Brand: Samsung

Two worlds coexist at Samsung: replacement batteries for Galaxy phones, and the Samsung SDI cells found inside a good share of portable power gear.

Phone batteries are chosen on the exact part number printed on the cell, not on the phone's marketing name: a single generation can carry several part numbers depending on the region. On the cell side, Samsung SDI 21700s are a market reference for torches, vaping devices and custom packs, with a high continuous discharge current. We systematically check the claimed real capacity, often overstated on the copies sold through marketplaces.

Samsung 10,000 mAh (wireless)

See price and availability (8)

Charge wirelessly or over 25 W USB-C, up to three devices at once, with the compact and elegant Samsung 10,000 mAh wireless battery pack.

Capacity: 10,000 mAh
Wireless charging: Qi induction, 7.5 W
Wired output: 2 USB-C, 25 W max
Weight: 222 g
Qi wireless + 2 USB-C 25 W, up to 3 devices at once

The Samsung 10,000 mAh wireless battery pack (reference EB-U2510) combines two charging modes: a Qi induction surface (7.5 W) to rest a phone, a watch or earbuds directly on it, and two wired USB-C ports up to 25 W. It can power three devices at once, two wired and one wireless. Compact (222 g), finished in an elegant beige and partly made from recycled plastics, it is ideal for fast charging day to day and on the move, USB-C cable included.

In-depth reviewRead our full review → 3.7/5 We took to this Samsung induction battery for its two-in-one nature. Day to day, simply dropping the phone on top to charge it, with no cable to find, is genuinely pleasant, just like charging a Galaxy Watch or earbuds the same way. And when you want speed, the 25 W USB-C ports do the job: you get a good chunk of a phone's battery back in little time. Being able to power three devices at once (two cables plus induction) is a real help when travelling, when everyone needs juice. The LED indicators are clear, you always know how much is left, and the included cable saves carrying one. The beige finish is pretty and a change from the usual black shells. Two honest reservations: induction charging is handy but slow (7.5 W), so for speed you are better off using USB-C, and at 222 g it makes itself felt in a small pocket. But for mixed wireless and wired use, with this capacity and versatility, it is a genuinely well-designed power bank.
