Baseus Comet Series Dual-Cable Digital Display Power Bank 20000mAh 22.5W

Baseus Comet Series Dual-Cable Digital Display Power Bank 20000mAh 22.5W

Two cables built into the body, five fast-charge protocols and a published rated capacity — the most completely specified 20000mAh bank we stock. Compare it across our power banks.

Two cables, not one

Banks with a built-in cable are common; two is not. One is Lightning for Apple devices at 20W PD, the other Type-C at 22.5W with SCP for Huawei and most Android phones. Between them you can charge almost anything without carrying a lead, and you can charge two devices on the built-in cables at once. The trade-off is the same as with any attached cable: a worn one limits the whole unit rather than costing little to replace. Having two does at least halve the odds of being stranded by one failing.

It publishes the number most brands hide

Baseus states a rated capacity of 12000mAh at 5V/2.4A from the 20000mAh cell, and an energy conversion rate of at least 75 per cent. That is genuinely useful. Almost every brand quotes only the cell capacity, which overstates what your phone receives by around a third. Twelve thousand delivered is what you should plan around — roughly three full phone charges. Being told this up front is worth more than a slightly higher headline figure.

Five protocols and two-way charging

PD, QC, AFC, FCP and SCP are all supported, which covers Apple, Qualcomm-based Android, Samsung and Huawei fast charging between them. The Type-C port also works as an input at up to 12V/1.5A, so the bank itself recharges quickly. A low-current mode handles earbuds and watches, which some banks refuse to charge at all because the draw is too small to register.

Warranty and travel

At 77Wh it flies without airline approval, cabin baggage only. Note that the warranty term here is shorter than on the Awei banks in this range — both are stated in the specification tables. Our warranty policy explains how a claim works.
