    1st time getting one of these backup chargers. Honestly I’m glad I got this one. Wasn’t that expensive at all and it’ll charge my iPhone 8+ from low 20%battery all the way to the 90%/Full within 30 minutes just about. Charging the portable does take quite some time but it’s not a problem. Can always charge it while driving and or before falling asleep just plug it to charge. Neat thing is you can easily put the charge behind the cell while holding it during charge. Doesn’t get in the way :)

    Even though I was skeptical, the PowerCore has saved my wife twice this week. She woke up Tuesday with a 100% dead iPhone. There was no time to charge at home so she put the phone on the charger and the whole thing in her purse. When she got a flat tire, her phone was juiced and ready. She was Drafting designS on her iPad, which drains it, but it was fine because she has her PowerCore.

    I researched all options for this kind of back up battery, and even bought a different one first. I returned that one, never having opened it, because this one seemed to meet all I was looking for, and it’s great. I like that you don’t need an extra cord when you are out and about- it has the connection to connect to your phone, built right in. And it stores more than enough power for when you need to recharge your phone.

    A friend of mine recommended getting an Anker for my iPhone, so I was looking around for a little while. BB then marked it down to $29.99 because I am a Elite member. This little charger is so great, no more looking for wires except when the Anker needs to be charged. I probably get 4+ phone charges for my phone and countless for my Airpods charging case. Get this today!

    This is a nice size. Seems sturdy. No way of knowing yet if the lightening attachment will hold up to use. Seems as though it will. One word of caution-if you have an android phone, you’ll need to purchase an adapter. I got mine from amazon. Would surprise me if Best Buy didn’t have one also. I just didn’t realize I needed it until I got home. Female lightening to male C.
