Portable Charger 5000mAh Slim Power Pack For iphone, Samsung, HTC, Huawei and more (white)
I have both battery pack sizes but I have to say, I really like how small this one is. I've got an iphone 8 plus and I get about 2 charges from the small pack. I carry the small battery in my purse and I take the larger Mogix for when I travel. I've had mine for about 8mths now and they both work great.
