I saw an offer for a 50,000 mAh battery pack at a wholesale price and decided to get one.

I have been using it now for a few days and charging my stuff from it.

Another thing I found was an OTG cable where I could plug the battery into it and power my 1.5 TB external HD. The cable has a USB female and a mUSB female and one mUSB male.

"For why?", you say? Plain and simply because when I have the external HD up and running from the battery I can then plug it into my new Samsung Galaxy Note 8.0.

I ran the HD and was charging the Note 8.0 whilst watching videos for hours trying to deplete the battery to see how long it lasted. Eventually I gave up because I had to go out and the external battery pack still had tons of life in it.

This now gives me a lot of options for travelling and still keeping the amount of accessories I have to carry around with me to a minimum.

I have been burned before by an offer I saw for a 12K battery pack which never lived up to its promise. However I know the vendor and was pretty sure that the offer was kosher this time.

I had to root the Note 8.0 in order to load the app to read the NTFS partition of the HD, but on the other hand, who doesn't root their device?

I don't think an Apple device would give me the option I described above.

Eh, not everyone does root their devices, and some devices you don't even have to root to use USB OTG.

The better solution (at least while you're home) is get a NAS and stream all your media. Once you are on the go, media can be choppy depending on quality of video/connection. But yeah, battery packs are nice to have when you're traveling since most phones don't offer removable batteries these days. I carry a 10,000 mAH battery pack just to recharge my phone if necessary. It's usually enough to recharge my phone 3 full times, and then have a little bit left over.

I'm sorry that I was not clear that I did not mean that I was rooting to use the USB OTG but rather to read the NTFS partition on my external drive.

With regard to the whole removable battery discussion I am pretty agnostic, because at the end of the day you are going to have to charge up the battery.

How large is this battery? Would come in handy for many here in the Toronto area without power because of the ice storm.

I agree with you - except that batteries haven't gotten that much better.

I have designed several large battery banks using lithium ion, lithium polymer and lithium iron phosphate batteries, I have made lithium ion/LiFePo battery packs for two electric vehicles and I fly lithium-polymer powered quadcopter drones daily. I know my battery packs and there is absolutely no way that there is a 50Ah battery in that sized shape. At a guess it's 4000-5000mAh.

I could do the math on what the energy density would have to be to pack a 50Ah battery into something that small, but I can tell you offhand that's it's about 7X better than the best commercial battery available on the market today. Whoever sold it is grossly exaggerating the capacity.

I'm guessing they put an extra 0 there. Maybe it was 5000.0 :D

There's all kinds of overrated battery packs out there.

When I was looking for a phone battery replacement, eBay was full of "high capacity" models (2,200mAh vs the standard 1,500mAh). If you read the reviews, people peeled the stickers off and they were just standard batteries underneath new stickers. :(
Same scam, different day.

Note 8 has a 4600 mAh battery.

A 15000 mAh external battery (see Anker AStro E5) could have charged your Note 8 more than twice

I have a 15000 that I'm quite happy with. I can run my Moto X on it for close to a week. Never tried an external HDD.

The horizontal and vertical are about the same as my phone, but it's twice as thick.
