Powertrekk lets you get mobile power from ordinary water

by Mark R

I think that all of us have those mobile battery chargers for our cellular phone, in case we need that extra bit of juice. The problem is you have to remember to charge such devices, or you will be really screwed when you need them.

What if you had a battery that is powered on nothing but ordinary water? It is now named the Powertrekk, and it uses fuel-cell technology to convert hydrogen gas into electricity.

The secret is a thing inside the Powertrekk known as the Powertrekk Puck which holds the water and carries out the fuel based charge.

The Powertrekk is designed for USB powered devices, and you can use your USB charger on your mobile device for aiding in the charge.

I am sure that you are seeing the benefits of the PowerTrekk. I wonder if this company should use the slogan: “the last mobile charger that you will ever need to buy”.

The Powertrekk might be the answer to that age-old question for what you would have if you lived on a deserted island. Considering that I don’t need any sun or outlet, it has my vote. All I would need is a teaspoon of the water that surrounds the island. I’m not certain if I would have any cellular phone reception, but I would be entertained by a plethora of pre-loaded apps.

Of course, you will pay for this type of power, to the tune of $300. I still think that it is a good deal.

Without an endless supply of Pukks you’ll be out of power after the first charge. Did you even read your source article? This is cool technology but a terrible and expensive application of it.

I’ll take solar thank-you.

If you dig deep into their website you find that a Puck costs $4 and gives 4 watt-hours of electricity. This is not free power. In fact it’s expensive power – an alkaline AA cell costs around 50 cents and gives about 3 watt-hours.

Why would anyone invest capital to make this
and who/why would anyone buy it?

I’m not familiar with Sony batteries but the only ones I can find like that are NiMH rechargables which, of course, are more expensive. Shopping at 7/11 isn’t helping your wallet either.

A more fair comparison is Energizer or Duracell alkaline batteries which are $18 for 16! Average alkaline AAs hold about 2.5Wh so these are easily more cost effective than the puck. Also Instructables has a guide on how to build a cell charger from an Altoids tins using just AAs as the power source.

Excuse me, $8 for 16.
