Can You Use Any Charger With Any Mobile Phone, Notebook, Camera, or Tablet?
Every mobile phone, notebook, and tablet appear to come with their own charger. If you’re like me, you have probably compiled a number of chargers over the years. So the question becomes: is it safe to use a charger with your phone, laptop, camera, or tablet that isn’t the original manufacturer’s charger which came with the device?
Types of Chargers
In this guide, we will focus on three types of chargers: notebook chargers, micro USB chargers (these are used with telephones, tablets, 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 unique to the device they include. However, there can be some generic chargers which 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 for your device.
Micro USBs are theoretically 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 various 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 using a 30-pin charge interface, a connector can be used to charge with the Lightning Connector.
The Plugs Must Be The Same
For a charger to be used on a different device, it’s essential 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 so far as charging heads, while laptop chargers are usually specific to both make and model. However, the plug fitting firmly is only one 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 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 into the apparatus, or how much is being”pushed” to 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” to the device, or how much power is used by the device. The amount 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 are the max amount of amps that can be pulled from 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 listed 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 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 (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 newest Battery Charging Specification.
If The Micro USB Charger’s Voltage Isn’t 5v…
Some devices may 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 device can take 5v minus 5 percent of 5v = 4.75 volts OR 5v plus 5% of 5v = 5.25 volts. This means anything between 4.75 t0 5.25v is safe to use (as long as the amperage of the charger is equal to or greater than the device’s listed amperage).
An interesting point to note is chargers provide a higher voltage than the batteries they charge. That’s pretty much how they work. There has to be a voltage differential to generate the necessary current flow in the proper direction to charge the battery. If you look at your vehicle, 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 power needs of the apparatus, or aren’t built to keep a steady flow securely. Overall, it’s better 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 effectively use a charger that did not come with your smart phone, laptop, camera, tablet, or other apparatus. Be sure to follow what we said and you should be good to go!
