    This was great for a day sightseeing when I didn't have access to a plug in. Discovered you must use the official charger cord (not an off brand I also purchased at Best Buy) or iPhone will not charge from this device.

    This is a very good product and serves a vital need to those who need to charge their device when away from a plug. The charger is good for charging while travelling or in an emergency. This Dynex charger has to be one of the best and most useful items I've purchased.

    This spare battery saved me a few times on my vacation when I didn't have a car or wall plug to recharge my iPhone. The only complaint I have is the manufacturer should have upped the mAH to give a few more charges.

    I purchased this for my wife as she travels often for work. On the news, we saw that their was an issue with people using public charging stations as places to hack other people's cell phones. With this, she was able to keep her phone charged all day without using the public access points. She simply charged it at her hotel and was ready for the next day. Worked great! Only wish is that it came with it's own AC charger. But we have extras so it wasn't a big deal.

    I purchased the Dynex lithium battery to increase my phone time on a recent flight, but it turned out to be a lifesaver. After driving my daughter back to college I had a flat tire on the highway returning home late at night. My smartphone battery was almost gone and I remember I still had the Dynex in my purse. It gave me the all the juice I needed to get home safely.

    Husband needed something to keep him charged consistently as he is often located without an outlet. So far it is working great. We'll have to wait to see what the longevity is. But happy with it currently.

    Purchased this charger while on vacation. I was constantly on my phone using the camera or texting, so towards the end of the night, my phone was almost dead. I am so glad I purchased this charger because I was able to carry it with me during the rest of my vacation without having to think twice about using my phone in order to save the battery life. The only downside is that it can get a little heavy in your purse after awhile.
