Comes up £24.99 online from Hughes (on Tesco Direct). So if available in store then great deal.

I've got 2 of these and can recommend then, little bulky but can get two full charges for my galaxy note 4, I bought the second one as the first was so good and I paid £24 for the last one a few weeks ago :confused:

That's not great if you can only get two charges for your note 4. The capacity of this power bank is greater than that

The Note 4 has a 3220 mAh battery so you should get 3 full charges really, that suggests the listed mAh of 10,400 is a bit of a fib.

Some here don't understand energy transfer. Also likely that they are still using the Note 4 whilst it is charging so some will be used to power it during charging time. As for capacity...
"It’s important to note that a power bank will not deliver its full advertised capacity to your device – some of this energy is lost through heat generated and voltage conversion. If a power bank manufacturer doesn’t expressly state otherwise, expect to achieve around 70 percent efficiency. A 10000mAh power bank might therefore deliver 7000mAh of power. Some of the best power banks offer around 90 percent efficiency."
I'm glad you said it because it needed posting! Not only that, but people seem to forget it has a 3.7V battery, converts to 5V for USB and then is converted again by the phone back to 4.2V (the Li-ion charge voltage); all this conversion doesn't come for free!
OP, how many were left in Tesco in-store at Bursledon when you saw them? Would like one, especially as it's a convenient shape but it's a bit out of my way.
Thanks!

If your phone is drawing 1 amp
then the battery is supplying
5/3.7 amps
Thats the cost of boosting 3.7 to 5volts
