Samsung 25W Wireless Portable Battery

The Samsung 25W Wireless Portable Battery features the same 10,000mAh capacity we’ve seen in other generations. The difference here is in speed. This time around, Sammy has produced a portable battery pack with 25W charging, and this applies both for charging your device and the power bank itself. It’s one of the best power banks for Samsung devices.

What separates the accessory from Samsung’s other power banks is right in the name: Qi-compatible wireless charging. The battery supports up to 7.5W wireless fast charging output to compatible Samsung smartphones. The Wireless Charger can also charge other Qi-compatible devices. You can even use the power bank as a regular wireless charging pad at home. It has a couple of USB-C ports for charging devices too.

Wireless charging is great, but many of you prioritize battery capacity over excellent features. Samsung has a great alternative with twice the battery power and 25W output. It’s also pretty versatile, thanks to its three ports, of which one is a USB-A port, and the other two feature a USB-C connection.

This option is for those who prefer nicer aesthetics and a much smaller profile, even if it means sacrificing some battery capacity or fancy features like wireless charging. The Samsung 25W Portable Battery has a capacity of 1,000mAh and can provide up to 2-3 charges for most smartphones — depending on the battery size. It has both a USB-A and a USB-C port, as well as light indicators to see how much juice the power bank has.

As if that wasn’t enough, the portable battery comes with an AC outlet with max speeds of 100W, given that you have the right charger to handle blazing speeds. It also comes with a 20,000mAh battery, which is plenty of juice to charge your phone multiple times.

If money is no object and you want a blazing-fast battery pack, it’s hard to beat the Anker 737 Power Bank (PowerCore 24K). It’s packed with Power Delivery 3.1, and has a stunning max output of 140W. The integrated display makes it simple to monitor everything, and you can store 24,000mAh of juice. It’s not cheap, but it should charge your Samsung devices very quickly.


How fast a Samsung phone charges depends on the fast-charging technology it supports. For example, a Samsung Galaxy S22 Ultra can charge at up to 45W. This means it can charge from 0% to 100% in about an hour. Of course, that is given that the portable battery pack supports these speeds.

It’s possible to charge your portable battery pack while it’s charging other devices, but the unit needs to support it. The feature is called passthrough charging. Look for it in the specs or features.

While these modern high-end portable batteries are getting very advanced, they can’t always charge or power all devices out there. The best portable chargers can usually handle about 200W, which would be your most significant limitation. For example, most desktop PCs use far more than 200W.

It’s not recommended to leave power banks unattended when in use. This is especially the case if you’re using fast charging, as faster charging can heat up both your device and the battery.

Samsung-focused portable batteries are great, but plenty of general options will also work amazingly with Samsung phones. Check out our other recommendations for the best overall portable chargers and great options for USB-C users.
