This product is great! It works really well. I love that I can plug this straight into my phone. I don’t need any cords. The only downside is the charge for the actual device only helps my phone charge to one full battery. Before I need to charge the actual device. I still love this product!
It’s great for traveling without the USB cord and it’s perfect to put in your purse or pocket. It also charges my phone in minutes!!
Great charger with excellent battery life. Charged cell phone, iPhone, 4 times with this and it didn't make a dent.
Love this. Works amazing. It's small which to me is great. Just charge it and attach it to your iPhone and go.
Fantastic product!!! Works great! Recharges fast and is small enough to easily carry! Perfect!!
Love the product! The best part is you do not need to carry a cord with you.
Good for the price. Wish there was an indicator of how much battery was left.
Perfect for everyday. I charge It in my car , and use it as needed.
Wow!! Finally a light and convenient charger!!
