge when idle.
