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’re 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 isn’t the original manufacturer’s charger that came with the device?
Kinds of Chargers
In this article, we will focus on three types of chargers: notebook chargers, micro USB chargers (these are used with phones, 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 frequent.
Laptop chargers are rather unique to the device they include. 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 best charging amperage or voltage to your device.
Micro USBs are designed to be interchangeable, and are standard in most smartphones, Android apparatus, and tablets. Micro USB chargers typically have the exact same voltage, but may draw various amps. I will 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
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 device. Micro USBs are the same across the board as far as charging heads, whilst laptop chargers are usually specific to both make and model. However, the plug fitting firmly is just one part of this equation.
How Voltage and Amperage Matter
Determined by the power brick of the charger you’ll get 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’re attempting to charge, the voltage and amperage required will be seen 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” into the device by the charger. A phone will usually pull up to around 5V, while a laptop 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 power is used by the device. The quantity of volts will never change, but the quantity of amps that the device pulls may change depending on how hard the unit is working. The number that you find on the battery that came with your device will be the maximum amount of amps which can be pulled from the device. If a device is paired with a charger which can’t support the amp requirement, it may burn out the power supply and kill the apparatus.
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 (so long as the voltage is equivalent ). *Site 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 recorded using a plus/minus on it like that: 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 apparatus can take 5v minus 5% of 5v = 4.75 volts OR 5v plus 5% of 5v = 5.25 volts.
An interesting thing to note is chargers supply 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 correct direction to charge the battery. When you look at your car, it’s a 12V battery, but typical alternators provide 13.8 to 14.4V charging voltage to the battery.
Stay Away From Cheap Knockoff Chargers
The issue with knockoffs, particularly cheap knockoffs, is that they often don’t support the energy needs of the device, or are not built to maintain a steady flow securely. This can cause damage to the device but can also pose a safety/fire hazard. Overall, it’s best to stick 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 assist you. Now you know how to safely and efficiently use a charger that did not include your smart phone, laptop, camera, tablet, or other apparatus. Make certain to follow exactly what we said and you should be ready to go!
