If you're having charging troubles with your phone - this, along with an external charger, is a pretty solid alternative. Much longer battery life than the stock battery (especially if the stock is old).

I recently purchased the 24,000mAh battery because we lost power one day while I was working on my laptop that has a broken battery and works on AC power only. I thought this would be a great lifesaver in situations like that and I was right. I enjoy the fact that the battery has an AC plug in addition to USB ports. I was able to get my work done and charge my phone at the same time. A real joy to have and use. Definitely recommend.

I bought this charging unit with two batteries for my Samsung Galaxy phone. I'm on my phone all the time, it's my office-away-from-the-office most important piece of equipment. I chew up batteries pretty fast, and had a similar unit for my previous phone. I love being able to swap out batteries before I go to bed, put phone on its charger and battery in its charger, and, in the morning, knowing I have enough battery power for a full day.  I'm buying another unit today because I left the charger behind in my hotel room and it hasn't been found. I just know I can't get along without the extra battery power.

I rated this product at 4 stars because if you move the charger around with the battery in it, the battery will fall out. This would be a five star product if the battery snapped into place and stayed there until you took it out. This would be an ideal fix for travelers - you could put it in your bag or carry-on and recharge where ever you happen to be.

I did not experience any of the problems other reviewers did with phone over-heating or batteries swelling. The original battery at full charge lasts 10-15 hours, depending on apps used. The replacement lasts 8-10 hours. Considering I have to sleep once in a while, that's pretty good coverage for my hectic days.

The 9-volt battery jump-start worked on my Milwaukee NiCad battery like a champion. This little trick saved me the expense of a new battery and it is wonderful. I had two batteries that came with the original purchase and have purchased two more since I have owned the Drill Driver. I am a thrifty type Yankee so I never throw any thing away until I am convinced that all hope is gone. So now, thanks to DB I'll have 4! Functional batteries! Almost better than Christmas, its tax free and legal to boot.

Actually, I was planning to make a drawing and submit it to Digi-Key to have some cells configured for the battery casings as replacements but now I can procrastinate a little longer. Has anyone gone to the trouble to do this him or herself? I see some web sites that do exchanges but was put off by the shipping expense.
I'm not an EE so I'm wondering why not just go all the way and do it with lithium-Ion cells using the same charger. Any comments on that

This is a fantastic product that will leave you wondering, "Why the heck didn't I do this sooner?" No, the batteries don't last as long as regular batteries, but just keep enough so that you can keep rotating them out and you'll never skip a beat. It quickly becomes residual income, plus it's great to stop dumping used batteries into the garbage and, ultimately, into landfills. The other great things about this particular charger is that it not only comes with pre-charged batteries but it also fits AAA's!

This thing is great.  One of the main reasons I bought a note 4 over apple is the removable battery.  This thing basically has its middle finger up at iphone.  Charge your spare battery with this using your rapid charger. It takes me all of 2 minutes to swap batteries with a case on my phone.  This is a great solution for those that often find themselves in the yellow for battery life.

I like cameras with special high powered battery packs, but I also realize that is a risk if I run out of juice.  Having this as a second battery pack for my Fuji Z1 was very helpful to keep me going in times when my primary ran out of juice.  That was a rare occasion, but when it happened, this keeps you going.

I have an iPhone 4S and an iPad cellular.

I just can't say enough good things about battery power pak. It's fabulous. A little heavier than I thought it was going to be so I can see carrying it in a briefcase/suitcase/backpack rather than a purse (which is what I was really hoping to do).

The one drawback I've found (and it's only one)...the little tabs that cover the USB output slots are fingernail chippers.  They do loosen up a bit over time.  I use the USB plug itself to pop the tabs up. Then, the BIG ISSUE, at least for me, and I have small hands/fingers, those tabs are a pain to move out of the way so I can actually plug in the USB cord.

Now, I have a military grade cover on my ipad which also has movable covers on ports, camera lens, etc. They are also graded as water and dust resistant. They are much more flexible and rotate out of the way much more easily. So, I have some basis for comparison.

However, that's my only complaint.

I love the fact that it came with a great charge on it so it only took about two hours to fully charge up.

That it is pretty much encased in its own "otter box" is a bonus beyond compare. Orange? Meh! I'd prefer black or gray, personally. Something more neutral.

I took it with me to New Orleans for Mardi Gras. I was there for two weeks.  Some days I was on the parade route for up to 15 hours at a time, that's not an exaggeration. This little gem totally eliminated the need to ration my phone use.
I was capable of texting to my hearts content, using the parade tracker, listening to music, reading during down times and talking on the phone - all without worrying about my battery dying.

After charging my phone three times - all three times I let the batter level drop below 35% - The charge on the battery pak itself had only dropped to three LED lights. I'm beyond thrilled.

I would recommend this product for anyone who travels. Anyone who lives in hurricane territory or tornado alley (I've done both). There's nothing worse than being in day three of a power outage from a hurricane and not knowing where to go to charge your phone.

It would be great for travel and unexpected breakdowns (where did that car charger go?).

Students. Business travelers. That RV, tent camper, scout troop, etc.

Seriously, this gadget is the best!

First thing I did of course was run my iPhone down to zero and plug it in.  It registered that it was charging immediately--on a cloudy day--and was charging fairly fast, though I didn't let it charge the phone the whole way because I needed it.

And that brings me to what sets this device apart.  It comes with this four AA battery charger pack, and the battery pack is actually a charger as well.

So what's REALLY, REALLY COOL about this?  Most likely you're going to want to use your devices all day long, and that's when you need them to be charged up, but if they're on the charger during the day then you could only use them at night when you really don't need them.  So instead, what this set offers is the abilility to charge the battery pack during the day, then plug your phone into the battery pack, which can charge up an iPhone in only an hour.

