Can You Use Any Charger With Any Cell Phone, Notebook, Camera, or Tablet?
Every cell phone, notebook, and tablet appear to come with their own charger. If you are like me, you have probably compiled a number of chargers through the years. So the question becomes: is it safe to use a charger with your phone, notebook, camera, or tablet computer that is not the original manufacturer’s charger that came with the device?
Kinds of Chargers
In this article, we will concentrate on three types of chargers: notebook chargers, micro USB chargers (these are used with telephones, tablets, and cameras), and Apple Lightning Connectors. While some devices have chargers using a slightly different head or charging cable, these are the most frequent.
Laptop chargers are fairly specific to the device they come with. However, there can be some generic chargers which boast the ability to be interchanged between notebooks. This always requires changing of this charger”head” and might not be the best charging amperage or voltage for your device.
Micro USBs are theoretically designed to be interchangeable, and are standard in most smartphones, Android devices, and tablets. Micro USB chargers typically have the same voltage, but may draw various amps. I’ll explain this further later and how to know if the charger is safe to use (depending on its recorded amps and voltage).
For older devices with a 30-pin charge port, a connector can be used to control the Lightning Connector.
The Plugs Must Be The Same
In order for a charger to be used on a different device, it’s important that the plug of the charger (the”head”) fit snugly to the charging port of the unit. Micro USBs are the same across the board so far as charging heads, while laptop chargers are often specific to both make and model. However, the plug fitting firmly is only 1 part of this equation.
How Voltage and Amperage Matter
Determined by the power brick of the charger you’ll find a label with the charger’s voltage (V) and amperage (A). For other types of chargers, like a smartphone charger, this information is usually located at the bottom of the charger, in which it would meet the wall. For the device you are trying to charge, the voltage and amperage required will be found on the battery that came with the device or on the company’s website.
Voltage is how much power the charger will draw into the device, or how much is being”pushed” into the device by the charger. A phone will usually pull up to approximately 5V, though a laptop can pull up to 25V. A charger must equal the voltage required by the device.
Amperage is how fast power is”pulled” to the apparatus, or how much power is used by the device. The amount of volts will never change, but the amount of amps that the device pulls may change depending on how hard the device is working. The number that you find on the battery that came with your device are the maximum amount of amps that may be pulled from the device. In order to exchange chargers, the amp number on the charger must equal or exceed the amp number listed on the device’s battery. If a unit is paired with a charger which can’t support the amp necessity, it can burn out the power source and kill the apparatus.
So for those who have a modern USB device (smart phone, tabletcomputer, or camera) you can plug into a high-amperage USB port and enjoy faster charging (as long as the voltage is equal). *Site Note: if you have an older device, it might not work with USB ports that employ the newest Battery Charging Specification.
If The Micro USB Charger’s Voltage Is Not 5v…
Some devices may have their voltage listed using a plus/minus on it like this: 5v +- 5%. If this is true, you may use a charger rated at 4.75 to 5.25v because that score is telling you is that the device can take 5v minus 5 percent of 5v = 4.75 volts OR 5v and 5 percent of 5v = 5.25 volts. This means anything between 4.75 t0 5.25v is safe to use (as long as the amperage of the charger is equal to or greater than the device’s listed amperage).
An interesting point to note is all chargers provide a higher voltage than the batteries they charge. That’s pretty much how they work. There needs to be a voltage differential to generate the necessary current flow in the proper direction to charge the battery. When you look at your vehicle, it’s a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.
Stay Away From Cheap Knockoff Chargers
The issue with knockoffs, especially cheap knockoffs, is that they frequently don’t support the power requirements of the device, or aren’t built to keep a steady flow securely. Overall, it’s best to stay with the charger made for the device you’re using.
Now You Know How To Safely & Effectively Swap Chargers
I hope this article was able to assist you. Now you know how to safely and efficiently use a charger that did not come with your smart phone, laptop, camera, tabletcomputer, or other apparatus. Make sure you follow exactly what we said and you should be ready to go!
