Can You Use Any Charger With Any Cell Phone, Notebook, Camera, or Tablet?
Every mobile phone, laptop, and tablet seem to come with their own charger. If you’re like me, you’ve probably compiled a number of chargers through the years. So the question becomes: is it safe to use a charger with your phone, laptop, camera, or tablet computer that isn’t the original manufacturer’s charger that came with the device?
Kinds of Chargers
In this guide, we will concentrate on three types of chargers: laptop chargers, micro USB chargers (these are used with telephones, tablet computers, and cameras), and Apple Lightning Connectors. Although some devices have chargers with a slightly different head or charging cable, these are the most common.
Laptop chargers are rather specific to the device they come with. However, there may be some generic chargers which boast the capability to be interchanged between laptops. This always requires changing of the charger”head” and might not be the optimal charging amperage or voltage to your device.
Micro USBs are designed to be interchangeable, and are standard in many smartphones, Android apparatus, and tablets. Micro USB chargers typically have the same voltage, but may draw different amps. I will explain this further later and how to know if the charger is safe to use (based on its recorded amps and voltage).
For older devices with a 30-pin charge port, a connector can be used to charge with the Lightning Connector.
In order for a charger to be used on a different device, it’s important that the plug of the charger (the”head”) fit securely into the charging port of the unit. Micro USBs are the same across the board so far as charging heads, while notebook chargers are often specific to both make and model. However, the plug fitting firmly is only 1 part of the equation.
Somewhere on 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 found at the base of the charger, where it would meet the wall. For the device you’re attempting to control, the voltage and amperage required will be found on the battery that came with the device or on the manufacturer’s website.
Voltage is how much power the charger will draw in the device, or just how much is being”pushed” to the device by the charger. A phone will usually pull up to approximately 5V, while a laptop can pull up to 25V. A charger must equal the voltage required by the device. This is important: drawing too high a voltage could short out the device and potentially even start a fire, while too low a voltage will fail to charge the battery.
Amperage is how fast power is”pulled” into the apparatus, or how much power is used by the device. The quantity of volts won’t ever change, but the quantity of amps that the system 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 max amount of amps that may be pulled by 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 device is paired with a charger that cannot support the amp necessity, it may burn out the power source and kill the device.
So if you have a modern USB device (smart phone, tablet, or camera) you can plug into a high-amperage USB port and enjoy quicker charging (as long as the voltage is equal). *Website Note: if you have an older device, it may not work with USB ports that employ the new Battery Charging Specification.
If The Micro USB Charger’s Voltage Isn’t 5v…
Some devices might have their voltage listed using a plus/minus on it like this: 5v +- 5%. If this is the case, you can 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% of 5v = 5.25 volts. So this means anything between 4.75 t0 5.25v is safe to use (as long as the amperage of the charger is equivalent to or higher than the device’s listed amperage).
An interesting thing to note is all chargers supply a higher voltage than the batteries that they charge. That’s pretty much how they work. There needs to be a voltage differential to produce the necessary current flow in the proper direction to charge the battery. When you look at your car, it has a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.
The issue with knockoffs, especially cheap knockoffs, is that they frequently don’t support the energy needs of the device, or aren’t built to keep a steady flow securely. This can cause damage to the device but can also pose a safety/fire hazard. Overall, it’s better to stick with the charger designed for the device you’re using.
Now You Know How To Safely & Effectively Swap Chargers
I hope this article was able to help you. Now you know how to safely and efficiently use a charger that did not include your smart phone, notebook, camera, tabletcomputer, or other apparatus. Be certain you follow what we said and you should be ready to go!
