Verify that your devices accept USB-C Power Delivery up to 45W for the fastest rates. The power bank itself recharges at 30W PD input and reaches full capacity in about three hours. It measures 4.98 in x 2.93 in x 1.26 in and weighs .79 lb, so confirm it fits your bag or pocket. No other cables are included in the box.

Suits travellers wanting one-cable convenience

Ideal for users who want a single compact unit with a built-in cable for daily commutes, camping or hurricane preparedness. Not suited for buyers who need multiple simultaneous ports, wireless charging, or higher output for power-hungry laptops. Also not for those who prefer a separate, replaceable cable.

Questions about this item

Does the M32 come with its own USB-C cable or do I need to buy one separately?

A USB-C cable is built into the M32 and retracts for storage, so no separate cable is required for USB-C devices.

Should I choose the 20000 mAh version or a smaller capacity for a weekend trip?

The 20000 mAh capacity provides multiple full phone charges and can top up a lightweight laptop, making it suitable for several days away from a socket.

What does the 45 W rating mean when I plug in my laptop?

The power bank can deliver up to 45 W over USB-C, enough to fast-charge compatible smartphones, tablets and lightweight laptops at their maximum supported speed.
