Anker has discounted its very popular battery pack and wall charger hybrid, the PowerCore Fusion. This is priced at $21 right now, which is down from $26. This is only possible when you use the promo code ANKERFS1 at checkout. That takes $5 off of the regular price, and definitely makes this worthwhile.
The Anker PowerCore Fusion is a great battery pack to pick up for a number of reasons. This includes the fact that it is a wall charger, but it is also functions as a battery pack. It is a 5000mAh capacity battery which isn't all that big, but it will charge your device fully, at least once. Of course, you can plug it into the wall and charge the battery and charge your phone, since it does support pass-through technology here. That makes this a very versatile battery pack that will keep things charged up. The Anker PowerCore Fusion is a great battery pack to pick up and take on the go with you, since it is so versatile. There's no Quick Charge 3.0 here, but you do have Anker's proprietary PowerIQ Technology, which is going to still charge up your devices pretty quickly, which is definitely a good thing these days. This is a great deal on the PowerCore Fusion, and one that doesn't come around that often.
