Capacity and purpose

The DIAMUAR P58DL is a 30000mAh lithium-polymer power bank that delivers up to 30W Power Delivery fast charging. It suits travellers and commuters who need multiple phone recharges and a built-in 3W LED flashlight for low-light situations.

Who it suits and who it does not

The unit provides roughly five full cycles for an iPhone 12, 4.5 cycles for an iPhone 13 and four full charges for a Galaxy S22, making it practical for users carrying a phone and a tablet. Buyers who need more storage capacity than 30000mAh or who require laptop-class output above 30W should look at something else.

Setup checks before ordering

Confirm that your devices accept USB Type-A or USB Type-C input at 5V/3A or 9V/2A so they can use the 30W PD and 22.5W SCP profiles. The power bank itself recharges through its USB-C port at up to 30W, so ensure you have a compatible charger and cable to reach the six-hour refill time. The 5.74 in x 2.87 in x 1.25 in dimensions should fit your bag or pocket.

Questions about this item

Which cables or adapters do I need to charge an iPhone 15 from the USB-C port?

Use a USB-C to Lightning cable or a USB-C to USB-C cable with a Lightning adapter; the power bank’s USB-C output supports PD 30W for fast charging.

Will the USB-A ports still fast-charge a Galaxy S22 that only supports older Quick Charge versions?

Yes, each USB-A port delivers up to 22.5W via SCP and 9V/2A, which is compatible with Quick Charge 4.0 and earlier versions used by the S22.

How can I confirm the power bank is recharging itself at the full 30W rate?

The LED display shows the input voltage and current in real time; when it reads 9V/2A or 5V/3A during recharge, the unit is drawing its maximum 30W.
