Mobile Phone Battery Charger

Post by TC » Tue Aug 12, 2008 1:44 pm

I was wondering if anyone had any experience with the little emergency mobile/cell phone chargers that run of a AA or similar battery like the one in the pic below. Are they decent, will they damage the phone at all? I have seen some that are so ridiculously cheap that I couldn't help wondering if they were going to fry the phone due to shody construction.

If they are any good, I'd appreciate suggestions on any particular brand that is good to buy. Also, if anyone knows of any other small sized charger that can plug into a mini-USB port, I'd love to hear about it. I've got a wind up charger, but I'd rather have something that is smaller and doesn't require me to wind a handle at just the right speed for an hour!

Here's a pic to show the sort of thing I am talking about:

I gave the same unit to my son, with extra batteries, to at least partially recharge his cell phone when he went to a 3 day, camp-out, rock concert. It did not work for him, perhaps because he didn't use it until the phone's battery was DEAD. This prompted me to switch to the twin lithium AA battery Charge2Go units. I haven't yet tested the new units.

I have the Energizer version and with 2 lithium batteries it will recharge my Motorola Razr quickly or better yet, it will allow me to complete a phone call if my battery gets low. 2 AA batteries (lithium or alkaline) equal 1 charge so it is not cheap but for critical calls it is great.

Personally I have 3 batteries for my phone (I use about 2,000 minutes per month, so yes I am a blabbermouth). I have 2 regular batteries and one high capacity batteries. It works better to just slip a new battery in to replace the discharged battery. A new battery is about the same price as these gizmos and is reusable. However that does not work if you are in the middle of a conference call, hence the need for the battery gizmo.

Personally I recommend a couple of spare batteries first then buy the Energizer unit. The other thing I do is use the USB port on my laptop to steal power from it to charge the phone. This assumes you have both a laptop and power for the laptop obviously.

Amen. It took some fast talking to get my wife to go for a phone with a USB connector this time around, but it has already come in handy a few times.

I also have the Energizer charger you mentioned. It was on clearance at the hardware store for $15. It may be worth noting that the phone (at least mine but I expect the same with most) can run off this with the phone battery removed completely. This would be handy if the battery is lost or damaged and cannot be connected.
