    This is the third phone recharger I've had to purchase from this company. The previous to the cord always went out exactly one month after the warranty went out. Best Buy would not honor the warranty. They said it had to go back to the company for their warranty. This charger seems to be working OK only because I installed my own cable into the side. So if the cable breaks I can replace it . it works, it does it's job, plugs in the wall to charge, no need to have a USB plug into your computer.

    the product is reliable and works for a few hours. It is strong and change does not wear out fast lie other products do.

    The size is big, but that means it can fully charge 2 devices at the same time.

    I have purchased 3 of these and they all work fantastically. They hold about 4 charges for my iPhone 6s. They hold their charge when not using. They have wall prongs in the back to plug directly into an outlet so you don't need to worry about a micro usb cable and power block to charge. I highly recommend!!

    Good choice for mobile battery pack

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    The main reason I chose this model is that it features a wall prong for charging both the pack itself and the connected device. It makes it perfect for travel, no more carrying one charger for my phone and the other for my battery pack. It is heavier than I would like and the weight can cause the pack to droop in more worn sockets.

    Great 2-USB Ports Portable Charger

    I wanted a portable charger that plugs into the wall, and I am very happy with this one. I get 2 full charges out of it for my cell phone if I only use it for that. It also has 2 ports for charging 2 items at a time. It's a little big for my pants pocket, but it fits just fine in my purse. A good purchase!

    Have used it twice in 30 days. It seems to hold a full charge well. My goal is too find how long of a period it can go between uses and maintain 90% or more for the real emergency when it happens. Will do a performance follow up in a couple of months.

    My family and I needed a portable mobile phone charger for a trip that we will be taking soon. We will use this charger during our vacation as a means of keeping our phones available to communicate with each other. This charger will be very helpful.

    This thing is lightweight, can charge 2 phones simultaneously or get you 2 full charges. It doesn't take long to recharge and has been very useful for me. I'm an avid app user and run my phone battery down often so this is a great tool for me.

    One Charge for Note5

    I am using this portable charger on a Note 5. It gives a single full charge while in use. That charge and use drains the portable battery to the last signal light. A little bit too bulky, plus I need to carry a separate cord.

    I have been through several of these Chargers in the past and never had a whole lot of success but this one has been exceptional. It keeps my phone running and recharges it quickly.
