Extra juice on the go!
925142
I love my battery pack/phone protector. It's very slim and does the job of protecting and energizing, if needed.

Because I also replaced the battery on my iPhone, I rarely have to turn the battery pack on. It's a real comfort, like insurance, knowing I have extra juice if I need it. I have had the battery pack fully charged on the unit for the last week and never had to rely on it. Each time I check to see how much energy is left in the pack, it always shows five bars, so retaining its charge.

The only very minor point against it is the top slip on protective cover which is really just for appearance. It really is not essential to the functioning of the pack but completes the look and protection of the unit. It can be a bit fiddly putting it on.

Great for on the go power! Got a different color for each of my boys, so we know who's whose!

I was pleasantly surpised that for the price, this was so easy and sturdy. I wish there was a bit more juice capacity so you don't have to dump your juice so often.

I bought two of these awesome little guys, one for myself and one for my sister and we both love it.
Small enough to not be annoying in my purse, this little battery makes it so that I'm not constantly paranoid of my iphone 5 running out of battery. Not only is this handy little device amazing for the sole reason that it charges your phone without an outlet, but it also charges things super fast. I plugged in my phone to this battery before an appointment because it was at 8%, by the end of the hour it was fully charged again, like magic.
I used to always try to conserve my phone battery when I wanted to be using it most, now I can play all the silly games I want while on an airplane and still have a charge on my phone when I land.
The battery itself does take a while to collect it's full charge so I plug it in over night, but I'm able to extend the life of my cellphone battery so dramatically, I don't like to leave home without it! I can easily get 3 full charges before this battery needs more juice.

I would highly recommend this product. Great concept and well executed.

I LOVE HAVING THE CONVENIENCE OF THE SECOND BATTERY READY TO GO!  IT CHARGES FULLY WITHIN 5HRS AND IT HAS A CHIP THAT THEY SAY DOES NOT ALLOW FOR OVER CHARGING!
 SIDE NOTE (OF COURSE I REALLISED THAT ALLOT OF MY ADDITIONAL BATTERY USAGE WAS DUE TO HAVING THE SCREEN TOO BRIGHT GO FIGURE!

I started juicing and these are perfect juice companions to take to work.  They are so easy to clean by hand as well as the dishwasher. I've been using them for over a month, daily and they are holding up great.  The only top I've had to replace is the one with the spout as the little stopper fell out and the tube started smelling too much like the green juice!

Like the extra kick this gives smoothies - and the energy kick to get things done!! (Lately I have poured the tube contents into a small container & use for two or more drinks.)

just what you need when you can not carry around an extra battery, so this is the answer! a little heavy, but not a problem.
it charges quickly with the enclosed cord - put them both in a small zip lock bag and put them in my pocketbook. now I don't have to be afraid of running out of power when I am not home.

So far so good. I'm a tiny bit concerned that the catch basket for the juice could easily shift out of place and/or get bumped easily and spill the juice, but overall this little unit is great!

Power, power, power...we all need it with our high end smart phones and tablets.  You can pay some pretty hefty prices for some of these items, too.  But why do that when a product like the OXA 7800mAh Juice Box is around.  The robust little charger/external battery measures 3.9" X 2.6"X 0.9".  it weighs just over 6 ounces.  So to put it in a nutshell the battery is small enough to carry in your pocket, purse, laptop bag, perhaps even your tablet case depending on its size.  I think that it is very important that external batteries be small enough to carry in a pocket.  Some can be quite bulky and heavy and you're just not going to want to carry them on your person.

The unit is not only lightweight but also seemingly durable.  the construction looks solid to me.  Built in chips prevent overloading or short circuiting which gives you the sense of safety and reliability.  The unit comes with two USB ports to allow you to charge two devices at once although that may be a bit ambitious at 7800mAh depending upon what items you are charging.  One USB port is rated for 2 Amps; the other USB port is 1 Amp.  A set of four LED lights indicate charge level and remaining power in the battery.  It comes with four different charging tips for various devices like the iPhone, Galaxy S4, etc...Note it comes with the cord ONLY.  Not a plug in end.  You still have to plug this into a USB charger to actually charge the battery but I am sure you have plenty of those, right?  It also comes with its own velvet carrying bag although it's not really something I will use.

