After putting our favorite battery packs in various gift guides over the years, we decided to go all out this year and do a gift guide just for battery packs. I consider myself something of a battery pack aficionado, so I decided to step up to the plate and lay out some of my favorites.

While I’d say the two top brands in terms of reliability and price Anker and Aukey, we tried to get a variety of products with different special features and size/capacity configurations.

Remember, the most straightforward way to judge a battery pack (besides price and reliability) is by its capacity — i.e how much power it can hold. All of these devices are measured in mAh, or milliamp hours. To give you an example, the new iPhone X has a capacity of 2,716 mAh, meaning a 10,000 mAh battery pack would be able to recharge a fully drained phone a little over 3 times.
