Extended / Travel Battery Idea

[webdude12]

I have an extended / travel battery idea.

Imagine this:

A small box about the footprint of our Evo. This box holds 2 of the regular batteries (think side by side flat). It has a normal USB Port on it and a micro USB Port. And maybe a few indicator LEDs. We can then hook this small box to a USB Charger, a Laptop, etc to charge the batteries inside.

Then when our Evo needs more juice, we have one of two options. Either pull out one of the batteries from this small box, or plug via USB cable into this box to charge the battery in our phone from the two batteries on board.

Does anyone know of something like this? Is this something people would be interested in buying if could be purchased cheap enough... Maybe this is something when can petition Seidio to make?

Sounds good,but also sounds like you would end up paying almost/around $100.00 don't think many people would like that.I would buy it though.

Well the idea is to sell the box without the batteries directly. I personally have 3 extra batteries because I had a TouchPro 2 before, and acquired a 3rd extra battery recently.

But because we are using the "stock" batteries in the thing, it can be used with either 1 or 2 batteries. I would think the device could be manufactured for less than $10, and I personally would pay upto $20-$25 for the box without any batteries.

I did something similiar to this. I combined the charger from this:

2x 1500mAh battery + dock charger for Sprint HTC Evo 4G - eBay (item 250641711190 end time Sep-27-10 01:08:58 PDT)

And this:

Minty Boost! - USB charger for your gadgets

Together to make a device similiar to your idea.

Review: Splash Intense 5400mAh external battery pack for HTC EVO 4G



and theres few more

Amazon.com: New Trent ultra high IMP500 5000 mAh External Battery Pack for 3G iPad, iPhone 4 4G, iPhone 3G 3GS, iPod Touch (1G 2G 3G), Motorola Droid , HTC Android Phones, Blackberry (curve, bold, tour, storm): Gateway



maybe just get extended battery instead ?

I had one of these (not the exact model but same concept) with my Mogul and TP2 and it worked very well. I used Sanyo eneloop rechargeable batteries because they have a long shelf life without self-discharge. (1.2vx4=4.8v), and it provided about 2800mAh, or enough to almost fully charge the battery twice.

I paid about $10 for the battery box, and it more than paid for itself.
