Can You Use Any Charger With Any Mobile Phone, Notebook, Camera, or Tablet?
Every cell phone, laptop, and tablet seem 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, laptop, camera, or tablet that is not the original manufacturer’s charger that came with the device?
Types of Chargers
In this article, we’ll 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 using a slightly different head or charging cable, these are the most frequent.
Laptop chargers are rather specific to the device they come with. However, there can be some generic chargers that boast the capability to be interchanged between laptops. This always requires changing of this charger”head” and may not be the best 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 exact same voltage, but may draw various amps. I will explain this further later and how to know whether the charger is safe to use (depending on its listed amps and voltage).
For older devices using a 30-pin charge port, a connector can be used to control the Lightning Connector.
In order for a charger for use on another device, it’s important 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 so far as charging heads, while notebook chargers are often specific to both make and model. However, the plug fitting securely is just 1 part of this equation.
Somewhere on the power brick of the charger you’ll find 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 base of the charger, where it would meet up with 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 into the device, or how much is being”pushed” into 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 needed by the device. This is important: drawing too high a voltage could short out the device and possibly even begin a fire, while too low a voltage will fail to charge the battery.
Amperage is how fast power is”pulled” to the apparatus, or how much electricity is used by the device. The quantity of volts won’t ever change, but the amount of amps that the device pulls may change based on how hard the unit is working. The number that you locate on the battery that came with your device will be the maximum amount of amps which may be pulled by the device. 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 unit is paired with a charger which can’t support the amp necessity, it can burn out the power supply and kill the apparatus.
So if you 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 may not work with USB interfaces that employ the newest Battery Charging Specification.
If The Micro USB Charger’s Voltage Isn’t 5v…
Some devices may have their voltage recorded with 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 apparatus 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 all chargers provide a higher voltage than the batteries they charge. That is pretty much how they operate. There has to be a voltage differential to produce the necessary current flow in the proper direction to charge the battery. If you look at your car, it’s a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.
The problem with knockoffs, especially cheap knockoffs, is they frequently don’t support the energy needs of the device, or are not built to keep a steady flow safely. Overall, it’s best to stick with the charger designed for the device you are 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 come with your smart phone, laptop, camera, tablet, or other apparatus. Make sure you follow exactly what we said and you should be good to go!
