At 48,000mAh (153.6Wh) with up to 300W total output, this is less a phone charger than a portable power source for a whole crew — laptops, tablets, phones and camera accessories running at once off five ports (three USB-C, two USB-A).
The 140W PD3.1 port charges a laptop at full speed and also recharges the bank itself in about 1.5 hours, so it can be turned around between shoot days. It uses LiFePO₄ cells, which is the chemistry chosen for cycle life and thermal safety rather than for the smallest possible package. A digital display shows remaining charge, and there is an LED flashlight with high, low and SOS modes.
Rented for location shoots without reliable mains, long outdoor days and events where several devices need topping up between setups. Note its capacity is above the usual airline carry-on limit, so plan around that if the job involves a flight.
