Can You Use Any Charger With Any Mobile Phone, Laptop, Camera, or Tablet?
Every cell phone, notebook, and tablet seem to come with their own charger. If you are like me, you’ve 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 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. While some devices have chargers with a slightly different head or charging cable, these are the most common.
Laptop chargers are rather unique to the device they come with. However, there may be some generic chargers that boast the ability to be interchanged between laptops. This always requires changing of this 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’ll 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 using a 30-pin charge interface, a connector can be used to charge with the Lightning Connector.
The Plugs Must Be The Same
In order for a charger to be used on another 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, whilst notebook chargers are often specific to both make and model. However, the plug fitting securely is just 1 part of the equation.
How Voltage and Amperage Matter
Determined by the power brick of the charger you’ll get a tag 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, where it would meet the wall. For the device you’re trying to control, 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 in the apparatus, or how much is being”pushed” to the device by the charger. A phone will usually pull up to around 5V, though a notebook can pull up to 25V. A charger must equal the voltage required by the device.
Amperage is how quickly power is”pulled” to the apparatus, or how much power is used by the device. The amount of volts will never change, but the quantity of amps that the device pulls may change depending 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 from the device. 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, tablet, or camera) you can plug into a high-amperage USB port and enjoy faster charging (as long as the voltage is equal). *Website Note: if you have an older device, it may not work with USB interfaces 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 that: 5v +- 5%. If this is true, you can use a charger rated at 4.75 to 5.25v because that rating is telling you is that the device can take 5v minus 5% of 5v = 4.75 volts OR 5v and 5% of 5v = 5.25 volts.
An interesting point 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 generate the necessary current flow in the correct direction 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.
Stay Away From Cheap Knockoff Chargers
The problem with knockoffs, especially cheap knockoffs, is that they frequently don’t support the energy needs of the apparatus, or are not built to keep a steady flow safely. Overall, it’s best to stick 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 include your smart phone, notebook, camera, tabletcomputer, or other device. Make certain to follow what we said and you should be good to go!
