Cordless random orbit sander question

[Louis Brandt]

Hello,
I'd like to have a random orbit sander, but I'll only need it for minor applications, so I'm wondering whether a cordless model will be adequate. I'm considering buying the Ryobi 18V OnePlus random orbit sander to go with my other Ryobi 18V OnePlus tools. I'm using the Ryobi cordless tools with NiCD batteries, not LiOn.
Are there any negatives associated with cordless random orbit sanders?
Thanks,
Louis

I've not used one but offhand I should think it would not have the staying power for any kind of reasonable-sized job. Unless you can get by with a lot less sanding than most.

How long do they claim it can go on one charge?
