USB POWER BANK // PORTABLE POWER SUPPLY

If its ok im going for any affordable USB power bank on the market that can charge an iphone or ipad to boot the pi2mB, opinions/suggestion/advice are welcome so I wont resulted a damage pi2mB

I think it was mentioned earlier in this thread, any power bank that can supply around 1A or more should work - if work means

to power the RPI and you don't have much else connected.

Just buy the beefiest one for your application, and try it. It won't damage the RPI, provided you use a decent brand.

If it works, do report back to help others considering the same one.

You can see an example of a typical USB power bank type thing in one of the previous responses (video):

Google has lots of examples of USB battery supplies you could use - e.g. this thread has plenty of links to known working ones, if

you're risk-averse:

Yeah most of the LiPo battery packs are quite capable of 1A. what they tend to lie about more is their capacity or slightly mislead you by saying for example 10AH assuming this is at 5V which is the out put then the total energy stored is 50Wh put in fact they are talking about the battery voltage of 3.7 V nominal so  the energy storage is in fact 37Wh

Both! They first tell you numbers about the 3.7V battery, and THEN lie about ITs capacity. (I got a cheap one, They claim 20Ah, which is "at 3.7V", I measured the battery pack at 6600mAh. It was so cheap that it was still a good deal.).

I have a 20AH which actually must get somewhere close but it's actually its about the size of 3 x200G chocolate bars so is quite large.

Sometimes the claims are just not fundamentally supportable

Well my 20Ah one has 6 18650 cells in it. You can get those with 2900mAh capacity (or even more I haven't checked very carfully), so the other one that was "DIY, bring your own cells" where I put in cells from a reputable western supplier actually has close to 17.4Ah.

I use one of these power banks:

PB-A5200 | RS 5000mAh Lithium Polymer PB-A5200 | RS

It can deliver up to 2.1A and works very well.

Not a bad price considering the retailer  Leon.  To be honest unless the pack is a complete rubbish fraud well beyond the normal bending of the truth they are prone to  any old pack is going to work  find something approaching the capacity you want and hit the buy button.

BTW the 10Ah pack lasted something like 14 hours on my RPi so I'm sure that's good enough for most applications
