Monoprice iPhone/iPod Battery Backup: Such a deal
In a previous post about offshore iPhone chargers, a few astute TUAW readers mentioned Monoprice.com as a good source for chargers, connectors, and computer, TV and audio cables. In searching their site, I found a real deal. The Monoprice Backup battery pack is the simplest of devices. When your iPhone or iPod is running low on juice, just plug this battery pack into the 30 pin connector. You can then either keep running with a fairly large dongle hanging off the bottom of your device, or wait and the battery pack will charge your device in 3.5 hours according to Monoprice (or about 2.5 hours according to my tests).
Yes, there are a lot of battery backups that do this, but how many are sold at US$14.50? You read that right, only US$14.50, and for that you get pack with a capacity of 2200 mAh.
For comparison, the capacity of the iPhone battery is 1150 mAh, so this battery should be able to charge your device twice. Due to my ignorance of the vagaries of electricity, mine winds up charging the iPhone about 1.75 times, which isn't bad at all.
This is especially impressive when compared to some of the more elegant competition, like the Mo
True, the Mo
The Monoprice battery backup has a female 30 pin connector at the bottom for charging, which is quite convenient. When charging or discharging the battery backup flashes 4 lights that provide an indication of how much charge is left, similar to the battery displays on MacBooks. When not in use, pressing the right side of the battery display lights up the cell indicators and shows you the remaining capacity.
I really recommend this inexpensive accessory and now keep a couple of them in my computer bag. Monoprice has reasonable shipping prices and a sliding price scale. Buying 2-9 at a time brings the price down to $14.08.

I've had one of these in a more generic chinese casing for about 6 months. You can get them for $10 on eBay. Same 4 blue LEDs, but in a different place. Works great.

monoprice makes very high quality stuff, i outfitted nearly my entire home theater with their speaker and hdmi cables, as well as other various bits and bobs.

I can't get enough of them either. 100ft of terminatedCAT5e so I can wire my game consoles and have much better streaming performance for let's see now.. $12 shipped? I don't really believe in stationary machines using Wi-Fi when they don't need to be movable like a laptop so; yep, count me in. I couldn't touch that amount of cable for under $20 un-terminated at any hardware store. I also lumped in a few RCA couplers for my PSP-TV hook up and a few of the other bajillion goodies on monoprice. I've been mulling an iPhone, and if I do go for it, this will be purchased the day I bring the phone home.

Awesome. Will pick one up next time I buy some cables (monoprice is the best).

I don't suppose this would work with an Otterbox Defender case?

I had an Ottobox case and nothing fit in the iPod connector except the Apple iPod cable. Even the Griffin iPod cable I had in the car had an ever-so-slightly larger plastic enclosure and didn't fit.

BeyondtheTech ...Actually, that's been my experience, too. My wife is getting a 3GS in December and I think we've decided on a Commuter TL case for her.
The Defender case is definitely tough - I've had numerous short drops of my iPhone 3G onto various surfaces - but the docking port area is a major headache. It doesn't work with my Citroën USB box and doesn't work with the little car-charger. So it's a bit frustrating.

It's Mophie, not Morphie, just so you know.

Thanks for the catch. I just redacted the (r)s.

I'm flying 16 hr straight in December. This should ease the pain a bit.

Beware: it's not all good.
I bought two of those battery packs for my 3GS.
They work, sort of: my iPhone will start charging, but after a while will warn that the connected charger is not compatible, after which is stops charging.
It seems highly correlated with what you're doing on your iPhone. If it's idle, the warning may not show up for 30 minutes. If it's, e.g. recording something on the GPS but with the screen disabled (MotionX GPS supports that mode), it usually won't happen that often either.
But try playing a game or anything that requires just a little power and it can happen immediately.
In any case: it's definitely not a perfect solution, even if very cheap...

Same brand? Or similar product?

Same product, bought at monoprice.

The image shows a male connector and not a female. The iPhone/iPod Touch has a female connector...

Ops wrong on my end, sort of. It has both a female and a male connector. The female's for charging in ie a dock and the male is for connection to the iPhone or Touch. The only disadvantage I could see with this thing is that it blocks the headphone-jack while its connected.
johnny said 6:04PM on 10-26-2009
how did you come up with the logic that it blocks the headphone if the iphone charges from the bottom? that really doesnt make any sense looking at the thing.
