Question: What's the difference between DC10WA and DC10WB chargers?
Document: Great service, delivery, and price! The chargers were what we needed.
works quickly and just as described. hAVE TO PUT MORE WORDS IN HERE JUST TO SUBMIT. STUPID CONFIGURATION. HOW MUCH CAN YOU SAY AVOUT A DAMNED BATTERY CHARGER
the price was ok, delivery was timely. Thanks. This allows me to have two batteries charging and give me enough time to do the whole house
Yep it charges batteries ... I'm reasonably certain chicks dig it ... My makita driver seems to like the juice it puts into it's batteries ...
The shorter charge time is worth it, in my book.
The charger was just in a Baggie in a box with A bubble, I'm giving this as a Father's Day gift and I'm embarrassed to give it because it looks like I got it from my other father to give to my husband it looks refurbished I have no directions or hazard info how am I gonna wrap it? I don't even know if it works cuz it's a gift
Purchased the 'tool' part thinking it was a complete vacuum system---then learned it needed a battery, then found out it needed a charger. Guess I need glasses? Battery charges and works&#8230;though I would suggest reading everything more carefully than I did and perhaps purchasing a hand-vac that has all things included.
It's very handy. And thanks to red and green lights, you know when it's charged. I use it all the time.
It was just like the original one eyeballs I plugged it up it charge the batteries quick and I will recommended again
I've bought a Makita combo, with one impact drill and a driver, which came with just one charger. With this charger and 2 more spare batteries, I don't have to wait while charging batteries, I always have at least one set of batteries fully charged to use with my tools.
Answer: no
