Good charger! A bit bulky
Color: White
I bought this over two years ago for my parents to use on an international trip. They told me that it was useful. Since that trip, this portable charger hasn’t been used by anyone, but I recently found it and decided I wanted to use it myself. Because it hadn’t been used in so long, there was a glitch in the battery where when I tried charging the charger, it decreased to 0% on the screen instead of increasing to 100% and that’s when I learned that I had to reset it. After resetting the charger, I was able to fully charge the battery to 100%, although it did take almost an entire day. I’m not sure if it was because the charger hadn’t been used in so long, but I’ll have to charge it again later to see if it still takes that long. I will say that my phone was recently at 1% and I used this charger and it got my phone to almost 60% (pretty quickly) while only using 30% of its life battery which I think is pretty impressive. To me, this charger seems to be worth your money because you get so many cables for different types of devices and I found that it charges quickly. The only downside so far is that it is a bit heavy and it did take a while to fully charge the portable charger the first time. ... show more

Great!
Color: Purple
Love this little power bank. Bought because my friend has one. Really does charge fairly quickly - not a fast charge though. Does power up well and has a display to tell you how much power is left in it. Comes in a nice little case to keep it in your purse or bag so the cords don't pop out. Perfect back-up power for your phone! Great for long road trips, heading out to football / sports, or kids at school! ... show more

Fast, compact, easy to use. Great pick.
Color: Black
Always like a backup plan, and this fit the bill. The unit charges quickly, and charges most of my electrical items. Very versatile, with a nice digital readout. Powers up quickly, and it fits comfortably in a pocket, and comes with a nice carrying bag.

Excellent Portable Charger!
Color: DustyPink
I absolutely love this portable charger! It’s convenient, lightweight, and perfect for traveling or everyday use. The built-in charging cables are a game changer because I don’t have to carry extra cords. I also love the digital display that shows how much battery power is left. The pink color is beautiful, and the ability to charge multiple devices makes it even better. Great quality and value for the money! Highly recommend! ... show more

MUST HAVE
Color: Red
LOVE! Will be buying another. It’s small and convenient, charging power is great can last hours. Love all the charger options. I wish it didn’t take all night to charge but at least it charges my phone rather quickly so it balances out. Highly recommend, especially if you’re out a lot.

Perfect and purple!
Color: Purple
I love these. I have two. I'm not sure where I left the last one, so I bought another. I love that all the cords are right there, and it doesn't matter what I need to charge: phone, fan, or anything else. I have what I need. I also like that the design is not cumbersome. It travels well with my phone. I take it camping, to the swim meets, and more. I'm not the only one using it; it often gets passed around when others need a charge. The battery works well. The price is good; I had to check it again since I was replacing the last one, which was tucked away somewhere in a backpack. I would recommend this purchase, and it comes in purple! ... show more

Game changer!
Color: SkyBlue
I absolutely love this charger! I bought several as stocking stuffers for everyone in my family last Christmas. I use mine all the time. I love how it shows how much battery life is left on the display screen. I also love the fact that it will connect to virtually any device! It has gotten me out of many jams this past year. Also love the variety of colors, I got everyone a different color to easily keep track of whose was whose. Money well spent! I would definitely buy again! ... show more

A staple in my purse
Color: MGreen
This portable charger has been such a convenient thing to have, especially when traveling or spending a full day out of the house. My favorite feature is definitely the built-in cables! I love not having to remember to pack extra charging cords because everything is already attached and ready to use. The 10,000mAh battery provides plenty of backup power, and the charger is compact enough to easily keep in a purse or bag. I also really like being able to see how much battery is remaining instead of guessing when it needs to be recharged. This is especially great if you have an iPhone with a battery that doesn't last very long and your phone is chronically dead by lunch😂. It's so nice having a backup charger with you without needing to carry around a bunch of extra cords. Overall, this is a great all-in-one portable charger for travel, busy days, or just anyone whose phone always seems to be running out of battery. I would definitely recommend it! ... show more
