Question: Are Power Adapters Interchangeable?

What happens if I use a 12v adapter on a 6v device?

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 use 4.5 V instead of 5v?

If the current draw was less, the voltage would be higher. So your 4.5 VDC supply might be that at 1.6A, but at 1 A, it might be 5 volts. … They’re very stable on the output voltage and can kick out an amp or so. It’ll work fine.

Can I use 85w charger instead of 60w?

Yes, with a caveat. The 85W adapter can be used inconsequentially with both models. It will provide ample power to both the MacBook Pro and MacBook, and will not damage the latter despite a higher-than-necessary wattage. … Note, however, that the 85W adapter will not charge a MacBook any faster than the 60W adapter.

How do you make a 12v power supply adapter?

Make 12v Power Supply Circuit Diagram:Take 4 Diodes and make a bridge, like diagram.Connect transformer output with diode, like diagram.Now connect 1000uf capacitor positive wire connect with positive wire and negative side connect with ground wire.and now connect 1k resistor and LED with positive and negative wire.More items…•

Can I use a different power adapter?

Your computer will use more power, in the form of higher amperage draw, when it’s working hard than when it’s not. (Voltage remains the same regardless.) Thus, as long as you replace your power supply with one capable of providing as much or more amps than the previous supply, you’ll be fine.

How do I know if my power adapter is compatible?

Any AC adapter is considered compatible with any device if it has all the following traits:The voltage of the adapter has to be identical. … The amperage (amps) of the adapter has to be equal or greater than the device. … The polarity of the adapter has to be identical.

Can I use a 5v 2a charger with a 5v 1a device?

The 2A port is capable of passing twice as many electrons per second. The current draw (Amperes) is controlled by the device you plug in. So if you plug a 1A device into a 2A charger, it will still only draw 1A.

Can a laptop be charged through the USB port?

If your laptop has a built-in USB-C port, then you’ll be able to charge your laptop via a USB-C cable – you just have to make sure the cable has a plug adapter (the box-shaped plug at the end of your phone charger than can plug into an outlet). Some laptops, in fact, use a USB-C cable as the primary charger.

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

19V is generally going to fry any device that was designed to run at 12V (especially consumer products). And while it’s not very likely it might also catch fire. For a AC adapter to work you will need one with the exact voltage (12V) and an equal or higher current rating (1.5A or more).

Is it OK to charge iPhone with 2.4 A?

There is no problem supplying that current from the 2.4 A adapter, since the phone controls the charging. With a newer iPhone, the internal circuitry and battery are capable of a higher charge rate, and the phone will use that when connected to a suitable power supply.

Can I use magsafe 60w instead of 45w?

Power adapters for Intel-based Apple notebooks are available in 45W, 60W, and 85W varieties. Although you should always use the proper wattage adapter for your Apple notebook, you can use an adapter of a higher wattage without issue. No. It will be at your risk if you try.

Can I use a 45w charger instead of 65w?

If the voltages match, the 45W should just charge a bit slower than the 65W. I would refrain from running anything heavy though, as it may be more load than the adapter can handle and it will drain the battery as well.

Can I use power supply with higher voltage?

2 Answers. Higher current (A) is okay because the device won’t use as much, but higher voltage (V) is going to “fry” it. Conversely, lower voltage is unlikely to cause damage since the device simply won’t have enough power, but lower current can cause trouble because the power supply cannot provide enough.

Is AC adapter and charger the same thing?

Adapters for battery-powered equipment may be described as chargers or rechargers (see also battery charger). AC adapters are used with electrical devices that require power but do not contain internal components to derive the required voltage and power from mains power.

Can I use a 10v adapter for 12v?

No it’s not safe for the most of cases. There are two reasons. Since newer adapter has more terminal voltage therefore device is liable to draw more current and bad thing is that newer adapter is ready to provide more current. That’s why things will get worse.

Are Apple power adapters interchangeable?

A: Short answer: Yes, you can. And if you want a faster charge, we encourage it. Apple explicitly approves of using its chargers across all devices that accept Lightning cables. … An iPad charge brick is rated to handle 2.1 amps, while the smaller iPhone charger is rated for just 1 amp.

What happens if I use the wrong voltage adapter?

Voltage too high – If the adapter has a higher voltage, but the current is the same, then the device will likely shut itself off when it detects an overvoltage. If it doesn’t, then it may run hotter than normal, which can shorten the life of the device or cause immediate damage.

Can I use a 6v adapter to power a 5v device?

If you’re mildly comfortable with electronic circuits, you could convert the 6V adapter to 5V. This can be done by hooking up the output of the adapter to a simple 5V linear regulator (the 7805) — the dropout would probably be low enough at 200mA to supply 5V.

Can I charge a 19v laptop with a 12v charger?

NO you cannot charge your 12V AGM battery directly with a 19V Laptop power supply. You need a battery charger. … So your fully charged state is about 13.8 – 14.5V. Putting two batteries in parallel does not change the voltage required to charge them it simply increases the current capability (increased Ah rating).

Are laptop power adapters interchangeable?

An AC adapter converts the higher voltage received from an outlet to the proper amount the laptop needs. Laptops can share power cords so long as the adapter’s wattage and connector tip is correct and compatible for each laptop you wish to use it with.

Can I use 12v adapter for 5v?

If you are talking about an ac adapter, then using a 9V or 12V adapter where 5V is required is not a good idea. 6V is only 20% off. I would not chance it but it might work.