Especially when the power is out, and you're desperate for some way to communicate with other people or just entertain yourself, this is a life saver.  And in a real emergency, during a power failure, it can genuinely be a life saver--enabling you to contact emergency services and stay in contact with the important people in your life.  Simply Brilliant.

Besides all that, it folds in on itself like a book, with a sturdy cover so you can stuff it in a backpack or something just like you would a filofax, and it includes a mesh pocket more than big enough for its accessories and room to spare for other things you might want to put in there, such as cell phone and tablet power cables.

Great for emergencies and all day outings--such as fishing or a day at the beach where there is no wall outlet handy.

Got this as a stacksocial deal, and its become my go-to battery backup. I have/had two others: 1) too small of a charge, charges slowly and unreliable. 2) like it a lot and is much smaller size-wise this will likely do for a single phone on a trip. The limefuel is physically larger, but also holds more energy, and is great for travelling with my wife, charging 2 phones at once.
The display is great, rather than the usual 3/5 dot system of a charge, and it has served me well, doing partial phone charges over multiple days makes a great safety net for travels/camping/etc.

Bought this a few months ago when my car battery was dying and it saved my bacon until I could get a replacement battery. The last few days I've been dealing with a blown fuse left in the on position draining the new battery and this thing worked like a champ again. Totally worth it.

I love these as my samsung s3 burns the batter way too quickly bc I am a power user.  Kinda sucks having to take the case off to replace the battery, but when you need power you have 2 new cells in your bag that stay charged for a long time.  Seemed the equivalent to the OEM battery no better no worse.

One of the worst things to happen to a driver besides an accident, a flat tire, or a speeding ticket, is a dead battery. They are time consuming, and usually require more than one car to be involved in taking care of it. Now a days when you try to get help from other motorists, they think your panhandling even before you tell them what you need, and make up their minds to automatically say no before you even explain. (I have been told more than once Sorry, I do not have any money, when all I needed was a jump start.)
Dead batteries happen at the worst of times, and are never fun. My biggest fear is that I will be out in the middle of nowhere, with no phone, and no one close enough to walk to and my cars battery will die. I have had mine die at the drive in movies, sitting in front of the social security office, at home, and so many other places, it is not even funny.
Thankfully my friends at Snan have a solution that is priced right and offers real peace of mind in an otherwise troubling situation.
Snan has a Car Jump Starter 12000mAh 400A Peak Multi-Function Jump Starter Portable Power Bank just perfect for those times when you need it most.
Not only will this device start your car, but it has a powerful emergency flash light and can power for cell phone battery as well. Using it is simple, and the large battery size means I have power when I need it.
As a backup battery for your phone or tablet, it is great. There are two USB plugins perfect for multiple devices. In addition, you have the flash light. It has a strong beam and a fairly large lens size. You can use it to do most anything you need in the dark, including signaling for help should you need it. Beside all of this, there is the jump starting ability that sets this device apart from others.
I have used another car battery jump starter, and loved it. This one is so simple anyone can use it, and I love it. All you need to do is plug in the attachment for the jumper cables, and then connect them to the car. Red always goes to the + and black always goes to the -. If you're not sure which is which, please use the flashlight to see which is which. (One note, do not rely on the cable color connected to the battery. On rare occasions, the previous owner of the car you are driving may use a cable that is not the correct color. Connecting the device the wrong way is not good and could result in injury to you and your battery)
There are no buttons to push and it takes less than 30 seconds to get everything done. Read all of the included instructions prior to your first use, and as a refresher after that. Once you're done, everything fits into the carrying case provided for easy storage.
I find that having a portable car battery charger to be a great addition to your car. You may never have to use it, but should you need it, you can get back on the road in no time as opposed to waiting for hours for another person to come along and help you out.

The micro USB input broke inside my phone and I couldn't charge it any more. This was the perfect solution. I also suggest this set-up for anyone who has problems with battery life. Just take the few minutes to swap batteries and reboot your phone then talk, text and surf all you want.
The charger will charge your OEM battery. It takes longer to charge than to drain.

I have always burned through my iPhone battery quickly. I use my phone for about 16 hours a day and end up recharging it at least once, but usually twice each day. I was leaving town and knew I would be in meetings each day and not have the opportunity to recharge my phone, so I felt it was time to purchase a battery pack. The iTorch was reasonably priced and had good reviews, so I decided to purchase it. The instructions were easy to understand, and the pack wasn't too bulky to carry. When my phone died, I connected the pack then put it in my pants pocket. I used my iPhone cable which allowed me some extra length. The phone comes with a cable to charge the pack but not one to connect it to the phone. This would have been a nice addition, but I had several already, so it didn't concern me. The charge time was quick, and it allowed me to use the phone while it was charging. While I never thought I would have a need for the flashlight or laser, I actually ended up needing one for my presentation during the trip.
I would recommend this product to anyone looking for a charger with some extra features. Just make sure you have a USB iPhone cable as well.

I love this battery case.  In my mind, the S6 is an almost perfect phone however it's Achilles heal is its battery life.  It simply can't get you through a full day of use with anything but the lightest use.  Sure, you can charge it throughout the day but that assumes you have access to an outlet or you're in the car.  You can also connect the phone to an external USB charger but that requires carrying two devices and a cable.  In my opinion the ideal solution is a battery case and this one flat out works.  You can charge both the battery and case through a single connection and when fully charged you simply will not kill this battery in a single day.  In fact, I have an easier time getting two days of use out of this than I do a single day with just the phone.  And the topper of it all?  The price.  This isn't an $80 Mophie case.  It's an inexpensive, very effective solution.  It just flat out works.  Buy it.
