Yes, and some people like those. Nothing bad to say about them here. I'm just trying to find out more aout ways of recharging more swiftly and efficiently from electrical outlets, (at least in this thread)

It's usually such a snail's pace sort of thing.

Which is fine in some situations.

Not in others though.

Pleny of juice is there at the outlets, and almost everything is in place for being able to get it done much more swiftly.

It seems like it would only take the right batteries and chargers. A fast-charging storage battery for portable electronics would be one approach. But I haven't seen any of those that fast charge well, and most of them seem to be the less-reliable Chinese ones.

Charging a set of reliable AAs or 18650s (or other batteries) in parallel would be workable. They could accept a lot more current this way.

Finding battery packs made to take a fast charge would be another approach -- some power tool packs charge very quickly, and are reliable and good for many charge cycles. But they come in odd voltages.

It would be nice to have a good battery pack like that, though, to recharge very quickly and then tap into as needed.

Twelve volts would make it easy, because of all the cigarette lighter adapters that could be used. It would be easy to get USB out (or micro-USB, etc.).

Maybe a 12-volt (or 12-volt compatible -- it could be a few volts higher and still work fine with the cigarette lighter adapter) battery from the power tool world, or from the radio-controlled vehicle world....

Maybe the Hobby King Turnigy Accucell 6 or Accucell 8 (or something similar), plus one of the quick-charging nano packs at the right voltage, plus a way to connect to a cigarette light socket -- that setup could work very well.

(I know people have used those packs for laptops, and they work well. They are very fast charging, and extend the run times of laptops. You just have to match the DC-out voltage of the laptop's power supply.)

Or maybe a 6-volt pack could give you direct USB out? If anyone can provide more information about these sorts of approaches, please feel free to post.

You could even bypass the cigarette lighter stuff and use one of their connectors directly -- the connectors that come pre-installed on those fast-charge battery packs from HK and similar outlets.

Those packs from HK are also favored by some of the electric bike builders because they provide the best bang for the buck.
