Good to have on side to charge your phone to get 15% more battery. After like 15min this thing gets hot. Unplug it or it might just explode.

Small, light, efficient, no issue with performance. Takes roughly 45 min to be fully charged itself. Using it for my smartphone as an emergency backup. However, its charging capacity is limited - once my smartphone is dead, this charger will charge it up to 70% only (not 100%). Good to have another one handy or buy one with higher charging capacity. This one works similarly as Dynex™ - Lithium Ion Portable Battery Charger also sold at Best Buy.

Got this free from best buy and use it occasionally. Does what it is supposed to and have had no problems with it. Lent it to some guys who stopped in front of my house whose phones died (maybe on drugs....) and they actually returned it and it still works to this day.

I have taken this along on all my bicycling excursions as my phone really gets a workout also. This little unit will keep the phone running and I like the piece of mind knowing I don't have to worry about the original battery going dead and being without a working phone.

I found this on a for quick sale rack at Best Buy. It was a present for a young adult who always seemed to be chasing power for some portable or other. Its works for the application.

My iPhone battery is reaching end of life. Time between charging is well below an average workday. Until I can get my battery replaced, this portable charger fulfills my need to have a full day's operation from my phone. Small size easily fits in my pocket.

This is a life saver when you can't get to an outlet, I use it all the time. It is super fast. I actually bought a second one and keep one at work. It has a connector that you can charger the battery from the computer.

I need to charge my cell two or three times a day. And sometimes, I am in place where there is outlet available. One of my friends recommended to buy portable charger and I simply bought this one, because it wasn't the first time I purchased a product from this brand.

got this on special from BB and could not pass it up. Works well and its size is nice. Would be perfect if it came with its on charging brick - but I have plenty so not an issue.

This is wonderful to carry in pocket or purse just in case. My fiancee carries it in her purse with the pocket fan and this will run the fan for a long time, great on a hot day.

I purchased this for my sons phone. I wanted to give him a option when away from home after school and before practice to charge his phone because there wasn't a outlet near by.

I really liked the product and used it quite a bit. It did go out suddenly and will not charge back up. It was handy and portable when it worked.

I use this as my car charger. The cord works well to maintain a full charge on my cellphone with the USB port in the car. The portable USB port gives me a 60% when in my bag or purse.

Although this product works well, I do wish the charge lasted longer. It is good for an emergency, but it did not give a full charge to my phone before running out of juice.

This charger is handy because it is small and seems to charge fairly quickly. It does, on the other hand, charge the phone rather slowly, but is good to have in an emergency.

It's way more worth it having 3 of these than one with double capacity. You can get in the pocket bc it's super small if you are just going to be out for some hours...

Purchased it because i needed a short cord to charge my phone in the car, but got the added bonus of having the portable battery when i am on the road and need a quick charge.

For what I got it for the product is great. I spend long amounts of time outside of areas with outlets so when my phone is dying it's nice to be able to bring it back to a full charge

Decently sized. does its job as far as charging your phone. didn't like that it didn't come with a lightning cable for iPhone when that seems to be the most popular phone out there.

This battery is not as great as other brands. But considering the price, power bank size, it is okay !!... I got during some deal of the day and it is worth.
