Can You Use Any Charger With Any Cell 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, notebook, camera, or tablet that is not the original manufacturer’s charger which 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, 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 specific to the device they come with. However, there can be some generic chargers which boast the ability to be interchanged between laptops. This always requires changing of the charger”head” and might not be the optimal charging amperage or voltage for your device.
Micro USBs are theoretically designed to be interchangeable, and are standard in most smartphones, Android apparatus, 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 if the charger is safe to use (based on its listed 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 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 so far as charging heads, whilst notebook chargers are usually specific to both make and model. However, the plug fitting firmly is only one part of this equation.
Determined by the power brick of the charger you will 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 base of the charger, where it would meet up with the wall. For the device you’re trying to charge, 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 into the apparatus, or just how much is being”pushed” into the apparatus by the charger. A phone will usually pull up to around 5V, though a laptop can pull up to 25V. A charger must equal the voltage needed by the device.
Amperage is how quickly power is”pulled” into the apparatus, or how much power is used by the device. The quantity of volts won’t ever change, but the quantity of amps that the system 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 maximum amount of amps that can be pulled from the device. To be able to exchange chargers, the amp number on the charger must equal or exceed the amp number listed on the device’s battery. If a unit is paired with a charger that cannot support the amp requirement, it may 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 (so long as the voltage is equivalent ). *Site Note: if you have an older device, it may not work with USB ports that use the new Battery Charging Specification.
If The Micro USB Charger’s Voltage Is Not 5v…
Some devices may have their voltage listed with a plus/minus on it like this: 5v +- 5%. If this is the case, 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 percent of 5v = 4.75 volts OR 5v plus 5% of 5v = 5.25 volts.
An interesting point to note is all chargers supply a higher voltage than the batteries that they charge. That’s pretty much how they work. There needs to be a voltage differential to generate the necessary current flow in the correct way 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.
Stay Away From Cheap Knockoff Chargers
The problem with knockoffs, especially cheap knockoffs, is they frequently don’t support the energy requirements of the device, or aren’t built to maintain a steady flow safely. Overall, it’s better to stay with the charger designed 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 apparatus. Be certain to follow exactly what we said and you should be ready to go!
