Best power bank for the Galaxy S9 and the Galaxy S9+

Your quest for the best power bank for Galaxy S9 and Galaxy S9+ ends here. There are quite a few options available for customers who want reliable external battery packs that they can carry around with them and charge their new Samsung flagship as and when required. This list has some of the best options available right now that provide the good value for money.

Many customers will think about purchasing an external battery pack for Galaxy S9 after they pick up the device. That’s because the Galaxy S9 and Galaxy S9+ have the same battery capacities as their predecessors and official Galaxy S9 battery life stats aren’t that different from the Galaxy S8.

Battery cases vs power banks: What’s better?

It depends on your preference. External power banks tend to have higher capacities and they can be used to charge multiple devices. You can chuck one in your bag and forget about it. Battery cases snap on to the device and add significant weight and heft to it. Sure, you can charge up the device and then take off the case but then you’re left without protection on the phone. With an external battery pack, you can use any case and simply disconnect it when you don’t want to carry it around. Moreover, heavy users can get multiple charge cycles out of an external power bank while most battery cases are only good for one full additional charge cycle.
