A nerd’s survival kit – extra power for your smartphone

PowerPackThe arrival of the smartphone (iPhone, Android) etc is a blessing for the true nerd who now can be constantly online and up to date with important things (aka the Internet). On a professional level it is a way of giving good service to your customers be being able to quick reply to emails etc.

The problem with the smartphones are battery capacity. With a couple of apps running and checking things now and then you can easily be drained in 2-3 hours. For an upcoming trip abroad I started to investigate solutions. I looked at solar cell chargers which turned out to be quite big in order to supply sufficient current. They also have built in batteries. Since I will not be hiking in the himalayas I figured the thing I really needed was extra battery capacity. I will after all stay in hotels where there is possibility to recharge over night.

PowerPackMy choice fell on a 5 Ah PowerPack from Kjell.com. One thing to investigate thoroughly before choosing the pack is that it can deliver enough current to charge the smartphone. It will require at least 1 A and there are power packs on the market with lower current ratings supposed to be used only with MP3 players and similar. If you want to do this stunt with an iPad you need even more current (2 A).

First I tried to use up my phones battery and then hook it up to the powerpack to recharge it. This wasn’t a good idea since a dried out smartphone will consume too much current which the powerpack can’t deliver. So instead, already in the morning when leaving my hotel, I hooked the smartphone up to the powerpack and run it on both the internal battery and the powerpack. This way my power lasted for the entire day.

When abroad I don’t have data roaming (otherwise the charges would be sky high). There is a little smart Android app called WeFi. It runs in the background and scans for open hotspots and connects to any it finds, no matter if it has an SSID that is not already known by your device. Once hooked up it verifies if it has Internet connection and plays a little sound. Then your phone pulls down new emails etc. Just walking by for example a McDonalds and you’re all up-to-date again 🙂
