Nope, didn't happen, due to those pesky 'laws of physics'.

It's £4 odd for delivery if a non prime member, what's up with that?

I have one of these or a 12000 mAh one. It's a bit of a beast, but great for in the car or taking on holiday, or out and about in a bag . I wouldn't attempt to put it in my pocket though! Takes a while to charge, but holds charge well (several weeks) and charges devices quickly. The option to charge 3 devices at once is great. I also have a xiaomi mi power (or whatever it is). That's a "nicer" device and is just about pocketable. IMHO this is a great price for this device. They are just so handy!

Expire

price is £19.99? am I missing something or has price gone up since listed?

Let's assume your 2% is correct (it's clearly not), then over 12 months that's 24%. A quarter is gone. That's not 'full charge' or '90%', which is what has been claimed. As I said, the reality is that you will be lucky to have half of it left after a year. Absolute bargain-basement cells (no-name chinese tat) will be 1-2% left.

Here's the good review on youtube of it if anyone's interested. He gets a bit over 13,000mah from it in direct translation terms, after power conversions, which is about right for the stated capacity. Each battery is 2600mah so this would be excellent even if pulling the batteries for other uses. This all assumes it's the same product still being sold of course.

Bought same one 4 months ago for less than a pound more. Appears to hold charge well for weeks and capacity rating is about correct. Big and heavy but a useful power pack if you need such a thing.

Sorry but you are assuming these are poor quality cells yes they may be do you actually own this battery ?
Good quality cells are now around 2% per month not just the mega expensive one,s
Yes protection circuits did use around 3% per month but things have changed its called progress
Its 2016 not 1975 by the way
Yes there is some rubbish cells from china still but there are some pretty good ones as well

Is the voucher code still working?

These are not 'good lithium ion cells', they are cheap mass-produced junk (hence the low price). 'good' lithium ion cells cost hundreds of pounds and are only used for top-end equipment (movie cameras, emergency, electric vehicles). Even they will not have 90% left at the end of a year, as they will lose 2% per month. Normal powder-rammed-in-plastic-bag lithium batteries such as the ones in this deal will discarge at 4% per month at least, as well as 5% in the first 24 hours. So after a year, that's a 53% loss (+12% if it has a safety circuit).

So NO, you will not have 90% after a year. Sorry.

I think the poster is actually referring to the stupid 2-tier pricing policy Amazon operate now, whereby everyone who gives them a £79 bung every year gets a different set of prices compared to Amazon's non-preferred customers (i.e. the majority who see through them).

If you add the Free USB stick this brings the total for powerbank and USB to over £20, so postage is Free (but you only pay the £12.99 for the Powerbank after you add the voucher code)

Think your been bit hard as good lithium ion cells still be at 90% after year stored at about 15c
due to those pesky 'laws of physics they have low self-discharge
So would still show full charge

Mine arrived this evening. Seems good but heavy. Charging it now

8gb USB no more in stock

Daft question; I have checked the Amazon 1 star reviews and most say that it only delivers about 12,000. Has anyone that has it checked? Also, the customer service is reported as terrible if anything goes wrong.

I was going to buy to replace my daughter's "mislaid" Xiaomi 10,000 but I think that I will just replace with the same having seen these reviews.

Can you charge the charger and then use it to charge your phone at the same time?

Something like a USB passthrough?

Just a word of warning.
You need to be careful if flying with these power packs. I recently had one confiscated at Bangkok airport because it exceeded 20000mah. I tried arguing that I had flown everywhere with it but they took it away and through it in to a clear plastic rubbish bag. There were quite a few other power banks in there already.
It was a nice piece of kit as well.

Think you're getting a bit confused between "Restricted" and "Prohibited"

The link refers to international posting. The info is here: http://www.royalmail.com/business/help/sending/restricted-goods

going NYC in a few weeks, this will come in handy. Nice on OP.

