I am a m12 user and have the m12 (only) vehicle charger model # 2510-20 . I’m overall not happy with it especially for the price. I’m wondering if the 48-59-1810 (m18 / m12 vehicle charger combo) is much better... Any experiences with the combo vehicle charger? - especially in regards to the following shortcomings of the (m12 only) vehicle changer: -Doesn’t charge all batteries, some oem large form factor batteries that work fine in multiple wall chargers give flashing error lights. -Takes forever, not practical to charge 4.0 & 6.0 batteries for an hour and 15 min to an hour and a half. I initially considered trying to use just a “compact power source” 48-59-1201 for m12 vehicle charging, like the type that is commonly used w/ heated jackets, but if my bulky 2510-20 isn’t up to snuff, I can’t imagine how slow one of those would be via USB cable. (2.5 hrs for a small battery). My old Makita 18v li-ion vehicle chargers, 10-15 year old technology could do much better. Any input greatly appreciated, thanks in advance
