I am planning to get a handy size phone battery charger for my daughter. She's using iPhone5. I wish it won't be more than $25 and can be easily carried. Give me some ideas, thank you.

Go to your Apple vendor...

ebay or amazon is where I would look

google Iphone chargers for a idea of https://www.google.com/search?q=iph...e&espv=210&es_sm=93&ie=UTF-8

this one looks intersting

Have one of these, works great with my old Android phone and new 5S. There are also bigger ones available now.

Heard that Mophie is a great one, but the price is obvious too much for me. Think I'll try on this one, RavPower 2600mAh, https://www.amazon.com/RAVPower-Fla...UTF8&qid=1383127109&sr=8-1&keywords=2600

I have the powergen one that ampleworks posted and it works well.

Got this one from RavPower. Luster gold~~ I wish I had an iPhone 5S gold. https://www.amazon.com/RAVPower-Flashlight-Lightning-Sensation-Thunderbolt/dp/B00APFQ5VS
