It appears to be able to charge a car or truck battery, and even a 12 volt riding lawn mower battery. The instructions say to use the 2Amp setting for the lawn mower batteries. 8Amp setting for standard batteries, and 12Amp setting for large capacity batteries lick a truck battery.

No. This product doesn't have it's own battery integrated into the design. This is a good thing because the Booster Packs you're talking about need to be replaced every 3-6 years because the battery inside them can no longer hold a charge to start a vehicle.
Just do a search for "Battery Booster Pack" to see what's out there. Something like a B&Decker VEC010BD would work great for what you need.

No, this hold a charge for cordless charging, if that is what you are asking. You have to connect directly to battery to charge whether out of car or in the car. They do make portable chargers, cannot think of a brand.

I think you are confusing this with a different type of product. There are some "portable power" units that can be used as a mobile power source and to jump start discharged batteries. This is not that type of product. This is a dedicated battery charger and as the other person responded, it should only be used in a well ventilated area with eye protection and away from children and any standing water.

You should not EVER charge a battery inside your house! The battery will release hydrogen gas as it charges. It can however, be connected to your motorcycle outside and charge the battery (12V only). It is NOT designed to crank the motor though.

not real sure, it has an indicator light that tells you when it's charging and when it's finished and also if it is maintaining, i know it would depend if your battery is super low or just needs topped off. i used the gel cell battery that was prob 11v and took about 3 hrs total, is a great little charger

Several variables influence this but I can offer some empirical results. It brought back a 3.5 year old 550 CCA battery from around 30% to fully charged and reconditioned in about 3 hours. It also brought a 6 year old 650 CCA truck battery from about 40% to full charge and reconditioned in about 9 hours. This battery had not been properly maintained in the intervening time. Ran up a new 850 CCA truck battery from 70% (as it left the store) to 100% in less than an hour. Fully charged and reconditioned a 2 year old 850CCA truck battery in a couple/few hours. Maybe not the fastest gun in the west, but a great balance between price and capability. Hope this helps...
