Review: Joaao Ultra Slim Power Bank

Mobile power banks are super handy, and ultra slim mobile power banks are even handier.  I’ve been using the Joaao ultra slim power bank for over a week now and honestly I can’t believe I got along o.k. before I had this power bank in my life.  Cheesy? Yes, but true.  I have used other power banks that are smaller… which is really convenient.  But I like the POWER of the Joaao.  It’s got 20,000 mAh which means I can charge my phone 5-6 times before I have to worry about charging the charger.  That means I don’t need to worry about outlets on business trips and that I can keep it handy on the side of the couch and not need to get up to use the wall outlet.  Hurray!  But what I like most of all with the Joaao power bank is how quickly it charges my phone. With other power banks a full charge will take a few hours, but with the Joaao I was able to get a full charge in a little over a half hour.  Combine that with this being the cheapest power bank of it’s capacity available online and you’ve definitely got a winner.
