Battery Drill Charger Wattage

[Blue Fox]

Hello all,

Anyone know roughly the rated wattage of the average battery drill charger. The reason I ask is I'm going to get an inverter mainly so I can print off certs invoices etc whilst at site from laptop but thought it would be useful to be able to charge up my drills, screwdrivers etc whilst on way to jobs occasionally if I've forgotten to charge them at home so want an inverter large enough to do this comfortably without getting a huge big thing.

Thanks

Based on the readings from a customers smart meter, mine runs at about 90W (to charge up 2.4Ahr Li-ion)

i have a 300w inverter for the chargers - i often have 1x 12v & 1x 36v battery on charge at the same time without any problem

My 150W just about does the Makita 24V charger.

If you're using a laptop and printer why the inverter? I have a battery powered wireless colour printer with the laptop.

Main reson is the battery printers cost a lot more than the normal desktop ones and I have a spare printer at home at moment as recently upgraded my home one for better photo printing. Plus I'm terrible at remembering to charge things - hence the nedd to charge batt drills up on way to jobs!!

that and batteries often need charged on the job too, and you dont always have time left to fully charge before you go to next job

This may sound daft.. but have a look on the bottom of your chargers?

or try a few manufactures web-site tech specification pages...

Otherwise it can be a how long is a piece of string sort of question...

A little Bosh screwdriver thing I have is only 13watts...

another Hitachi Drill Driver is 70watts...

So just working up the scale.. bigger the drill, bigger the batteries, shorter the charge time..

More watts needed me thinks!

If you are needing between 0.5A and 1A worth of charging current..

you have got to be talking 115Watt to 230Watt power.
