Customer Ratings & Reviews

I have been using this device for over a month now and I love it. I can get at least 1 full and a 60% out of it before I have to charge it again (which takes several hours) and I don't plug my phone to it until it gets to about 5% or lower. I gave 4 stars because it is very bulky and really cant fit in my pocket and because it literally takes SEVERAL hours to charge (5+ hours). Other than that I love it!!!

I just loved this. It is small yet can charge several items to full charge before needing to charge the actual cherger. GREAT!!

I hold enough power for 4 hours of charge and charges with any usb outlet.

Quality battery pack that is small and portable but powerful enough.

I love this battery! I get 2 full charges out of it for my Galaxy S6, and it was so inexpensive. I take it everywhere just in case!

really liked the price, think it was $10 on sale. fast charging.

We bought this to take with us on trip to Disney. It worked great to get 3 phones through the day. You can't beat it for the price.

This charger is great for the price. It holds twice as much capacity then other chargers that is more expensive then this one.

When you're on the run, this is the charger you want. Compact & easy to use.

I purchased these battery packs to check them out and for inexpensive gifts; they are great. We've used two of them during our travels and they hold up really well. They charge quickly and they charge our phones very well. I can fit one in my purse while charging my phone. These are such a great buy and inexpensive.

Charges phone fast and it is easy to keep up with. Can charge on the go

Awesome product very durable and outstanding highly recommended.

Perfect for a quick charge, use it on my iPhone 6 plus and can get 2-3 charges from this for the price it was a steal

I coach youth sports and sometimes i'm at the field all day long with no place to charge my phone. it's important i have it for parents/players to keep in touch with me, follow weather reports, tournament updates etc, or God forbid, someone get seriously injured and emergency services need be called. I bought a pair of these due to a promo and I don't regret it at all. i've been able to charge my phone 3-5 times based off one charge from these.

I bought this for our days at the amusement parks. Charges two phones (1at a time) before having to charge the portable battery again. it allows us to take for pictures and videos without the phones dying. I've had other smaller ones that I paid more for! I will definitely buy these again in the future.

its easy to use. very handy. durable. can charge your devices fast

Works good to charge her phone small and fits in her backpack.

I have been in the business of dealing with Lithium batteries as my day job for a couple of years, so let me start out with saying that there are NO perfect batteries, they will all lose the ability to retain their full charge over a limited number of charge/discharge cycles, and there is always some potential for inconsistent results in manufacturing regardless of QA... SPECS/USABILITY: this is a fairly solid little battery, with a surprisingly accurate capacity. Many manufacturers give bloated specs that only apply at certain voltages, or certain loads. This will, surprisingly, get my wife's iPhone 6S up to full twice from around the 15% mark... Not quite two full charges, but close enough to 5200 mAh for the price. It will discharge at 5V 2Amps, which is a total of 10W - This is the maximum charge that many current mobile devices can take. While many phones are either limited to, or only include chargers for 1A, tablets like the iPad will draw just above 2A at peak, and this will mostly do that. Not bad for a tenner. The only odd limitation is that you can only charge at 1A, which means that it will potentially take twice as long to charge it, as it does to discharge it. This is likely due to the battery management system, which may not be robust enough (or the battery itself may not be robust enough) to accept a higher current charge. Not a big deal, but don't expect it to fill quickly; It'll take a few hours. Many people have asked if this is Li-Ion, and the easy answer is yes. However, it is not clear from packaging, customer support answers, or the unit itself what exactly the battery is. However, based on the charge limitations, and price, I would guess that it is Li-Polymer, which is something akin to what your phone or gaming devices use. It has reasonable life (number of charge cycles), is quite light, and is relatively cheap, but is also the type of battery that is most likely to have heat or fire issues if mistreated. Almost all of the horror stories you hear about bad Lithium batteries are from Li-Poly, but usually the very, very rare instance where QA wasn't good enough. There are more stable options (LiFePo - Lithium Iron Phosphate, for one), but they're usually heavier, bulkier, require more intense battery management circuitry, and because of all of the above, and the manufacturing itself, are considerably pricier. So, Li-Poly it is, most likely, which puts it on par with most cell phone batteries. BUILD QUALITY/USAGE EXPERIENCE: A little chunky for what it is, and you have to be careful for the USB ports - They ALL need to be handled gently, both on the type A ports for charging your devices, and ESPECIALLY on the type C micro port for charging the pack itself. It is very loosely soldered on, and can easily be broken (which is not readily fixable - I bought three, and broke one on accident, and it was not something that your average Joe would likely be able to fix). However, the rest of the exterior is very sturdy, and can easily be toted in a purse, backpack, or pocket. Great for camping, hiking, hunting Pokemon, or even just having at work for when your phone, or a coworker's phone is about to die. The material feels good in hand, but despite the cool looking design for the cable management, those wings do not bend; Only thin cables will be able to fit through there for easy storage. If you have thicker, braided cables, don't plan on using those. But it is simple to use - You simply plug in your device, and it will automatically start charging at your device's upper limit, or the battery's upper discharge limit, whichever is lower. If that does not happen, you hit the single power button, and it will start, as well as display your current charge status, which is surprisingly accurate. TL;DR / SUMMARY: This is a great little battery for the price, with a few nice considerations in the casing, like the cable management. The battery capacity is reasonable, and it is capable of charging high power devices like tablets without problems. It is likely a Li-Poly battery, which isn't fantastic, but is far from horrible if made well, based on my years of experience - Should be comparable to your mobile phone battery in composition, and power density, which is why you should get around two full phone charges, depending on your phone. The few negatives are that it is a bit on the bulky side for what it provides, the cable management system is limited to the thinnest cables, and it takes twice as long to charge it as it does for it to charge most devices. Overall, recommended highly for the price, and performance. Shouldn't have a problem, so long as you are careful with the ports, and don't try to force it to charge/discharge too quickly. Cheers!

Great charger: I bring this to sportsball bars and the like when I'm watching a game. Can take my phone from empty to full even while running wi-fi, etc. There's even a couple bars left over for friend's phones. Great purchase. Does fit in a pocket, although obviously not the tiny change pocket. it goes with me most times I think I'll be out more than an hour or two.

Easy to use. Great charge! Took it to universal studios and charged my iPhone and my wife's iPhone both to 100%
