Bests & Worsts Reviews from Amazon

We purchased two or three of these and for several months they worked really well. However now we cannot charge them at all. Hopefully someone from Anker reads this review. Update: Following this review I was contacted by Anker and they sent out two replacement batteries. The batteries worked well for 10 months then wouldn’t charge and we did in fact recharge with an Anker multi charging port (works great no problems) and Anker cable. Maybe these backup batteries only last a bit less than a year or so, though that’s not what I expect as a consumer. Otherwise, Anker puts sells solid speakers we own, among other Anker products. This is why I’m so disappointing about these backup chargers.
