Can You Use Any Charger With Any Mobile 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 quite a few chargers through the years. So the question becomes: is it safe to use a charger with your phone, notebook, camera, or tablet that isn’t the original manufacturer’s charger which came with the device?
Kinds of Chargers
In this guide, we’ll focus on three types of chargers: laptop chargers, micro USB chargers (these are used with phones, tablet computers, and cameras), and Apple Lightning Connectors. While some devices have chargers using a slightly different head or charging cable, these are the most common.
Laptop chargers are rather unique to the device they include. However, there may be some generic chargers which boast the ability to be interchanged between notebooks. This always requires changing of this charger”head” and may not be the best charging amperage or voltage to your device.
Micro USBs are theoretically designed to be interchangeable, and are standard in many 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 whether the charger is safe to use (depending on its listed amps and voltage).
Apple Lightning Connectors are standard on all new Apple devices, including iPads and iPods. For older devices with a 30-pin charge interface, 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 another device, it’s essential that the plug of the charger (the”head”) fit securely into the charging port of the device. Micro USBs are the same across the board as far as charging heads, whilst notebook chargers are often specific to both make and model. However, the plug fitting securely is just 1 part of this equation.
How Voltage and Amperage Matter
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 located at the base of the charger, where it would meet up with 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 into the device, or how much is being”pushed” into the apparatus by the charger. A phone will usually pull up to approximately 5V, though a notebook can pull up to 25V. A charger must equal the voltage required by the device.
Amperage is how fast power is”pulled” into the device, or how much electricity is used by the device. The amount of volts will never change, but the amount of amps that the device pulls may change based on how hard the device is working. The number that you locate on the battery that came with your device are the max amount of amps that can be pulled by the device. The amount found on the charger is how many amps can be pulled at once. In order to exchange chargers, the amp number on the charger must equal or exceed the amp number recorded on the device’s battery. If a device is paired with a charger that cannot support the amp requirement, it can burn out the power source and kill the device.
So if you have a modern USB device (smart phone, tabletcomputer, or camera) you can plug into a high-amperage USB port and enjoy quicker charging (as long as the voltage is equivalent ). *Website Note: if you have an older device, it might not work with USB interfaces that use the new Battery Charging Specification.
If The Micro USB Charger’s Voltage Is Not 5v…
Some devices might have their voltage listed with a plus/minus on it like this: 5v +- 5%. If this is the case, you may use a charger rated at 4.75 to 5.25v because that rating is telling you is that the apparatus can take 5v minus 5% of 5v = 4.75 volts OR 5v plus 5 percent of 5v = 5.25 volts. So this means anything between 4.75 t0 5.25v is safe to use (so long as the amperage of the charger is equivalent to or greater than the device’s listed amperage).
An interesting thing to note is chargers provide a higher voltage than the batteries that they charge. That is pretty much how they work. There has to be a voltage differential to produce the necessary current flow in the proper way to charge the battery. If you look at your vehicle, it’s 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 they frequently don’t support the energy needs of the apparatus, or aren’t built to maintain a steady flow safely. Overall, it’s better to stay with the charger made for the device you’re using.
Now You Understand 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. Make sure you follow exactly what we said and you should be ready to go!
