Running out of battery stinks, especially on your smartphone and doubly so when you’re nowhere near a charger. That’s why the power bank business is booming with hundreds of products across dozens of manufacturers. It’s also no secret that mobile accessories like battery banks are often deeply discounted for events like Amazon Prime Day. Samsung is no exception to this rule, and two of the Korean tech giant’s portable battery packs are on sale for about 31% off. Spoiler alert, one of them has wireless charging capabilities too. 

The two batteries only have a couple of small differences. The smaller one features 25W charging, 10,000mAh of capacity and two cable ports. Samsung says the extra port is for charging your wireless earbuds alongside your phone, which is a good idea. It also comes with a wireless charging pad, so you can rest your phone on the bank and get a charge that way. 

The larger one features 45W charging, 20,000mAh capacity and, somewhat weirdly, omits the wireless charging found on its smaller sibling. Samsung makes up for this discrepancy by including a third charging port. 

Both devices have a fairly good discount as well. The 45W version is $38, down from $55, which equates to a little less than 31% off while the 25W version is $31, down from $45, which is just a little more than 31% off. 

Samsung clearly designed these for Galaxy devices, per the product image above. However, it should work with any tablet or smartphone. You just might experience a reduction in charging speeds because the Super Fast charging standard is specific to Samsung phones. On a positive note, Samsung claims to make the battery banks out of recycled materials, which is always a plus.

It shouldn’t come as a surprise that Samsung’s accessories are built for Samsung’s products. If you’re here and you don’t have a Samsung phone, it’s OK. We have a whole list of portable chargers specifically for Android phones and also iPhones that you can sift through. These include power banks and MagSafe chargers, so you should be able to find something you like. 

Why this deal matters

For starters, first-party accessories are almost always more expensive than third-party accessories, so the opportunity to get a Samsung-branded battery for your Samsung-branded phone and accessories for a discount is a win. You can use any old power bank on just about any old phone these days. However, the inclusion of Super Fast charging on both battery banks and the wireless charger on the smaller bank presents a unique value proposition for Samsung phone owners. The 45W Super Fast charging is usually only attainable on a wall charger, so having those speeds in a portable package is a nice upgrade from the standard stuff you see online.
