Review: Electrovaya Power Pad External Battery
 By Michael Gray
For me one of the main limitations of a laptop based office/lifestyle is battery life.
Manufacturers advertise battery life spans of 3, 4, and 5 hours or more. However what they don't tell you is these times have very very little to do with real use conditions. Now I imagine there are people who use their computers without wifi or a Verizon card constantly on. They also don't run multiple applications like iTunes, Firefox, and Photoshop all day kicking the CPU utilization up fairly high. I don't know any of these people but I'm sure they exist.
I have a Toshiba Tecra M7 tablet PC, according to reviews I should be getting 3 hours of laptop battery life. In reality I usually get about 90 to 120 minutes. If I dim the brightness down and turn off both cards I can eek out almost to 180 minutes. The design of my laptop doesn't give me the flexibility of a high capacity battery. So while I'm not tied to desk, I am tied to a power outlet.
A few weeks ago while reading a Web Worker Daily blog post I came across the Electrovaya Power Pad which in reality is an external laptop battery. They have several different models the Power Pad 95, Power Pad 130, Power Pad 160 and Power Pad 300. The real difference is the estimated battery life of the units. This effects the size and color and case. I went with the Power Pad 95 which comes in a ridiculous silly looking baby boy powder blue casing. When you order this unit you will need to specify your laptop model so you get the proper connections, but more about that later.
Checking out the directions, which were a little rough on the translation, the correct way to use the unit is to chain it in between the laptop power cord and laptop. So your laptop power cord connects to the Electrovaya power cord. The Electrovaya power cord splits with one end connecting to the power pad and one end connecting into your laptop. I mentioned above that you needed to specify your laptop model when ordering, the Electrovaya power cord has interchangeable tips so it's compatible with a wide variety of laptops. When you are in "charging" mode the display will give you a charging message with a % of charge. When you are in "discharge" mode they recommend you use the Electrovaya first draining it completely before switching to your laptop battery, instead of waiting for your laptop battery to run out before connecting power pad. When the unit gets down to under 10% the LED display starts flashing, giving you some warning it's going to run out.
