Lumsing 6000mah Portable Power Bank

Lumsing 6000mah Portable Power Bank External battery power Unboxing
The powerbank comes in a fairly well packed in a cardboard box with a little handle and minimal product information on the front of the box.

On the back there is a good list of features:
Size 4.88 x 2.64 x 0.51 inches
capacity 6000mAh
Weight 6.49oz
Input Mirco USB 5V / 1.5A
Output 5V / AA & USB 5V / 2.1A
Service life 500 charge cycles
compatible with all 5volt input required devices.
Security protection design
protection for overcharge
protection for overvoltage
protection for overcurrent
protection for short-circuit
And one of the other product features I thought important to point out:
Made with grade A cells and premium microchips.

The fact that this device lists 4 different protection methods is really important to me. I know it basically just a battery but its a lithium product which im planning on plugging my expensive devices External Battery Pack Backup Charger into and I dont plan on having it explode or overvolt and break my phone or tablet. Having all 4 listed puts my mind at rest somewhat. I also like the fact that they have pointed out that they are using premium productions and a first for any battery pack I've reviewed - they call out the service life! Finally a company that will state how long these things should last. 500 cycles feels like a good bit of usage, I dont tend to use these things a lot and seeing as it can recharge my phone 3 to 4 times I could actually get 2000 phone recharges out of it before it starts to give up. I do a fair amount of travelling and I think it will be a number of years before I use up this product service life.

How to choose a mobile charger travel charger

Happiness is a fully charged battery. Of course, if you travel regularly, you know just how quickly your phone, tablet, mobile hotspot, and other gear can run out of juice.

That's why I consider it essential to pack a portable travel charger, which lets you extend your runtimes without having to seek out an AC outlet (or put extra strain on your laptop by siphoning power from its USB ports).

Ah, but what kind of portable charger should you choose? They come in all shapes in sizes, with price tags to match. You may want something lightweight and inexpensive, but that's no good if it won't charge your most essential devices. So how can you pick the ideal juice-box for your carry-on?

It's all about math. A rechargeable battery's capacity is usually measured in milliamperes (mAh). For example, a Samsung Galaxy S3 comes with a 2,100mAh battery, while the iPhone 5 relies on a 1,440mAh cell.

It stands to reason, then, that any portable charger you buy should have at least as much capacity as your smartphone. That way you can fully recharge it from a fully drained state.

Assuming you'd want to be able to recharge all three devices, you'd need a charger with an 8,000mAh battery.

If you're not sure what size battery your phone, tablet, or other gadget uses, you may be able to find out on the manufacturer's Web site in the tech-specs section.

You can also try what I tried, which is Googling the product name and "battery mAh." So, for example, to learn the capacity of the iPhone 5's battery, I searched for "iPhone 5 battery mAh." Just from previewing the results, I was able to determine the number.

Needless to say, the larger the battery in a mobile charger, the more you'll be able to juice your mobile devices. But larger batteries weigh more and cost more, so you'll have to factor those considerations into your decision.

I should also note that tablets can really throw the equation out of whack, as they tend to have very large batteries. If you thought the Kindle Fire HD's was big, the iPad 3 uses a whopping 11,666mAh cell. Good luck finding a mobile charger that can give that a full charge. (Here are 10 chargers built for tablets.)

Of course, it's just one option out of hundreds. But before you spend money on a portable mobile charger, I urge you to crunch the battery numbers and make sure you buy one that can accommodate your existing mobile gear.
