    Packs some POWER

    This keychain is a convenient accessory to carry in your pocket, backpack, or purse. I was so impressed with its performance that I decided to purchase a second one. This small charger is remarkably efficient, capable of charging your phone within an hour or so. It also recharges quickly. While I have several MagSafe chargers that are convenient, they tend to overheat and slow down the charging process. In contrast, this keychain doesn’t overheat or damage your phone. It effectively fulfills its purpose. Considering its price (around $20), it’s an easy decision to make.

    Best charger for busy moms!

    I am so happy with this product. As a mom of 8, my phone is constantly being used and I have to charge it at some point in the day. This charger has saved me multiple times now. Its clipped to my keys or my diaper bag every morning, and i have used it almost everyday since i got it. Fast chargin, lightweight, small, it charges back up quickly. We have bought pr been giftsd many portable chargers, but they are clunky and you need a plug. I bought this one because of the cord being attached.

    Perfect portable charger for working on the road

    I often fall asleep without charging my Apple Watch and can only get a little bit of charge in the morning before leaving for work so this portable seemed perfect for and so far it has been and the price was worth giving it a shot. The Apple Watch charges really quickly and the phone stays topped up during the day. I love that it has the internal lightning cord since my work phone is my only Apple device that still uses the lightning charger and there’s not as many of those around the house anymore. I also like the digital battery life display. I haven’t had the need to use the key ring yet but I could see where it might come in handy at some point. I’ve only had this product for a couple weeks so far, no issues or complaints and it’s exactly what I was looking for. I would buy this again and recommend to anyone who has an Apple Watch and doesn’t always have access to a wall charger.

    Handy portable charger

    Really nice, fairly compact charger. I keep one in my purse at all times. I was able fully charge my iPhone and Apple Watch with some power still left in the charger. Has a key chain that would make it super easy to attach to backpack. Type C charger and Apple Watch charger built in - no need for any extra cords.
