I have been using it for a month now, and there haven't been any issues. It charges fine and the time usage is also decent. For the cheap price and convenience, I would definitely purchase this laptop battery again.

It works well, blocks out most environment noise & holds a good charge.  But the real reason I am truly impressed is that my husband left his in his pocket.  He ran it through the washing machine and dryer. He recharged it & it works just fine and has for at least a month.  Amazing - I thought for sure he fried it.

I received this as a free review sample. I subtracted a star because while this is a decent battery, it is not best in its class. For one thing the 6600mAh capacity in a 6.1 ounce form factor is neither high capacity when 10000+mAh batteries are now common, nor light at over a third of a pound. Another reason why I subtracted the star is the ports max out at 2 Amps, whereas there are batteries out that go all the way to 2.4. Again, this is still a decent battery, but I did want to mention why I rated it the way that I did.

It is fairly fast, holding its own against wall chargers when I tested it with two Samsung devices (a Note 4 phone and a Tab Pro 12.2 tablet), and an iPhone 5s and iPad Air 2. Note that the two ports are marked Rapid. Do not confuse that with Qualcomm's Quick Charge because I tested my QC-compliant Note 4 and it did not flip into that mode.  Of course, there are no claims in the specs that this goes into QC mode, but the 'Rapid' labels may confuse some folks who own QC-compliant devices (and Go Puck does have a model that is QC compliant.)

This battery charges at a full 2 Amps, so if you have a 2 (or higher) Amp wall charger you can charge it from nearly empty to full in about 3.5 hours. Plus it does not get overly hot during charging or discharging, which indicates to me that it is well designed and constructed from quality parts.

Do note that all batteries made from this technology, including competing brands, are about 70% efficient. While this one will store a full 6600mAh, losses from heat and the transfer process, and the charging cable itself will reduce the usable capacity that you transfer to your phone or tablet to approximately 4620mAh. That is still a lot of backup - more than enough to keep my Tab Pro 12.2 tablet running four more hours over the eight hours I normally get from it, and double the time I get from my Note 4 phone (plus some!)

Bottom line: this is a high quality battery that performs well. It is designed to be wearable, which is not one of my requirements. It is a little on the large and heavy side for a 6600mAh battery, and at that capacity is lower than most business class batteries currently on the market. If you have special mounting needs this is probably your best bet. If you need a general purpose battery you may want to continue comparison shopping.

Battery life isn't the greatest but as long as there's an accessible outlet nearby, doesn't really bother me. Overall, works really well, fast downloads & processor

the 9cell extended battery did a good performance.
you won't worry about losing power when you are on the go.

fit is very good & the battery has been running without overheating, which can cause size distortion.  It is also cycling/charging very consistently to a high % of power.  Am looking forward to this behavior continuing.

This is not my first charger. I must say I like this one so far and it has met my expectations. I know these things tend to loose the ability to hold a charge as the years progress, but with that in mind, this baby will get you through many charges of your cell or tablet with ease and convenience.

Battery is great and you get a good amount of play time per charge sometimes it might not feel like it if you lose track of time playing games like I do you be thinking it didn't charge nothing but don't realize you spent your whole day off playing lol also charges quick and you can play while charging overall a good buy

For the price it's a very good product. It's small & light & in a pinch it's good for 1 full charge.

Hey, it worked for me. Its cheap and the battery has worked over the course of the year. It doesn't retain charge for too long, but solid nonetheless.

It makes a good backup battery but discharges quick because it's charging the phone and running the phone even with it being 3200mAh. I ended up getting something else and gave it to a friend.

I use it jogging and really enjoy its small size and extremely good reception for listening to the radio.  Dowloading songs into it was easy and it has held up to abuse.  It also keeps a decent charge (I use it 4 times a week for 30 minute jogs and usually I have to charge it every 3 weeks or so).

it shows condition of each batt in the unit which is helpful and it charges powers my phone which is another reason I got this charger.  It only had 2 flaws, the charger wire that came with it didn't fit very well (I replaced it with another and it fit fine)  the multi cord it came with for all types of phones the Iphone plug didn't work (I replaced it with another and it worked fine) tho the android plug worked fine, but the unit itself is doing what I bought it to do.  One thing I really like about it as a spare power source is I can insert charged batteries and keep using it away from power sources

I wanted to have this around in case of an emergency, I have car chargers, home chargers, I got this as a back up. It holds a good charge and I tested it on my S5, charged quickly. Not sure if I'll ever need it, but its a good feeling to know I can always charge my phone, and I might go camping & need it there.. I now have GoPro's and I like having this back up power.

It works as its supposed to - Easy to use - holds charge long enough, and takes a few good hours to get recharged
