    I bought two several years ago for my wife and daughter. Emergency charging of their phones while taking a lot of pictures on vacation and sporting events worked perfectly.

    We used these power supplies to run microcomputers. The battery lasts a long time which allowed us to run our tests overnight without losing data

    So far we cannot complain regarding this portable charger. My wife uses it most of the time. She carries it in her purse for a quick charge when we are on the go.

    WHEN I AM IN A PINCH... AND MY IPHONE BATTERY DIES..... THIS LITTLE DEVICE SAVES MY LIFE!!!!! IF YOUR BATTERY DOES NOT LAST YOU THE ENTIRE DAY... LIKE MINE DOES NOT... THIS WILL BE A COMPLETE LIFE SAVER FOR YOU! IT CHARGES MY IPHONE 7 PLUS TO 70% FROM COMPLETELY POWER-OFF DEAD STATUS IN NO TIME AT ALL!!! JUST MAKE SURE YOU CHARGE THIS ITEM ALONG WITH YOUR PHONE EVERY NIGHT!!! AND BRING IT WITH YOU WHEN YOU LEAVE!!! BEST IDEA IS TO PLUG IT IN WITH YOUR PHONE AT THE SAME TIME AND TAKE IT OFF THE CHARGER WITH YOUR PHONE AT THE SAME TIME AND PUT IT IN YOUR BAG RIGHT AWAY.... IF YOU FORGET IT AT HOME- IT WILL NOT DO YOU ANY GOOD!!

    The size is nice i like that it is not too heavy or bulky. My pet peeve is that there are no buttons to push to see what how much juice it is left when it is resting so you have to shake it so the lights will light up.

    Razormax battery backup charges quickly and holds the charge until you need it. Previous charger I owned discharged over time and never really fully charged my phone.

    Granddaughters loved the razormax power banks. Great for plane and car trips where a plug-in power source isn’t always available. Very reasonably priced gifts.

    Great battery life for such a small battery pack. Don't overspend on a mophie, this charges my phone at least 3 full charges and for less than half of the cost of a mophie.

    We took this with us to keep our phones charged while using the Disney app in the parks as it can be difficult to find anywhere to charge your phone. Worked well and was convenient.

    Like this because you can charge 2 items if needed. I travel extensively and this is a must to have on the road. Charge it at night and you have a backup all the next day if needed

    This is convenient, for travel or other times, when it's difficult to find an outlet to re-charge (for me, phone or Kindle). Recommended to me by store rep.
