  • Power Delivery up to 45 W recharges the bank in 3 hours
  • USB-C, USB QC3, USB-A and Lightning ports cover multiple devices

High-capacity portable power

The Tzumi 30,000 mAh power bank delivers up to 45 watts of Power Delivery 2.0 through its USB-C port, alongside a USB QC3 port, a standard USB port and a Lightning input and output. It is built for users who need to keep smartphones, tablets and USB-C laptops running away from mains power.

Build and daily connections

A black plastic shell houses the 30,000 mAh cell and internal circuitry that protects against overheating and over-charging. The included USB-C cable and the dedicated Lightning port mean the bank itself can be recharged in about 3 hours with a 45-watt adapter, far quicker than the 24 hours typical of similar-capacity units.

Deciding specification

The single figure that determines suitability is the 30,000 mAh rating, which the supplier equates to roughly 10 smartphone charges, 2.5 tablet charges or two full cycles for a USB-C laptop. Buyers who need more stored energy than this should look elsewhere.

Questions about this item

How fast does Power Delivery 2.0 recharge the 30,000 mAh bank at 45 Watts?

With a 45-Watt adapter and the included Type-C cable, the bank reaches full charge in about 3 hours instead of the 24 hours typical for similar capacities.

What ports and cables are required to connect and mount the unit?

It provides one high-speed USB, one USB QC3, one Type-C port and a Lightning input; the Type-C cable is included, so only a 45-Watt USB-C charger is needed to achieve the 3-hour recharge.

How do you enable the fastest recharge and what step is often missed?

Use the included Type-C cable with a 45-Watt Power Delivery 2.0 wall charger; the common mistake is plugging into a lower-wattage adapter, which falls back to the 24-hour charge time.
