DLO Jumpstart Attachable Battery Pack for iPhone and iPod Review


dlo-jumpstart-review-1I don’t have an iPhone, just an iPod Touch, so having a battery die at an inconvenient time isn’t devastating for me.  I still have my phone if I need to make a call, so I can feel free to listen to music, use apps, connect to the internet if I’m near WiFi, even play Bejeweled2 as long as I like.  However, I still don’t want my battery to die when I’m out, because I LIKE to play Bejeweled2.  Enter  the DLO Jumpstart, an attachable battery pack  that is designed to ensure I have enough power to play any game I want until I get back to a power cable.  When Julie offered it to me for review, I was happy to give it a try.

The Jumpstart is a battery pack that works with the iPhone 3G and 3GS, the Touch, and several other iPods.   (To make this easier to read, I’m just going to use “Touch” when I talk about the Apple device.  That’s what I tried the Jumpstart with, and it’s easier than trying constantly to list every device.)   The Jumpstart is a black rectangle with a rubbery skin.  It is about 4.75 X 1.75 X 0.5 inches, and it supplies 1200 mAh to double your battery life.  The Jumpstart has a short, stiff, J-shaped cable that plugs into the dock connector, and it attaches to the back of your device with twelve little suction cups.  You can leave the Jumpstart connected to your Touch so that it continually keeps your battery “topped off”.  If you have a case you prefer to keep your Touch in, you can throw the Jumpstart in your gear bag and plug it in to your device only when you need to recharge your battery on the go.


The Jumpstart attached to the back of an iPod Touch 2nd gen.

The biggest problem I had with the Jumpstart was the lack of documentation.  There was no insert in the box – just the Jumpstart and a USB to mini-USB cable.  I looked at the DLO web site and found a manual, but it turned out to be nothing but two line drawings that didn’t make much clear except how to plug it onto my Touch.   I wasn’t sure if I could charge the Jumpstart alone or if it had to be attached to my Touch to charge.  I decided I’d just go by intuition, so I plugged the Jumpstart into my Touch, pushed the suction cups against the back until they stuck, then I flipped open a cover on the upper left corner of the Jumpstart to uncover the mini-USB port.  I connected the Jumpstart/Touch combination to my computer using the included cable.  A red status light on the top of the Jumpstart indicated that something was happening.  Since I had no idea how much charge the Jumpstart may ship with, I decided I’d just leave it plugged in for a few hours while I did other things on the computer.  As soon as I plugged in the cable to my computer, iTunes started up and synched up my Touch.  Being able to synch without having to remove the Jumpstart will work well for those people who elect to leave it attached all the time.

To begin the test, I removed the Jumpstart and used my iPod until I ran the battery completely down.  I used it until the iPod just turned itself off and wouldn’t start.  I attached the Jumpstart, and I almost immediately got the charging screen on my Touch.  After about 2.5 hours, my Touch was completely charged.  My battery monitor app showed 100%.  I didn’t use it while it was charging, because I wanted to see if the Jumpstart was capable of completely recharging my battery.  In later tests, I found that I could use the iPod while it was charging.


The Jumpstart recharging the Touch battery

I assumed that after completely recharging a flat battery, the Jumpstart would be ready for a charge itself.  Since I still hadn’t found any good instructions, I just left the Jumpstart attached to my now-charged Touch, plugged everything up to my computer, and waited to see how long it took to charge.  In about 2.5-2.75 hours, iTunes showed that my iPod was completely charged, so I assumed the Jumpstart was as well.

There is a status light hidden at the top of the Jumpstart under the black rubber coating.  There is also a hidden button on the back near the status light.  Locate the button by looking or feeling for a dimple in the surface.  Pushing that button turns on LEDs that seem to indicate charging status.  While charging the Jumpstart/Touch, a steady red light was on.  The red light eventually changed to blue, to apparently indicate charging was complete.  Nothing I saw with the status lights seems to match the confusing “manual” diagrams, but then I wasn’t sure what the line drawing was trying to tell me anyway.

I have a Zagg invisibleSHIELD skin on my Touch, and the suction cups didn’t stick very well.  I didn’t remove the Zagg to see if the suction cups stuck better to the metal.  Then again, the lack of suction could have been due to the lint the cups picked up in my bag.  In any event, it stuck well enough while I was recharging on the go.  It probably would become more of a problem if I decided to leave the Jumpstart connected all the time.

The Jumpstart worked great to completely recharge the drained battery in my Touch.  I like the convenience of having it in my purse for a quick recharge when I’m away from home.  I do wish the documentation was better.  It seemed to be rather intuitive to use, but I’d like to be sure!  And remember, it doesn’t just work for the iPod Touch.  It also works for iPhones and iPods that use the dock connector.  See the DLO site for a complete list of supported Apple devices.

    the jumstart works well for the IPOD Touch 3rd Gen although on the package the 3rd Gen IPOD is not included in the compatability list. A few things i found out that might help someone looking to purchase this:

    1. you do not need to have it plugged into your ipod to charge the jumpstart. just plug it into your computer using the supplied USB cable and a small LED on the jumpstart will illuminate red means it’s charging and blue means it’s charged.
    2. to check if the jumpstart is charged or not simply press the small circular indentation on the back of the jumpstart and the LED will either light up red or blue.
    3. when your ipod battery is low simply connect a charged jumpstart and continue to use, the jumstart will charge your ipod as u continue to use your apps or listen to music it completely charged my ipod in around 2hrs.

    hope this helps.

    & Rich!
    Thanks for all the useful information about the jumpstart. I was scratching my head trying to figure out what was going on with it!

    I just bought this last night, and I was also disappointed by the lack of documentation. I am puzzled and vaguely amused that there seems to be a button on the back that’s only function is to activate the LED light.

    I had a 3GS and it worked great for me. The suction cups, however, didn’t work very well. I took a razor blade and carefully cut them off without cutting a hole through the rubber back. I then went to WalMart and bought some 3M large velcro strips, which were a little more than an inch wide. I had to superglue the velcro to the rubber, since the adhesive wasn’t enough to keep it on the battery pack. I chose to put the soft fuzzy side of the velcro on the phone since I didn’t intend to keep the JumpStart on it at all times.
    I like to keep it charging in the truck and now whenever my phone gets low, I put it on there long enough to get above 90% charged and then return it back to my truck. Also, if I have a friend around with a phone that is dying, I can pass it off to him.
    I love this device, I just wish Apple had offered an optional larger battery from the factory!

    I like it because it is the only external battery I have found that I can put on without removing my case. The others require that the battery be flush up against the iphone, but this allows me to plug it in while the case is on. 🙂 The suction cups aren’t great, but they are good enough.
