1- Multiply the battery amp-hours (ah) by battery volts to convert the battery capacity into watt-hours (Wh). Let''s suppose you have a 12v 50ah battery. Battery capacity in Wh = 50 × 12 = 600wh. 2- Multiply the battery …
Battery Capacity or Watt-Hours (Wh) = Amp-Hours (Ah) × Voltage (V) In the case of a 100Ah 12V battery, we get: 100Ah 12V Battery Capacity = 100Ah × 12V = 1,200Wh. Now, this 1,200Wh battery capacity is the most useful piece of information when it comes to determining how long will a 100Ah battery last.
If you happen to surpass that 180 Watt ceiling, then your fuse will blow. However, there''s nothing to worry about when it comes to USB car chargers, which outputs a maximum of 24W or lower. Hopefully, now you have a better understanding of the common car charger specs to help you when you''re looking to buy your next charger.
However, the voltage of a battery does affect the charger''s output. For example, if you have a 5V charger and a 3.7V battery with a capacity of 2,000mAh, the charger will output 5V, but the battery will only receive 3.7V. This means that the charger will have to output more current to charge the battery to its full capacity.

Step 1: Choosing a Charger Based on Battery Type. To select the right charger, you need to know your battery''s chemistry. Common battery types found in most applications are maintenance-free, wet cell (flooded), AGM (absorbed glass mat), gel cell, VRLA (valve-regulated lead acid), or lithium.
The size of a solar battery charger you need depends on two things: the battery''s capacity (measured in Ah or mAh) and the solar panel''s power output (measured in Watts). As a rule of thumb, a solar charger with an output of 10 Watts should be sufficient for a small to medium-sized 12V battery.
If you notice unusually high power consumption or rapid battery drain, understanding how many watts your device uses can help you identify the cause. You can then take appropriate steps to rectify the issue, such as closing power-draining apps or adjusting settings that may be causing excessive power consumption.
So, a 120-watt charger will have used about 17/60 of its input in an hour. So, at 50% efficiency, a 120-watt version will consume about 68 watts of power (240 watts x 17/60). At the same consumption rate, a 120-watt charger will use …
