A small battery charger typically uses between 5 to 50 watts, depending on the type and capacity of the batteries being charged. For example, a charger for AA or AAA rechargeable batteries generally consumes around 5 to 10 watts, while chargers for larger batteries, like those used in power tools or electric vehicles, can use significantly more power. It's important to check the specifications of the charger for exact wattage.
Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
Assuming 100% efficiency, a 36-volt battery charger would use 36 watts per hour to charge the battery fully. However, it's important to consider that chargers are not 100% efficient and may draw slightly more power from the wall.
A 5V 2A charger outputs 10 watts of power.
The wattage used to charge a power drill battery typically varies based on the battery's voltage and the charger’s output. Most standard power drill batteries range from 12 to 20 volts, and chargers can have outputs between 1 to 3 amps. Using the formula (Watts = Volts x Amps), charging a 18V battery at 2A would use about 36 watts. However, the actual power consumption can vary depending on the efficiency of the charger and the battery's state of charge.

The Makita Battery Charger is used for Makita batteries. This battery charger is capable of charging many batteries depending on the voltages for the batteries.
To determine the watts needed to run a 12-volt drill charger, you can use the formula: Watts = Volts x Amps. If you know the amperage of the charger, you can multiply it by 12 volts to find the wattage required.
No. The speed at which the charger will charge the battery is determined by how many amps the charger outputs.
It depends on what kind of charger your talking about. Im assuming some type of smart phone charger... typically about 5.1 volts at .8 to 1 amp.... current ( amps) times voltage equals power (watts) so.. around 4 to 5 watts
No, an automobile battery charger outputs 12 Volts. This is far too many volts to charge a 5 Volt battery. You would destroy the 5 Volt battery with this charger.
An iPad charger typically uses 10 to 20 watts, depending on the model and the specific charger. Older iPads usually come with a 10W or 12W charger, while newer models, especially iPad Pro versions, can use chargers up to 20W or more. Apple’s latest USB-C iPad chargers are often rated at 18W or 20W, which allows for faster charging. You can find the exact wattage on the charger itself or in the iPad’s specifications.
You cannot compare these two totally different things. As far as amperage the charger puts out more amps if it is an auto battery charger and also puts out 12 volts. If you are talking about a 9 volt battery charger then the battery may or may not be more powerful, it depends on how many mii-amps the charger is putting out.
