Is it OK to use a higher amp charger?

Is it OK to use a higher amp charger?

We recommend higher amperage to ensure cooler power supply and optimal charge time. If you get a charger with amperage less than your original power supply, you risk overheating your charger, burning it and in many case your device will stop functioning and/or charging.

Does it matter what watt charger I use?

No. The power rating of a charger has no bearing on the life of the battery nor the consumption of power by the device. A higher wattage charger only means it can supply up to the specified amount of current, not that it will push that amount of current to the device.

Does it matter what battery charger I use?

Make Sure to Select the Correct Charger Output As a rule of thumb, your charger should be 10% minimum of your battery’s Ah rating. This means a 100Ah battery would need a 10 Amp charger minimum. You can increase the battery charge amp if you need the battery to be charged at a faster timeframe.

Can I use 1a charger for 0.5 a device?

The amperage rating of a charger or power supply is the maximum it can supply. A device being charged will only take as much amperage as it requires. If your device needs 0.5 amps to charge, and your charger is rated at 1.0 amps, only 0.5 amps will be used. Charging may not work at all.

Can I use a 65 watt charger on a 90 watt laptop?

If your laptop was supplied with a 65W charger we know that the laptop will never draw more than 65W, so you can use a 65W, 90W,120W, 150W, 180W, 240W or higher charger. You can not use a charger with a lower wattage rating.

Can I use a 90 watt charger on a 120 watt laptop?

The 120 Watt should last longer and be less prone to failure when used at a lower power output and my choice – However the 90 watt should also work fine. You should not use a 90 Watt brick if you need a 120 Watt brick.

How many amps should my battery charger be?

Most battery manufacturers recommend sizing the charger at about 25% of the battery capacity (ah = amp hour capacity). Thus, a 100 ah 12 volt battery would take about a 25 amp 12 volt charger (or less). Larger chargers may be used to decrease charge time, but may decrease battery life.

Can a battery charger be too big?

You can’t have a battery charger which is “too big”. The batteries will take what they’re going to take in the way of amperage and no more, provided that the charging voltage is correct.

Can I use 300ma instead of 500mA?

As long as the voltage output is correct for your unit it is okay.

Can I use a 12v power supply on a 19V?

No, don’t use it! The PSU will supply 19V (“voltage source”) and will probably damage the load. There are PSUs that limit output current by dropping/regulating the output voltage (which then can be considered a “current source”), but as long as the required current isn’t constant that wouldn’t work either.

What happens if my Charger has only 0.5 amps?

The problem, of course, is the reverse: if your device needs 1.0 amps, but your charger is rated at only 0.5 amps, then any of several problems could result: Charging may not work at all. The device may charge extremely slowly. The power supply may overheat.

What happens when there is too much power in a charger?

Too much power generates excess heat, which is the bane of sensitive electronics. The other important term to know is polarity. For direct currents, there is a positive pole (+) and a negative pole (-). For an adapter to work, the positive plug must mate with a negative receptacle or vice versa.

Can a charger have more than one amperage?

Amperage The amperage provided by your charger must match or exceed what the device being charged requires. The amperage rating of a charger or power supply is the maximum it can supply. A device being charged will only take as much amperage as it requires.

How manymah does a universal power adapter need?

(Product needs 600mAh, universal power adapter only sends 300mAh) The unit, mAh or milliampere-hour]
