Baseus Airpow 20W 10000mAh Power Bank

The Baseus Airpow 20W 10000mAh Power Bank is sized for a pocket or a small bag rather than a backpack — 10,000mAh is enough to take most phones from empty to full roughly twice, which covers a full day out without needing the bulk of a 20,000mAh brick. The 20W output supports fast charging on compatible phones, so a top-up between meetings or on a commute is noticeably quicker than a basic 5W bank.

Baseus builds in multi-layer protection circuitry against overcharge, overheat, and short circuits, which matters more on a battery you're carrying in a pocket than most buyers realise. The trade-off of the compact 10,000mAh size is capacity: it will not fully recharge a large-battery flagship phone twice over, and it will only trickle-charge a tablet rather than power it quickly.

• 10,000mAh capacity in a pocketable form factor
