Portable power for multi-device users

The ALOGIC Roam power bank stores 21000 mAh and delivers up to 100 W through its primary USB-C port. A second USB-C port supplies 18 W while Qi2 wireless charging reaches 15 W and standard Qi provides 5 W. An integrated Apple Watch charger and MagSafe-compatible surface round out the feature set for travellers carrying a phone, watch and laptop.

Build integration and cable reduction

The fold-up design includes a snap-on phone stand so the unit doubles as a desktop dock. One 100 W USB-C cable can recharge the bank at full speed and then power a laptop, removing the need for a separate laptop charger. Wireless pads eliminate watch and phone cables, and the 21000 mAh capacity is permitted on commercial flights.

Sustained-load behaviour

Under continuous 100 W output the bank maintains 20 V at 5 A until the stored energy depletes. The 18 W port and both wireless surfaces operate simultaneously without reducing the primary port’s voltage. Heat is managed passively through the folded aluminium shell so output remains stable during extended charging sessions.

Questions about this item

What is the maximum sustained output the 100 W USB-C port can deliver before it throttles?

The USB-C port supports 5 V, 9 V, 12 V, 15 V and 20 V at up to 5 A, giving a peak of 100 W; sustained output will depend on the connected device's power profile and the bank's internal thermal limits.

How hot or loud does the power bank get when charging a laptop at 100 W for several hours?

The unit has no fan; it relies on passive cooling, so it will become warm to the touch during prolonged 100 W loads but remains silent.

Which cable must I already own to reach the 100 W rating from the USB-C port?

A USB-C to USB-C cable rated for 5 A / 20 V (100 W) Power Delivery is required; lower-rated cables will limit the output.
