Hi I’m Harold Gomes,

The PowerTech Sigma Power center has helped to make life a little easier for me.

I’m in a wheelchair and recently had to start using a ventilator to assist my breathing. The “laptop” ventilator was small and light enough that it could be carried on the back of my chair—no ugly modifications were necessary to mount it. However, some modifications would be necessary to hold the clunky external rechargeable battery for the ventilator. The Powertech center proved to solve this problem—it’s so small that it fits in the side pouch of the vent’s backpack-like carrying case on my chair.

The PowerTech center transfers power from my wheelchair battery to my portable ventilator—without interfering in the way my chair operates. The wheelchair battery must be charged every night. Surprisingly, it gets me more power than the typical 9-hour external battery! Once, I was out somewhere 10 hours straight without any significant drain in power—the wheelchair power gauge indicted only 1/5 had been drained.

The best part is the fact that when I’m not moving—just watching TV or on the computer—the ventilator itself can be plugged into an electrical outlet. That way the chair battery power is saved.

The wheelchair battery needs to be replaced yearly (depending on battery size) ensuring that there won’t be any lack of power. The PTC never needs to be replaced!

What a great invention!

We want to thank the wonderful people at Richardson Products who brought us the Powertech Sigma. Becky is free now to work and play as hard and as long as she wants during the day without worry about her vent needing batteries. Prior to using the converter, we used 3 batteries a day and had to make sure we always had extra with us and had to make sure we were close to our extra battery or carry it around. We had to recharge three batteries every night (the insurance doesn’t reimburse for the charges either). It seemed that the battery was always running out at the most inopportune moments, often interfering with a family outing. But all of that has changed now. With the PowerTech Sigma, we go all day with no worries about batteries, no worries about getting too far away from our spare battery. We’re enjoying the freedom. The pictures you see show our busy little girl as we played at home, went to school, went in the van to a doctor’s appointment, and came home to enjoy the outdoor fun with friends. At the end of our busy day, Becky’s joystick still showed the charge almost complete. We lost only 1 or 2 bars on the wheelchair after a whole day ( which typically starts at 7 am and concludes at 9pm) of busy activity and continuous ventilator use. Since we don’t need the vent tray now for the battery, we are planning on eliminating the ventilator tray on Becky’s new wheelchair. We absolutely love the Sigma! Thank you again!
