Last year before ASHA I posted a quick video about why I love the iGo for days when I need my devices to last all day. I used my iGo for ASHA ’11, as well as for trips, long days of work and more. But when I upgraded my phone, it stopped charging my devices. It could keep them from dying but the battery never increased and, once my iGo was dead, my device continues to go dead. So, with ASHA ’12 fast approaching and recently getting a brand new phone that doesn’t allow you to swap out the battery, it was time to get shopping. I knew I needed to get something ‘better’, but I didn’t exactly know what I was looking for – a quick crash course by my dad and my husband got me up to speed!
Two Key Elements:
mAh – A measure of a battery’s total capacity. The higher the number (ex. 600 mAh, 1,500 mAh) the more charge a battery can hold and usually, the longer a battery will last under a certain load. [source]
Amps – A measure of electric current flow. One ampere (amp) will flow when one volt is applied across a resistance of one ohm. [source]
As it turns out, my iGo only puts out ~ half an amp through the USB ports. For newer phones, this is NOT enough to actually charge. Many of the newer phones require at least 1 amp to actually charge. So this year, I knew I wanted to purchase one that had enough amps for my current phone, and hopefully any newer phone I get in the next year or two. I also knew I wanted it to last a LONG time… so I went searching for something with at least 1 amp and a lot of mAh. Here at the best of what I found (click the pictures to go to the Amazon page):
After much consideration, I decided “go big or go home”. So I purchased the New Trent and LOVE it. I took it last weekend to Disneyland with me and it kept my cell and my hubby’s cells charged all day long (and he was taking a LOT of business calls that day!). It’s got a bit of weight to it, about 10 ounces. But if you are going to have that much battery power, you have to be ready for a bit of heft. It really isn’t bad and is compact enough to drop into my purse. The only other downside is it is ANOTHER charging cord to carry around, while the iGo had the plug built in. More for me to lose *smile*
Amazon lists it’s charging power as Apple iPad 2: >120% battery life – Apple iphone 5:> 600% battery life – Smartphones (andriod): >600% battery life. I believe it! This baby is charged up and ready to come along to ASHA ’12!
Will you be bringing an external battery to stay charged up and connected at ASHA? Which one do you like?
