Designed for portability, this powerful bar-shaped battery slips easily into your bag for use when you need it on the go. No need to worry about it bouncing around in there, the rugged, high-grade plastic outer shell takes in-bag abuse with ease.

All-in-one charger.
Not just powerful and portable, but also delightfully detailed. Check the remaining power on the four-LED power meter with a click of the power button. We've also included 3 broadly-compatible adapters and 2 cables. Pack the combo in the travel pouch and have all you need for mobile charging.

Very pleased with my purchase. Just wanted to point out it weighs 181g
It charged my iPhone 4S at a rate of twice that of the ipad 3. Suggesting a full charge from 0% in 1 hour for the iPhone and 2 hours for the iPad.

Decided to try this out as I am carrying an ever increasing array of electronic devices for both work and play. I wanted something big enough, but not so big that it added more weight than I need to carry for daily use. This one seemed to be the right size. At 8400mAh it has enough power to charge my nexus 7, wi-drive and phone completely with enough left over for a second full phone charge - I put it to the test on a recent transatlantic trip where it performed extremely well. Charging output is incredibly quick via the 2A port (perfect for the nexus or other tablets requiring a 2A port) and the 1A port works well for my phone. Re-Charging the pack takes 2-3 hours in the UK, but I did find in the US, it took the better part of 6 hours to fully charge via the usb port of a desktop pc - I'm assuming this has to do with the difference in UK-US power supplies. The pack itself weighs about 145g and feels substantial with a good build quality. The pack also seems to hold its charge well - remaining fully charged for 5 days without use, though I suspect that will degrade over time. I did notice the pack and my nexus became quite warm while charging on the return flight from the US (I would also recommend using the nexus charging cable rather than the one that comes with the Anker). Oh yes, and the assortment of adapters is adequate for most devices, though I only use the micro and mini usb's. Overall, quite pleased with the item.

I'm lucky enough to be going to Glastonbury this year and know that my iPhone 5, like all smartphones, won't last anywhere near the five day duration without a few charges. I don't want to be frequenting the orange tent every day, so bought this.

I've tested it and I'm confident this will keep me going throughout the whole festival. I don't feel like I will need to limit my use of the phone and should be able to take photographs and upload stuff as much as I want.

It's a convenient size; not too heavy in my opinion and delivers what it promises. Should serve me well at the festival and any other camping ventures we do this summer - allowing me to look up guitar tabs and chords aplenty using my apps for campfire song requests. Sweet. ;-)

Have you ever stood in a muddy field, soaked to the bone, hunting for a 35mm film pot in a tree?

I have. And after several trips that ended with me swearing and blaspheming at my GPS enabled phone, because the battery had drained just before we could locate that elusive treasure I thought, enough is enough.

I shopped around and this device seemed the most appropriate and economically pleasing.

It certainly does the job, and has solved my battery issues. One charge seems to go on forever, and I haven't experienced it dying on me yet.

The torch has come in handy now and then, but its not that bright, so could probably do with out it.

And now, my Geocaching can go on for much more than the average 3 hours we managed before, which means more mud, more rain, more bickering, fighting over who opens the next one, arguing about who writes in the next log, moaning about being hungry, whinging about being thirsty, sulking about having to wee in a bush... so on, so forth.

The kids see this item as a instrument of torture.

I love it.

It says 8400mah capacity, but actually it can fully recharge my HTC ONE X just 1.5 times, so I'm assuming it has just a 3000-4000mah capacity.

It takes it a while to charge an Ipad, and especially if you use it while charging it, but it does keep it alive and battery slowly increases on the Ipad. If you connect the ipad 3 to the 1Amp USB the IPAD will say that it cannot charge. But if you connect it to the 2 amp - it charges.

Iphone charges fast, and I think I could charge at least 4-5 times.

Build quality is nice. Only the cables seems a bit plastic.

This proudct is great. After an initial full charge, I used it throughout the day charging my phone while using all the things that eat up battery. 3G/GPS etc... Love the fact that it has two USB ports and that one of them outputs at 2A. This means it charges up your phone a lot quicker (if you look at the current rating, its 1.5/2A).

Very handy product. Very useful and charges my iPhone & iPad easily and quickly.
Would give 5 stars but it doesn't have an iPhone 5 adapter- and that is NOT clear in the description and it is a little heavy.

However, it's saved me being without a phone several times and us fantastic for traveling.

Would recommend
