When I was in Redmond three months ago, I got an iSun Solar Charger and while the weather wasn't the best the last months, I remind it now, since we have much more sun finally.

The iSun is a complete solar charger for small electronic devices such Pocket PCs, Smartphones and cellular phones. It comes with plugging accessories that will enable you to run over 90% of all small electronics - at least it fits into all my Pocket PCs as well as into the Orange SPV.

iSun can run devices requiring less than 2 watts. It can help run any small electronics over 2 watts by connecting multiple iSun units together. Daisy-chaining the unit with another one can double the power output.

The iSun unit can be used in all sunny conditions. Naturally, the brightest conditions will yield better charging output.

iSun comes with 7 plugs that fits in most electronics found on the market today


  • Wattage: 2.2 watts
    Isc = 290mAmps@7.6 volts or 145mAmps@15.2 volts
    Voc = 15.2 VDC (12V setting) or 7.6 VDC (6V setting)
  • Dimensions: 7.25" x 4.5" x 1.25" (184mm x 114mm x 32mm)
  • Weight: 11 oz (311 grams)
  • Temperature Range: -40°F to 176°F (-40°C to 80°C)

Using iSun

Using it is pretty much the same as charging your mobile device with a power cable of USB Sync and Charge cable:

  • Find the right plug for your device.
  • Connect the iSun with you device.
  • Put your Pocket PC or Smartphone together with the connected iSun into a bright area, this must not directly in the sun but a shadowed area works as well.
  • Press the yellow button on iSun. If the green LED switched on iSun works/get enough sun light and your mobile device should starts charging.

Examples of additional talk time and standby time using iSun

Based on a three hours charging you get the following additional time with your cell phone - according to iSun:

And I can say that it really charged my Dell Axim and Orange SPV so it really works.

Final Conclusion

iSun is a nice piece of accessory for Windows Powered Mobile Devices such as Pocket PCs and Smartphones. Maybe you think now that everywhere you go a power outlet is available but it isn't, at least that's my experience.

For example when I was two years ago in Turkey for a one week boat trip, the availability of power was pretty limited and 10 people "righted" for one power outlet in the evening when 220 V power was available for several hours. With this iSun you become independent, doesn't matter if you are on a boat trip, camping or anywhere else. So there is for sure a reason to use it.

On my next outdoor trip, iSun will be part of my "gadget-bag" for sure! :D

iSun costs around US$79.99 and is available for online order from different online shops from all over the world.