I found that it charged from average to better than average in terms of speed.  I was able to fully charge an iPhone with power left over for an iPod Touch 4.  That's not bad at all!  It does not, however charge as fast as a dedicated wall charger so please take note of that fact.,  Likely good for 2 - 3 smartphone charges or one tablet charge, give or take.  You can also use this as an emergency flashlight.

I have found OXA products to be generally reliable and well made and this is another!

Going out? Traveling? Oh no you need some juice. Your phone's battery died. Your friend's battery died. My friend...this will save your life. This will save your friend's life. What you get with this is 2 USB ports. One you can share with a friend and one you can use yourself. The amount of power isn't too much. It's rated 4000mAh which isn't a lot but not too little either. You'd be able to charge your phone about 1-3 times. This thing has no power button. Instead when you plug a USB device to one of the ports, the lights flash on letting you know the power went on. Sometimes you forget to turn the power off on power banks...but with this it will be off as long as a device isn't connected to one of the ports. That's just smart. This also came with a micro USB cable in which you charge the power bank by plugging in the micro USB end to micro USB port of power bank and the USB end to a USB power source...or you can use it for your android device. It's a nice and small and portable cable. This has 4 LED lights in the front. When charging, the charging level of 0-25% displays 4 flickering lights. 25-50% displays 1 LED light and 3 flickering lights. 50-75% displays 2 LED lights and 2 flickering lights. 75-95% displays 3 LED lights and 1 flickering light. 4 LED lights are displayed when the charge is complete. Overall, I would recommend this product as it provides enough juice for you to get your phone charging and it's also nice when power banks offer an additional port to share with a friend or w/e.

Pros:
 - Black matte finish helps it from getting fingerprints/scratches.
 - Portable. Thin and flat and not too large. Fits in most pockets nicely and easily.
 - Enough juice for you to get by the day.
 - Share a port with a friend. This thing comes with 2 USB ports.
 - Smart Power On/Off Feature. Plug a device on, power bank turns on. Unplug the device, the power bank turns off.
 - LED lights letting you know charging status, etc.

This blower is great but it loves to sip on the juice.  I tend to run out of power before finishing because I also have the trimmer.  I would definately suggest wether you just have this or are getting multiple devices to buy a extra battery.  That is my only complaint.

I have used this on 3 trips and loving this battery more and more. I am not a power user, I usually charge my iphone 7 2-3 full charges on each trip and there is about 50% juice left after each trip based on the indicator lights (2 out of 4 LED). The other surprising fact is how long this battery holds a charge, it can go weeks without losing charge. I checked it 3 weeks after my most recent trip and there was no change in lost charge based on the indicator light (2 out of 4 LED). On my most recent trip, I charged my iphone 7 twice, my girlfriend's iphone 6 once, and 2 GoPro batteries and probably had 30-35% juice left in the power bank (2 out of 4 LED). I love the functionality and design - there are 3 things that I wished this power bank had: 1) Water proof-ability, 2) Digital indicator, 3) an LED light but I think i am being too demanding :D

I have used this for all of my juicing needs lately.  Super easy to use and to clean up.  I love the fact that the grate inside of it catches the seeds and extra pulp if I want it too.  I should have bought one sooner !!

Purchased as an extra battery for my cordless floormate when juice runs out in the middle of cleaning.

This fits under the seat of my car. It has all the juice I need for charging a laptop and powering a 12" fan while out in the woods. The USB is nice too for my smartphone. I use the cigarette lighter plug for power in, but am considering hard-wiring it once I can find an always-on power line to tap.

The Mophie Juice Pack is an excellent product with great quality too it.  Light, durable, and perfect for "on the go" types.  I am student and I am also a worker so if you are the type of person who is busy, likes to listen to music on their IPhone, or more,  this is a great investment.  Totally worth the price as it gives you the best bang for your buck.  The days of carrying around a traditional IPhone charger is done as this should do the trick.  Just be sure to charge it over night or whenever you have down time.  Again, excellent investment!
