I have used more expensive brands and the myCharge is as good or better than them. It's lighter weight and thinner (therefore easier to carry). Definitely a good find.

I bought this item because I didn't like the bulk of my iPhone and iPad plugs. This item will recharge a completely drained phone or tablet quickly three to four times. I am extremely pleased with this item.

I own other battery packs but this is the best. It's a good balance between size, weight and capacity. it will charge my smartphone quickly with no problem and it shuts off when complete. I have other high capacity battery packs, which also shut charging is complete, but will shut down immediately when charging a small item such as a bluetooth headset. This charges everything from an iPad mini down to a bluetooth headset. Great product.

This portable battery worked fine. I took it on our trip to Italy and used it to recharge our phones while we were out for long days taking pictures and using the internet. I like that the device has the capability to charge two devices at once. It is slim and light and easy to carry.

Just the Charge I needed

I was happy to find this utility by a trusted brand. Not only does it itself charge quickly but it also charges my phone pretty quickly. I'm glad that it has 2 USB ports not only to charge two separate device but also two completely separate cell phone providers: an iphone and an android phone for example. It's small enough to slip into a messenger or travel bag for on-the-road convenience. My only knocks against it are that (1) the cable that connects the battery to charge is for USB not a standard wall outlet. This isn't a problem for me because the multi-tap I have just so happens to have two USB ports however, seeing as how this isn't mentioned on the box could be a problem for someone one might need it to be plugged into a wall. (2) the cable to charge the battery could be a bit longer. Again this wasn't a problem for me but others purchasing this item may need a longer cord to accommodate their space needs.

I bought this device because I travel the country for work and frequently run out of juice before I get to the hotel. I haven't been on a trip yet, so haven't tested it thoroughly, but have used it - it works and it works well! It charges quickly, it charges fully - took an iPhone 5S from about 10% to 100% and still had juice left. I REALLY like the dual charge ports so I can refresh both my iPhone and iPad simultaneously. It's compact, and lightweight so it doesn't take up much precious cargo space in my backpack and seems durable enough that I don't have to be concerned about the backpack being tossed around. I looked at several other emergency chargers - this one was well below the cost of similar products, but had superior reviews - no-brainier there - here's another good review!

I have used the myCharge RAZORMAX multiple times. It charges both my iPhone and iPad quickly, with plenty of power in reserve for additional charges. I was out the other night at a bar, and two of my friend's phones were basically dead. I said, "Hold on!" I ran out to my Jeep, and grabbed the charger. With the 2 USB ports, I suddenly became Zeus... a god to my group of friends. Ended up charging 4 phones that night, and still had power to spare. Well worth the investment!

I bought this charger as a emergency power source for my wife as she traveled cross country. The unit lasted a continental flight plus 5 days before it needed to be recharged. It is relatively light weight
(its over all weight is its only downside), slim and roughly the size of an Iphone 6. Most importantly it is a workhorse, it charged both my wife's Iphone 5s and the Ipad (Gen 1) once before it needed a recharge. We now do not travel without it, especially since we live in a heavy snow fall area it provides extra comfort that we can still charge and use our phones.

This has been a great accessory to my S6! Small, thin, solid design, and very portable. Fits perfect in my golf bag! Fits perfectly in the golf cart cup holder along with my phone while charging. After 18 holes of golf while being synced with my Bluetooth speaker, streaming Pandora, and using my golf GPS app., my phone is ready for the rest of the day. Suggested improvements might be: fast charging, and waterproofing. A must for power consuming junkies like me!

Let get to the nitty gritty.
The bank charges a battery in full in about 30min. (Note 8 3300 mAh batt)
BUT it will drain the battery capacity nearly 80-90% meaning that if you use the available 2 usb ports, youre lucky if you get 40% charge for the plugged in devices.
Its light. I traveled to vegas and this little guy was a life saver, its the size of an average wallet and it ONLY comes with a micro usb cable for charging purposes. Make sure you provide your OEM phone cable. I noticed on both apple & samsung devices the fast charging feature does not work unless you have the oem cable. The same for vehicle charges
Overall, im very satisfied with this device. Its lighter than my other mycharge products, it fits in my pocket and i can hold it together with my phone, its very versatile. Yet I was suprised of the limited amount of holding capacity on the unit.

Very impressed with power bank, easy to use, shows how much power you have left, enough power to charge my iphone 6-7 times and it doesn't weigh much plus it's compact so it makes carrying it around very easy. Very satisfied with this purchase :)

Gave New Life to my iPhone

Don't know why I waited so long to get an external battery so that I can actually use my iPhone as I want to instead of avoiding things that drain the battery. I like my iPhone but hated the fact that with fairly minimal use, I still had to waste time finding somewhere to charge it.
I bought a case for a GPS at the suggestion of the very helpful man at Best Buy and keep the battery and a variety of cables in it. Now I can use my phone without worrying that it's going to die before I finish a conference call.
I haven't tested it, but am pretty sure I can fully charge my phone at least twice before having to charge the external battery.
It's light enough that I can put the battery in a pocket and use my phone with a 3' cable while it's charging.
Thought about changing phones due to iPhone battery but now have no need to.

Charges very very fast and lasts a long time. Went on a trip and was able to charge 4 iPhones on this throughout the day. Have even used this when traveling out of the country. I highly recommend this portable charger. It is also very slim and practical-not bulky at all but definitely durable. I have had this for 2 years now. I rarely write reviews but I recommend this product to everyone!

Best capacity and best quality available in this small size. Love that it has dual sub ports and can charge/power two devices at the same time. I use it for cameras in addition to tablets and phones.

I really like this portable battery. It charges quickly and holds that charge for a long time if not used. I like the indicator lights that show how much power is still in the battery. It's slim design makes it great for a small purse.

Top quality, rugged and has the capacity to recharge your phone a couple times over or two devices at the same time for one complete charge each. Easy to use and small enough to fit in a pocket or purse. Feels about the same as carrying a second phone and very reasonably priced. I liked it so much, I got a second one for my wife. After comparing several brands and models, this is my top choice.
