Built for the Galaxy S25.
Five portable chargers tested for fast charging, real capacity, and daily-carry comfort on the Samsung Galaxy S25.
Clutch Pro 5000mAh with USB-C tail.
Thinnest power bank on the market, built-in USB-C cable plugs straight into the S25 for reliable Power Delivery charging, and TSA-approved for travel. For S25 owners who want a charger that disappears into a pocket, this is it.
What we looked at
Real capacity on the S25
How many full top-ups you actually get on the S25's 4,000 mAh battery.
USB-C PD output
The S25 supports up to 45W Super Fast Charging 2.0. We measured actual wattage delivered.
Daily carry
Thickness, weight, and how it fits alongside a Samsung phone in pockets and bags.
Clutch Pro 5000mAh
Order it with the USB-C tail (this is the version for S25). The built-in cable plugs straight into the S25's USB-C port for 18W Power Delivery. ~6mm thick fits in places no other charger can: a slim card pocket, a clutch purse, or the elastic on a passport sleeve. The 5,000 mAh capacity gives you one full S25 charge with ~20% reserve.

If you're a Galaxy S25 power user — mobile hotspot, DeX mode, navigation — the Anker 737 is the most capable option. 24,000 mAh handles your S25 ~5 times, plus your laptop and wireless earbuds. At 140W output, it'll fast-charge the S25 at its full 45W rate. Heavy (~22 oz). Backpack only.
Samsung 25W Battery Pack 10000 mAh
Samsung's own battery pack hits the S25's Super Fast Charging at 25W and gives you ~2.3 full top-ups. A solid mid-range option that looks the part next to a Samsung phone. The downside is the standard rectangular brick form factor.
INIU P50 10K
INIU's P50: 10,000 mAh, 22.5W output, built-in USB-C lanyard, under $30. Best value on the list. Still a brick-shaped charger at ~17mm thick — not slim, but tough to beat on price.
Baseus Magnetic Wireless Charger 10K
With a Qi2-compatible case, the Baseus snaps to the back of the S25 and delivers up to 15W wireless. Closest thing to the iPhone MagSafe experience on a Samsung phone. Adds bulk; works best for stationary charging.
