What this power bank delivers

The DIAMUAR P056 is a 20000mAh lithium-polymer power bank rated at 45W output. It suits commuters, travellers and anyone needing emergency backup for phones, tablets and lightweight laptops. A built-in braided USB-C cable and a 3W flashlight add convenience for daily carry and outdoor use.

Check your devices before ordering

Confirm your hardware accepts USB-C Power Delivery up to 45W for fastest charging. The built-in cable is USB-C only, so devices with Lightning or Micro-USB ports will need their own adapter or cable. Total simultaneous draw across the two USB-C ports and one USB-A port is shared, so peak speed may drop when three devices are connected.

Replaces separate chargers and cables

This unit consolidates a high-capacity battery, a 45W USB-C charger and a durable cable into one pocket-sized block. It removes the need to pack a wall charger and loose cords for short trips. The jump is worth it if you regularly drain a phone and a laptop on the same day and want a single recharge that refills the bank in about three hours.

Questions about this item

Does the power bank include a charging cable or do I need to buy one separately?

The unit has a built-in braided USB-C cable tested to 30000 bends, so no extra cord is required for USB-C devices; other cable types are not included.

Which output port should I use to get the 45W fast charging speed?

Both USB-C ports deliver up to 45W each, while the USB-A port is limited to 22.5W; use either USB-C port for the highest charging rate.

How many full phone charges can I expect from the 20000mAh capacity?

The manufacturer estimates about 3.8 complete cycles for iPhone 17 Pro, 3 cycles for iPhone 16 Plus, and 2.8 full charges for Galaxy S25+.
