All new Apple devices come standard with a lightning connector. This includes iPods and iPads. Older devices have a 30-pin charge port, a connector can be used to charge with the Lightning Connector.
The Plugs Must Be The Same
To use a charger on a device it was not made for, it is important to make sure that the charger plug (or head) fits easily into the charging port of the device. Micro USBs are the same all around as far as charging heads are concerned, while laptop chargers tend to be specific
to their make and model.
However, having the plug fit securely is only one part of the equation.
Voltage and Amperage Matter, here’s how:
The charger’s voltage (V) and amperage (A) can be found on a label somewhere on the power brick of the charger. The charging brick on laptop chargers is often halfway down the charger and typically looks like its namesake – a brick.
On a smartphone, the information is normally found at the bottom of the charger, where it meets the wall. For the device, you are attempting to charge, the voltage and amperage required will be found on the battery that it came with or on the manufacturer’s website.
The amount of power the charger will draw into the device, or how much is being “pushed” into the device by the charger is called voltage. A normal cell phone usually pulls around 5V, while a laptop can pull as much as 25V. A chargers voltage must equal the voltage required by the device.
Remember this: drawing too much voltage could short the device out and maybe even start a fire! Too low a voltage will not charge the battery.
How fast power is pulled into the device, or how much power the device uses is called amperage. The amount of volts will not change, however, the amount of amps that the device pulls can change depending on how hard it is working. The number can be found on the battery that came with the device and will be the max amount of amperage that it can pull.
The number on the charger is how many amps that it can pull at once. To be able to swap chargers, the amp number on the charger must meet or exceed the amp number displayed on the device’s battery. If a device is used with a charger that cannot support the amperage requirement, it can burn out the power supply and ruin the device.
If you have a newer device that uses USB like a smartphone, tablet, or camera, you may connect it to a high-current USB port and charge it faster (as long as the voltage is the same).
*Note: If your device is an older model, it may not work with USB ports that use the new specification for charging batteries.
If the Micro USB Charger voltage is not 5v…
For some devices, the voltage is indicated with a plus/minus as follows: 5v +- 5%. If this is true, then you can use a charger with a nominal voltage of 4.75 to 5.25 volts, because this nominal voltage tells you that the device can take 5 volts minus 5% of 5 volts = 4.75 volts OR 5 volts plus 5% of 5 volts = 5.25 volts. This means that anything between 4.75 and 5.25 volts is safe (as long as the current rating of the charger is equal to or higher than the specified current rating of the unit).
It is interesting to note that all chargers deliver a higher voltage than the batteries they charge. This is pretty much the way they work. There must be a voltage difference to create the necessary current flow in the right direction to enable a charge on the battery. Most likely your car has a 12V battery, but typical alternators deliver 13.8 to 14.4V charging voltage to the battery.
Look out for low budget cut-off chargers.
The problem with imitations, especially cheap imitations, is that they often cannot handle the power requirements of the device or are not designed to maintain a stable and safe flow of energy. This can damage the device, and also pose a safety/fire hazard. Overall, it is best to use the charger designed for the equipment you are using.
Now you know how to replace chargers safely and effectively.
I hope this article has helped you to realize how to safely and effectively use a charger that was not included with your smartphone, laptop, camera, tablet, or other devices. Make sure you follow our instructions and you should be ready to go!
But what happens when your battery ages and doesn’t work well? Well, you’ll have to use other methods and recondition it! And this is exactly what we show you in the EZ Battery Reconditioning Program.
If your a battery on any of your devices including your phone, car, truck, or laptop, or anything else is getting old or has even died, watch this video to learn how you can easily recondition your batteries yourself at home!
