External battery for intuition

[star007]

I'd like to have a backup just in case I need one. Any suggestions what company is the best to buy one from?

Thanks in advance....

It is better to have portable charger with you. You can charge it and use it when your phone battery got dead.

How much you can spend to buy the battery?

There're quite a few of choices actually.
If you have a higher budget for this, take a try New trent.
It's inbetween $70-100.
If you have a lower budget, RavPower is a great option.
Theirs is compatible with many devices and brands.

So make a choice yourself.
