Summary

A 20,800mAh laptop-class power bank with up to 100W from a single USB-C port and 145W shared across two, four ports in all and a smart display. The catch is that no independent lab has tested it and the retailer spec sheets disagree on secondary-port output, so treat the performance numbers as manufacturer claims.

Strengths

  • Laptop-class output: 100W from a single USB-C port, 145W shared across two.
  • Four ports (2x USB-C, 2x USB-A) run several devices at once.
  • A smart display shows live wattage and time estimates.
  • At 77Wh it stays under airline carry-on limits.
  • Recharges at up to 65W, roughly 1.5 to 2 hours.

Weaknesses

  • No independent lab has measured it, so every performance figure is a manufacturer claim.
  • Retailer spec sheets conflict on weight, USB-A output and the second USB-C port.
  • Brand-level reports mention a swollen battery and a unit that stopped holding charge.
  • The unit is not user-serviceable, and the US warranty term could not be verified.

Ports and charging

The 145W figure is a two-port combined number, not per port. Baseus says the split across the two USB-C ports is automatic, but buyer sheets disagree about the secondary ports: USB-A is either 33W or 18W per port, and the second USB-C port is either 45W or up to 100W. Don’t assume two symmetric 100W ports. Charging is capped at 65W input, and the unit deliberately trickles above 80% to protect the cells.

No independent test

No established outlet has instrumented this exact model. Coverage is the manufacturer’s own pages, launch and deal articles that restate the spec sheet, and retailer listings. ChargerLAB’s teardown of a Baseus 145W unit is a different power bank, the 25,000mAh E0028H. Treat the output and efficiency claims as unverified.

Owner reports and warranty

Exact-model owner evidence is thin. Brand-level signals on Trustpilot (the Baseus store, not this model) include a swollen battery that Baseus refunded and a unit that stopped holding charge after four months with difficult warranty handling. Those are anecdotes, not a failure rate. The unit is not user-serviceable, the US warranty term could not be confirmed, and EU/UK pages point to a 14-day return window with a 2-year manufacturer warranty.

Is it worth it?

The value case is price-led. Baseus lists it at $89.99 on its US store, launch coverage put it at $99.99, and 2025 deal posts tracked it as low as $44.99. Above about $90 with no discount the case weakens: the spec sheet is common across 145W Baseus models, no independent test validates real-world output, and brand-level owner feedback includes battery-durability cautions. There are no recurring costs beyond the purchase and the included cable; a 65W+ USB-C wall charger is needed to use the full recharge speed and is not included.
