Index Number: 11610 I'm looking for 'typical' wheel chair power usage figures. Ballpark is OK ( I'm looking for pseudo average power consumption, so if it's a bit off, it won't matter). A friend is in a chair, and about once a year or so finds herself sitting somewhere with a run down battery. My thought is to find a way to put a small 'emergency power' pack together such that she could throw a switch and have a few more minutes of power ... Enough to go 2 blocks and get in her van, then get out of the van and into the house, would be nice. What I'm looking for is some idea of what power factor is involved? (I could make a totally custom solution, but I'd rather try to make something a bit more general ...) If you know what a 'typical' power consumption is, I would like to know. Generally, if folks could state something like: 12V or 24V amps at full speed amps at 1/2 speed amp hours of batteries and normal range (in hours or miles) That would be very helpful. I don't normally read this new group, so if you could send email to ems@apple.com that would be best. Thanks. -- E. Michael Smith ems@apple.COM We all agreed that reducing the deficit was important. Unfortunately the Republican congress critters thought this meant 'Soak the Middle Class' and the Democrats thought it meant to 'Soak the Rich' while what the people wanted was less spending ...

The E&J power chair has a warning light when the power is getting low. Maybe instead of a reserve she needs a similar warning system. Sorta like a gas gauge on a car. My chair's batteries tend to wear out about every 18 months and need replacing even though they are rechargerable. Except for that, a nightly recharge will sustain me through a normal work day and an evening of activity around home. Hope this helps. -=joe=- -- Uucp: ..!{decvax,oliveb}!bunker!hcap!hnews!150!140!Joe.Chamberlain Internet: Joe.Chamberlain@f140.n150.z1.fidonet.org
