Can I Use 12V Adapter For 7.5 V?

1 Answer. Show activity on this post. You should never use a significantly higher voltage rating adaptor on any kind of electrical device.

Can I charge a 7.5 V battery with a 12V charger?

No. You need a 13.8 V charger with current limit to charge 12V battery with current limit set to 10% of the AH capacity.

What happens if I use a 12V adapter on a 5V device?

The device will very likely burn out. In addition, depending on what the device is and the capacity of the 12V supply, connecting a 12V supply to a device rated 5V max could lead to a hazard – fire, explosion, etc.

What happens if I use a 12V adapter on a 9V device?

If you have a 12V adapter, you might wonder whether you can use it to power your 9V guitar pedals. In most cases, you cannot use a 12V adapter to power a 9V guitar pedal. Using a 12V adapter on a pedal designed to only handle 9V can completely destroy it.

Can I use 9V adapter for 7.5 V?

However if the device is relying on the regulated voltage from the adaptor and has no internal circuit to control or limit overvoltage, then that 9v adapter may damage your device. That said, there are 7.5v devices designed with tolerances wide enough that the 9v you provide it won’t make any difference at all.

Can I use a 12 volt charger on a 7.2 volt battery?

If it is a lead/acid “12V” charger, it likely has a nominal output voltage of higher than 12 volts, and if it is above, say, 14.5V, you could charge two 7.2V batteries in series. If the output is actually 12.0V, then you may still be able to charge one battery if you include a resistor in series.

What charger do I need for a 12V 7ah battery?

As a general rule of thumb when selecting a charger for a lead acid battery, match the voltage and use one that is no more than 20% of the capacity rating of the battery (at a 20hr. rate). Example; to charge a 12 volt / 7.5Ah battery, select a charger with a maximum charge output of 1.5 Amps (7.5 x 0.20 = 1.5).

Can I use 4.5 V instead of 5V?

It’ll work fine.

Can I use 10V adapter for 5V?

NO! you cannot use a 10V charger instead of a 5V for your mobile. Since the mobile is rated to be used with 5V charger, using one with 10V can be hazardous and may also cause irreparable damage to mobile.

Can you use a 12V charger on a 5V?

No, u can’t run a 12V motor on 5V supply because 5V supply can not provide much current to motor to rotate.

Can I use 12V Adaptor on 8v?

No, it will cause too much current draw at 8v, when it’s requirement is 12 V +/- 10%. So, anything between 8.8 V and 13.2 V would be OK. But , 8.0 is too low, and would cause over heating of the DC to DC converters built in to the devices that use 12V.

Can I use 12V adapter for 18V?

Can I charge an 18V battery with a 12V charger? – Quora. Surprisingly it is possible and this type of thing is done somewhat frequently. The voltage can be stepped up with a boost converter. Large voltage boosting is inefficient, but boosting by just a few volts isn’t too inefficient.

Is it OK to use higher voltage adapter?

Using a higher current charger (than the laptop is rated for) will not cause damage to the laptop; as stated earlier. The device will only draw what it requires from the power pack.

Can I use 12V 1.5 A for 12V 2a?

Yes, there will be no problem. As long as the voltage of 12 Volts is same, it will work perfectly fine on a 12 Volt 1 Amp power supply as it would on a 12 Volt 0.17 Amp power supply.

Can I use a 24v power supply on a 12V?

Originally Answered: Can I use a 24v power supply to power 12v LED strips? No, this will not work. The LED strip light is constant voltage light, so the power supply output voltage have to match the working voltage of the LED strip light.

Can I use a 12V power supply on a 6V?

If the device has its own internal switching regulator, the voltage probably won’t be a problem, but since the 12V power supply has a lower maximum power (12V * 0.35A = 4.2W, and 6V * 1A = 6W), it may draw too much power and the power supply will be damaged.

Can I charge a 7.4 V battery with a 12V charger?

No. The 12V charger is almost certainly designed to charge lead acid batteries. Its 2A rating means it will be able to maintain an initial charge of 2A when used for charging a six cell 12V lead acid battery.

Can I charge a 7.2 V battery with a 6V charger?

A 6V supply will not charge a 7.2v battery. It sounds like you are talking about little DC power supplies or battery eliminators, not a battery charger. You definitely want to get a charger designed for charging NiCd and NiMH batteries.

Can I charge a 7.2 V battery with a 9.6 V charger?

No. assuming your 7.2V pack is lithium, a 9.6V charger is not designed to safely charge a lithium battery of any kind.

Can a 12V 7Ah battery be charged?

Yes you can. A 12v charger can charge any 12v battery. The difference is your scooter battery is 7ah (amp hours, for those reading who may not know) and a car battery is hundreds of amp hours, so it isn’t going to take very long to charge the scooter battery compared to a automobile battery.

What is a 12V 7Ah battery used for?

Expert power sealed lead acid batteries: used for alarms, Uninterruptible power supplies), lighting equipment, general electronics, emergency systems, medical devices, electric scooters, solar collectors, wheelchairs and many other applications.
