I was taking a bulky pack plus I had to take a cord. Now with this little pack I just take it"”the cord and both Android and iPhone plugs are built in. Get one"”you will love it!!!

This is so far my most favorite power bank. It is a tad bit bigger than a credit card and slimmer than a regular iphone. I would say that this is by far the smallest and slimmest power bank that charges my phone not only as fast as a plugin charger (in two hours my phone went from 17% to 100%) but also silently and without any kind of connection issues. It comes with male micro USB plug but comes with a mini lightning adapter that is kept safe under the attached charging cable so that it does not fall out when the charging cable is securely in its place. At first I had trouble putting the cable back into its place but all I really needed to do was to just gently press it against the slot and then push it in. It does emit blue charging light as it is working, so it may be annoying for some. I really really like this product.

I like this little gadget. It doesn't store a lot of energy, but is just right to take along in case of emergencies. My phone is temperamental, and has been known to allow itself to be suddenly drained. So I like to slip this into a shirt pocket and take it along. If I know I'm going out all day I will take one of my larger banks along instead, but for short trips this is perfect. I like the cord built in to the package, but it does take a little practice to figure out how to easily put it back with done with it. One you figure it out it is no big thing.
11-1-22 I'm going to add this little bit. I still like this power bank, but I have noticed that it seems to lose charge more rapidly than other power banks I own. What I usually do is plug the charging cable in about once a week just to make sure it is topped off. I wonder what Atom Tech is going to do now that Apple is being forced to use USB-C for charging. Dragging along a micro USB to USB C adapter plug would be a pain.

These are very compact . They are mini usb, but come with a built in adapter to convert to lightning for your iPhone . I bought these for a specific mini usb purpose, but it was nice to have that iPhone lightning adapter to use.

5 stars from me. Good purchase

I purchased this specifically to keep in my purse so I can charge my Kindle Paperwhite on the go and it works great. It's small - maybe 1/4 inch thick and the size of a credit card (I've attached a picture of it with my Paperwhite for scale) - so it fits perfectly in my purse and doesn't take up much room. I absolutely love that it comes with the cord already attached so I don't have to drag around an extra cord and the length is just enough (about three inches) so I can charge my Kindle and hold the charger behind the Kindle while continuing to read. The cover of the charger has a leather-like feel so it doesn't slip around when I'm holding it which is also nice.

Charging the unit is fast and easy and using it is just a matter of gently pulling out the little cord and plugging it into the item. There is also a tiny iPhone adapter inside, which you sort of stick the end of the regular charger into until it clicks and then you can pull it out to use it. From a full charge I've found that I can charge my Paperwhite fully twice, or my iPhone once, which I was pretty impressed with considering the small size of the unit. When it's providing power the light lights up blue on it so you know it's working.

As for durability, I use this about once a week and I've had it for about two months now and it's working fine. The cord is still secure and it charges and provides power nicely.

Overall, this is a great size and has good power and I definitely recommend it.
