    Portable chargers

    I've had the fortune of traveling to many great places, with activity after activity planned, only to have my plans ruined by a sudden drop in my chair's battery level. My chair charger is a bit bulky to be lugging around, and so I wondered if there was any smaller options available?

    I've been using a Soneil 2412sr constant current SuperCharger since the 90's with great results and about the size of a brick. http://soneil.com/product/model-2412sr/

    We had one for my mother's Permobil, but it was a long time ago (2007). I think it was this one though:

    Only downside of this one was that it took a lot longer to charge the battery than the standard charger we used at home, but it worked for daily charging during the night just fine.

    Those are GREAT! My wife's chair had bad charger come with it new and DME just swapped it for Soneil with fan, guess it's a SuperCharger not sure. That puppy charges fast!!!! It still in use through few more chairs.
    We have a converter in van and plug Soneil into it to charge while traveling. Remember even in Las Vegas that both our chair's batteries were on way out, been putting off getting replaced and we'd plug up in casinos or shopping galleries. Didn't take long to recharge both chairs with 1 charger.

    Big/bulky chargers common with many chairs typically have the advantage of being pretty robust (ventilated actively or passively to help keep component life high). But, you can trade size and ampacity (and dollars) in lots of different ways. You can also look to changing your battery chemistry to get more life from them ($$).

    What are you looking for in terms of charging capacity (times)? Presumably, all "domestic" locations?

    I just built a charger for a colleague that ran off a "power socket" (I guess they no longer call them "lighter sockets"!) so he could rely on his vehicle as the "charging station" (I wired an additional socket in the vehicle for convenience of access). I imagine you can buy similar OTC.

    What about a Battery Tender. They have a lot of stuff on their web site.

    Thank you all for the info. As far as charging times, basically I would hope to find something that in an hour could provide an adequate charge to allow me to continue with my plans. I know, kinda vague.

    How quickly does it charge?
