I finally found a website to purchase portable power banks in Kuwait. I usually buy either Anker o Aukey portable power banks, because I believe they are the best in the market. Especially the ones with Quick Charge 3.0 to charge my phone faster than usual. A Store is a website that sells mobile accessories, power banks, and more. The pricing is great, and it is much cheaper than other stores in Kuwait. I just ordered 2 power banks, 1 from Anker, and the other is from Aukey.
