I have two sutions machines, one that is stationary and one portable. I
love my portable one, it is called a DEVILBISS VACU-AIDE, its just alittle
bit bigger the a square kleenex box. Its very light and easy to carry, its
comes with its own carrying case, and charging adapter. I've never had a
problem with it, well execpt one but it was sorta my own fault. I kinda
dropped it on the ground and cracked the peice the suction tubing goes on,
just call me a clutz hehe. I pulg it into the wall outlet about once aweek
overnite to charge the battery and the charge lasts me for about a month,
but then I only use it when I go out someplace. Basically the amount of
time the charge will last depends on how much you use the suction machine.
Hope this is of some help to you.
Huggs,
Becky
