My wife brought a RAVPower 5600mAh External Battery Pack 3 month ago, and she highly recommended me to get a power bank as well. So I decided to get the 10000 mAh power bank from the same supplier based on her recommendation.

First thing I noticed about this product is the packaging is very professional. Most of the unknown branded product I brought from Amazon comes in a white box, The RAVPower power bank comes with nicely designed packaging as well as a proper user manual that doesn't confuse you. The blue LEDs are very bright. The hard black glossy surface is durable, not easy to scratch. But keep in mind that it is also prone to fingerprints easily. Overall, the built quality is really good.

Like many people out there, I never felt the need to have a external power pack. Before this, I had to remind myself to charge my phone every night, which I sometimes forgot and ended up with a flat battery. During the day, I did not want to leave my phone near a power outlet in the office because it is too far away from where I am sitting. Having the power bank on my desk is a perfect solution. Now I can come to my office with a flat battery, charge my phone using the power bank and still keep the phone nearby. Within one full charge of the power bank, I managed to charge my phone (HTC Sensation) 5 times before the battery gets down to only 1 LED. That is 3 days for my HTC sensation to live without the power grid.

One issue I wish to point out is that it takes a rather long time of 8-9 hours to charge up the power bank from empty to full charge. I just leave the power bank charging using one of the power outlet in the office before I leave, and it will be fully charged next morning. Overall, this is a very useful gadget that complements those power hunger smartphones.

I have had two chargers in the past and neither of them charged my new Ipad and my Samsung Tab Plus 7.0. This one, awesomely charges them both in the second USB slots. The first you can charge a Kindle, your phone (mine, an HTC one S), or bluetooth speaker whatever. The piece looks really nice and high quality. Really great tech supplement. As always, the pros and cons:

10,000 mahs!!! This is unheard of at this price point
sleek, good looking, feels good in the hand
on/off switch
charges ipads and tablets of all kinds
charges fast
blue lights allow you to know the power left
lots of plugs for various tech
really great case(velvet black) to hold it all in.

Bit heavy and large for a portable battery pack
Proprietary plug for charging it up (usb for out so that's easy as a lot of you have ipad ipod plugs everywhere in your apt)
Takes a long time to fully charge up. 9hours. (but I concede thats 10,000 mahs you got with you).

All in all, this is well worth what you're paying for, especially if you have a little mini one for emergencies and this one for trips, travels, and times when you need more juice with the ability to charge two phones at once if you want. I have a messenger bag and bicycle daily so i keep it in a side pocket with a plug that leads into the other pocket where i can charge anything i want. I just bought a 99 cent usb plug for my nintendo ds lite so i'll have that too. Good times. Lots of juice!!!!

This battery pack is solidly built and works great. Yes, it does take overnight to charge the thing, however once fully charged up, I was able to charge my iPhone 5 3-5 times (I cannot exactly remember). The great thing about this battery pack is that it has 1 Amp USB outlet as well as a 2 Amp outlet. This makes it easy to charge 2A devices like the iPad a breeze. I have the mention that the charging rate is almost the same or same as a wall outlet. Overall great product, I carried it in my backpack on a recent trip and had no problem getting though airport security. It was especially convenient to have my phone charged while on a hike in wilderness. It is well worth the price. Go get one!

I bought this on another site, but thought I'd share my experience here. I'm a heavy Galaxy S2 and need to carry an extra backup bat just to keep the phone alive. Originally I considered one of those high capacity replacement batteries, but its bulkiness scared me. Then I looked at same size replacements but they can only reach to 2200mAh which doesn't not help me much .

With the Ravpower 10,000mAh battery, I am able to throw it in my backpack or without adding a ton of extra weight thus eliminating the need for car charger or wall outlet. Additionally I can charge my phone and Tablet at the same time with the two usb ports. The unit itself charges very quickly and holds charges for an extremely long time.

The indicator lights are very useful in letting me know when I need a recharge. With so many connectors, it charges not only my phone and ipad, but also my friends iPhone and Kindle as well.

Overall great product, and a must have on the go for those moments when you really need it!

First thing was that it was delivered more promptly than expected, 6 days with free shipping.

When it is fully charged, I have not yet been able to drain it more than half with sustained usage with both a WiFi iPad2 and a Verizon 4G LTE hotspot running from it at the same time. I suspect it would take a couple of days to drain it fully.

With it fully charged and unused for a week, plugging it into a wall charger takes less than 5 minutes to get back to full charge. This indicates to me it can be carried in my case for a long time between charges and still be available for sustained usage.

It takes a long time to charge when 3/4 depleted, of course, so plan for that. That is to be expected when you are charging 10,000mAh.

The smart feature of the circuitry are impressive:
1. It turns off automatically when not charging anything, improving charge life.
2. Charging stops when fully charged, preventing overcharging which would shorten battery life.

I am very satisfied with the RAVPower RP-PB04.
