Anker has put one of their most popular battery packs on sale this week, the PowerCore 15600 Battery Pack is currently on sale for just $17.49 when you use the promo code SPRING79 at checkout. This price is available now through March 4th. This battery pack is priced at $25.99, so it's a pretty decent discount on this battery pack overall.
Now this model here is not a Quick Charge model, so you won't be seeing those fast Quick Charge 3.0 speeds on some devices, but it does do fast charge. The battery pack essentially talks with your smartphone to find out how much charge it can take safely without damaging the device, and it will output that much. Each of the two ports here output at up to 2.4A, which is still quite fast, and you'll be able to charge up your devices fairly fast. Anker also has a set of LED lights on this battery pack, which will indicate the amount of juice that is left on the battery pack. There are four here, so each one is roughly 25%.
This is a great portable battery to take with you on a trip, especially if you'll be away from an outlet for an extended period of time, as it'll charge your phone up about 4-5 times before needing to be recharged itself. And coming in at $17.49 is an absolute steal. Don't forget to use the code SPRING79 at checkout to get that price.
