... is my second Anker charger and I am very happy with this brand
This is my second Anker charger and I am very happy with this brand! My first one lasted over 3 years and still works but is on its last leg. I bought the 20,000 because it was at a great price that I couldn’t turn down and about 7,000 more capacity than my previous charger. I also loved how slender it is vs my old one which is thick and wide. My only complaint is the weight of it. I thought with technology improvements over the years that they would have figured out how to make them lighter but the new model is still quite heavy at 12.65oz which is 2oz heavier than my previous model. It’s not the biggest deal because it’s worth have an extra long battery life without having to constantly re-charge your spare battery. I also love the battery life indicator wheel which has 8 dots instead of the 4 on my previous model. The battery indicator wheel is so much easier to read now and I don’t have any issues trying to figure out when I’m running low on juice. The battery came with a nice bag with a drawstring so it doesn’t get all scratched up in the bottom of my purse. I also really appreciate the outter shell of the battery being matte instead of shiny like my previous model so I am hoping to show even less wear on it as the years go by. The battery charges quickly and is long lasting. I will update my review if anything else arises but so far so great!!
