hi, i am hunting for a power bank ulgently for my tablet, however, i found the selection so confusing and very few of products on line available and meet my special demand!!!what the cuss i am! well, i look for such power products for trips where i am not near a wall outlet. It's highly recommened that the product is wireless and i don't need to bring any charging cords with me. I found one on this website: www.koeok.com , the product is built right into the charging and tucks away nicely. but to my disppointed, there is minimum order limit on it, please give me any other opinions or recommendations to buy a power bank!! any help will be highly recommened!!