This is the best charger I have, good find Mr OP

power banks have been reclassified as restricted goods and can't be sent by individuals by RM http://tamebay.com/2016/01/portable-battery-packs-banned-by-royal-mail.html

You could possibly argue this is a torch, but it's a bit of a stretch.

E: hemes isn't that clear either.. they have "batteries" listed as prohibited, but not on the "full list of prohibited items".

is there a postal service that allows an individual to send these?? (they're prohibited from RM AFAICT)

Love mine, they really are the pups nuts especially at this price. good find.

hot. ordered

it takes ages to charge in full. I use a 2a charger.

Both 8OZ5537S and NWZ6KZX8 come up with "The promotional code you entered cannot be applied to your purchase" for me.

Thanks for the reply. Ordered!

I need one of these for a trip to Thailand. This wouldn't be too heavy in a bum bag would it?

Too big. Just ordered the Anker E1 instead. I do appreciate the power of this is a lot more than the Anker which is 5200 mAh but personally I wouldn't prefer carrying around a power bank of that size.

No luck with thh iphone case :disappointed: no worries still a scorcher!

No luck with the freebie codes?

It's an absolute beast. Red-hot at this price

size and weight
Product Dimensions: 16 x 8 x 2.3 cm ; 463 g

I am tempted to order it just to strip the lithium cells out and replace my laptops aging battery

just ordered, thanks

OK thanks for explaining it for me guys.

All1

I assume this isn't Fast Charge 2.0 compatible?

I've just ordered one and had the option for free delivery ??

It was quite happily going to send one (and the free Santa 8Gb USB) for £12.99 - I added the case on and have the whole lot being delivered for £19.28 - bargain !!

Can anyone explain to me what the 3 USB ports are for, I know the OP says "2.4A for iPad, 2A for Samsung phones, 1A for iPhone)" Having no Apple gear i used the "iPhone" socket to charge my normal 3G phone and my LG G3 but what about charging other tablet or even torches etc.

I plan on going off grid for about a month this year so bought another 3

I'm voting this cold because of the stupid non prime price

Brilliant charger. Use mine to charge my Iphone 6 and can easily get 5x charges from it. Brilliant at this price.

I'm not sure that's true anymore. I bought a cable off of Amazon a couple of weeks ago for £2, and it both charges fast AND carries data.

Anyway, it's charging the actual battery pack that's slow. I've found charging my phones with this is really speedy!

For those saying it takes ages to charge your device, this may be due to USB charging limitations on your actual device. My Nexus 5 is limited to 500mah over USB so connecting to a 500mah or 2A or 4A port with a standard cable makes no difference. You can however get a "Dumb" USB cable which has no data capabilities and acts like an AC charger rather than a USB charger, which bypasses such restrictions. An example of such a cable can be found in the link below, I'm sure others are available too. The important part is they carry no data therefore the device thinks it's AC rather than USB.

Food for thought!

Good deal. Works fine. Useful extra sockets.

Fine for bag, not for pocket.
About the weight of 3/4 bag of sugar

Nice. Now where to put my old external batteries - do they just go in the battery skip?

Great deal I have several of them - great for camping or when you are travelling and you have several devices to keep charged, also purchased many for friends, they loved it. My brother went to India and said it was so useful.

Cracking deal. I have two of these and they work really well.

I've got one of these, left it in my draw for nearly a year, took it out only last week and it was still holding full charge!
Good piece of kit IMO

You need to charge it overnight but once charged you get 3-4 full charges of your phone out of it.

Only downside is that it is heavy

Great bit of kit - price wise it's often at around this price point. I paid £12.40 late last year on Amazon, so if you miss this one it will be back.

I bought one of these last year. Though it takes ages to get charged (like most battery packs) it charges my devices really fast. Recommended!

Ordered two of these the last time, brilliant portable battery, bit bulky but charges devices a fair amount of times? Heat

Have this one and I really recommend it. It´s very fast charging and lasts forever.
Very heavy though, but a bargain at £12.99.

Had one of these for ages, it's great.

cheapest it's been. will buddy up with my older anker. thanks
