HACKING THE NOKIA POWER ADAPTER CABLE

As my demand for internet connectivity increases, equipment that connects to the internet needs to keep up too. If and when my iPad 2 battery runs low I have the i.Sound 8000 mAh Power Max. When my Nokia E71-cum-Personal-Hotspot runs low, I have this single “AA” battery powered inverter. The trouble with third-party connectors that they’re very often unreliable. By that, I refer to  to the 2mm power connector contact isn’t as secure as the original Nokia part notably (in this example) the CA-44 power adapter pictured below. I’m not big on carrying additional items unnecessarily and seeing how the i.Sound power pack has extra USB ports (see third picture) and enough juice to also charge the E71 while it’s charging the iPad—perfect! This modification is unnecessary for owners of Nokia E72 — the USB data port is capable of charging the phone and Nokia includes a short cable for this purpose (too short in my opinion for practice use especially when you need to answer a call or send a text while the short cable is in use).

This is an original Nokia CA-44 power adapter cable with the female pin spliced open.

Nokia has a part number for the cable I want — Nokia Charger via USB CA 100 — short, neat and most of all, elegant. Trouble is this item is highly unpopular and most people I’d imagine have no need for such set-up other than the factory AC and maybe a car adapter. Another thing, the CA 100 is such an old part number I couldn’t locate a store in my town but I found a similar functioning cable that has an additional cable for data transfer. The part I wanted is the power charging piece and unfortunately but not unexpected the connection isn’t very secure and as a result intermittently disrupts charging due to poor contact. Here’s where my D-I-Y light bulb in my head went off difference this time, I got my dad to help as he’s much better at handling delicate electrical items than I have the patience or skills for. Now, is it a coincidence that I also enjoy Grey’s Anatomy, Private Practice, House because I happen to like cutting things up? Likely not considering what we like and do are probably a result of years of visual influence.

A China made two-in-one USB power and data cable spliced at the Y junction to reveal the rather the soldered wires underneath.

Tada! The finished product, a fusion between original Nokia  CA-44 2mm adapter plug end and a China made USB port. iPhone owners need not worry about such things, the USB sync cable  doubles as charger so it’s all good. The sheer convenience and power of the iPad provided the motivation for this mod. Productivity is when you do more and carry less items in the bag.

The finished ensemble—two cables elegantly connected and sealed with heat-shrink tubing.

Another reminder in case you missed this. This modification is unnecessary for owners of Nokia E72 — the USB data port is capable of charging the phone and Nokia includes a short cable for this purpose (too short in my opinion for practice use especially when you need to answer a call or send a text while the short cable is in use). My design factored this in and is long enough to not have to interrupt the phone’s charging or hotspot-in-use status!

The new USB cable is particularly useful in the car too with this dual USB car power adapter especially on seriously long journeys such as a 4-5 hours drive across the borders to Kota Kinabalu.

  1. Nice one.. I too am using my mobile e72 as a travelling hotspot that it drains power so fast. But the DIY, you did might give me ideas on how to deal with blinking battery bar. 🙂

  2. Hi Eddie, when you mentioned the E72, I remembered that Nokia includes a short USB cable for data transfers which also charges the phone. I updated the article to include reference to this.

    “This modification is unnecessary for owners of Nokia E72 — the USB data port is capable of charging the phone and Nokia includes a short cable for this purpose (too short in my opinion for practice use especially when you need to answer a call or send a text while the short cable is in use).”

    This modification takes into consideration the convenience of answering a phone call or sending a text message so I made it just long enough.
