A 10400 mAh battery in a plastic casing from the Air Gifts stone line, measuring 13 by 8.1 by 3.6 cm. Four diodes on the body report the remaining charge, so the state of the unit is visible before it goes into a bag. Input runs at 5V and 1-2A, output at 5V and 2.1A, and a USB-C cable is supplied with it.

Capacity in this range covers several phone refills between wall sockets, which is the usual reason a power bank stays in a rucksack instead of a drawer. The single output makes it a personal device rather than a shared one, and the grey finish sits quietly next to any phone or tablet. It is delivered in a paper box, ready to be passed on as it is.

Power banks earn their place in gift programmes where recipients spend the day away from a desk: trade fair visitors, field sales and service engineers, conference speakers, drivers, and students at a recruitment stand. They also work as a prize in a raffle or as a follow-up gift after a sales meeting, where something useful outlasts a printed brochure.

MerchRepublic can put your logo on the flat face of the casing, price the item in campaign volumes, and ship the finished order to companies across Europe. Send us the quantity and your artwork file and we will return a quotation for the branded run.
