Baseus Adaman Metal 22.5W 20000mAh Power Bank

The display is what sets the Adaman apart from most packs at this capacity. Instead of four indicator dots it shows the remaining percentage alongside live voltage and current — so you can see what your phone is actually drawing, not just guess whether fast charging kicked in. Compare it across our power banks.

Capacity and what you really get

20000mAh at 3.7V is 74Wh of stored energy, with a rated output capacity of 12000mAh. That second figure is the honest one: converting cell voltage up to what your phone needs loses energy as heat, so no power bank delivers its nominal number. Baseus quotes a conversion rate of 75% or better, which is respectable for this class.

Output

22.5W maximum, with Power Delivery and Quick Charge support plus Huawei's SCP protocol at 5.5V/3A. The USB-C port runs 5V/3A, 5.5V/3A on SCP and 9V/2A. That covers fast charging on the phones actually sold here rather than only the PD standard.

Build and display

A metal body rather than plastic, which conducts heat away from the cells better and survives a bag. The LED readout gives percentage, voltage and current at a glance — genuinely useful for diagnosing why a device is charging slowly, which is usually the cable rather than the pack.

Questions and answers
Why is the rated capacity lower than 20000mAh?

Because converting the cell's 3.7V up to the 5V your phone needs loses energy as heat. 12000mAh is what actually reaches your devices. Every power bank works this way — most simply do not print the second number.

What does the display show?

Remaining percentage, plus live voltage and current. That last pair is genuinely useful: it tells you whether fast charging engaged or whether your cable is limiting things, which indicator dots cannot.

Will it fast-charge a Huawei phone?

Yes. It supports SCP at 5.5V/3A alongside Power Delivery and Quick Charge, so Huawei and Honor devices get their own fast-charge protocol rather than falling back to a slow default.

How many phone charges will I get?

Roughly three full charges for a typical phone with a 4000 to 5000mAh battery, based on the 12000mAh rated output rather than the headline capacity.

Can I take it on a plane?

74Wh is under the 100Wh limit airlines generally allow in cabin baggage. Power banks must travel in carry-on, never checked. Confirm your airline's rules before you fly.
