So lately I have been bombarded with these “Wirelessly Charge Your Shit!” ads from Best Buy for a product called “Powermat”. So I did some looking in to it and decided it is one big ass bucket of fail. They claim it to be convenient, an energy-saving, and neater.
First off, lets take a look at convenience. They say this because you won’t have to plug in your devices. You just set them on the mat, and it charges via electromagnetic induction. Well, that may be true, except they leave out this fact in the commercial… there are only Powermat cases that attach to devices for 8 devices. Yup… unless you own 1 of those 8 devices, you get to use the Powermat “Tip”. The “tip” is a white hunk of plastic that you plug in to your device’s USB port when you want to charge it. Wait… what? So you still have to plug in your phone to charge it?! Oh, and it must remain perfectly seated ON the powermat, WHILE it is plugged in? SERIOUSLY?!?! What kind of fail is this? So let me make sure I have this right. To use the powermat with my HTC Fuze, I would have to plug in the “tip” and set my phone on the mat, and leave it there. That means I can’t pick my phone up and use it while it is charging. How the fuck is that convenient? That sounds like a pain in my ass to me! I frequently use my phone while it is plugged in and charging, whether it is playing games, watching videos, surfing the web, or talking on it. The powermat would prevent me from doing any of those things.
Next, they claimed it saves energy by shutting off when you’re not using it.
I quote from this YouTube video:
“…you’re also using a lot of power especially when the products are not being charged, you know, nobody really unplugs their stuff “
Ole Ron claim that leaving your chargers plugged in is using energy. Well, this claim sounded like pure bullshit to me, so I tested it. Here is a picture of my HTC Fuze charger plugged in to a Kill-a-Watt power meter, showing how much energy is being used when my phone is not plugged in to it. Get ready for this… it may surprise you:
