Portable External Battery Charger for an iPhone 4

I am looking for a portable external battery charger for my upcoming trip. But i don't know what brand to buy, anyone recommend the best external battery to me. By the way, i also want to know what is the distinction between Verizon iPhone and iPhone 4? Are they made in Apple? Thanks in adv.

In my opinion ,it is not that important which brand you choose .The most important is the quality of the product

Discharge current capacity and safety measures are the main things to be considered about chargers. I got a quality "icharger(icharger)":http://www.mrpositive.co.nz/brands/iCharger.html at lower price. Never had any issue with it.

That's the best comment Ive seen today

Some one is thinking along the same route as I am

I must congratulate you on that comment

Quality is very important " not just cheap" but quality , even if you do pay slightly more for this A it makes you work for something an appreciate whats you've worked for B : It provides you with an aim in life To be the best or produce something that is of reasonable standard Not throw away and hence why the world is in the depression it is Reason everyone wants cheap and now of course we have a major problem That,s why I build my own

I'm also sick of the quality that's being delivered as well and its cheap society and its cheap standards together with cheap labor

It likens us to now more than slave drivers hell bent on making as much profit as possible with little importance on life

An extremely cheap intolerant greedy society that is now ever present in modern day life , with no appreciation for craftsmen ship of technical achievement but rather a very cheap out look on life regarding life equally as cheap and dirty hence the filthy dirty business tactics of today No morals and equally cheap attitudes

Ive had to comment on this because you are just so right about this

Thank you at last someone who is not ashamed to speak his / her mind I thought it would never happen

Let me suggest you ChargeMax a 20000mAh external dual charge battery.
It actually uses high quality battery instead of the cheap ones out there and it has Discharge current capacity and other safety measures which is really important.
I have tried several external battery charger and this is by far the best.
You can buy it through this website and it includes free shipping within US.
