Bambu Lab BML-28793 batería externa 20000mAh 74Wh con carga rápida de 22,5W, 3 salidas, indicador LED, negro

For anyone tired of juggling multiple chargers, the Bambu Lab BML-28793 packs a serious 20000mAh punch into a rugged aluminium-and-ABS shell. Unlike slim fashion power banks that sacrifice capacity for looks, this unit balances a 74Wh lithium-polymer core with three simultaneous outputs and 22.5W fast charging, so you can top up a phone, tablet and earbuds at the same time without hunting for a wall socket.

Highlights

• 20000mAh / 74Wh lithium-polymer battery — enough for multiple full phone charges
• Three output ports: 2× USB-A + 1× USB-C, with up to 22.5W single-port output
• Dual input: Micro-USB and USB-C, both supporting 18W fast recharge
• Digital LED display shows exact remaining charge in percent
• Supports Power Delivery, Quick Charge, Huawei SuperCharge and AFC protocols
• Seven safety protections: overcharge, over-discharge, overcurrent, overpower, overvoltage, short circuit, overheating
• Durable aluminium alloy + ABS body in black

In daily use

The BML-28793 recharges in roughly 6–7 hours with an 18W adapter, and the LED readout removes all guesswork. USB-C output delivers up to 20W for modern phones, while the first USB-A port can push 22.5W to compatible devices. The second USB-A is ideal for accessories or older gadgets. Total output is capped at 5V/3A across all ports, so heavy multi-device charging will share power intelligently.
