Can You Use Any Charger With Any Cell Phone, Laptop, Camera, or Tablet?
Every mobile phone, notebook, and tablet appear 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, laptop, camera, or tablet that is not the original manufacturer’s charger that came with the device?
Types of Chargers
In this guide, we will concentrate on three types of chargers: laptop chargers, micro USB chargers (these are used with telephones, tablets, and cameras), and Apple Lightning Connectors. While some devices have chargers using 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 notebooks. This always requires changing of the 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 most smartphones, Android devices, 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 (based 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.
For a charger for use on a different 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, while laptop chargers are usually 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 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 trying 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 just how much is being”pushed” to the device by the charger. A phone will usually pull up to approximately 5V, while a laptop can pull up to 25V. A charger must equal the voltage required by the device. This is important: drawing too high a voltage could short out the device and potentially even begin a fire, while too low a voltage will fail to charge the battery.
Amperage is how fast 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 amount 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 may be pulled by the device. If a device is paired with a charger which can’t support the amp necessity, it may burn out the power source and kill the device.
So for those who 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 equivalent ). *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 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 score is telling you is that the device can take 5v minus 5% of 5v = 4.75 volts OR 5v and 5 percent of 5v = 5.25 volts.
An interesting thing to note is chargers supply a higher voltage than the batteries they charge. That’s pretty much how they operate. There has 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 typical alternators provide 13.8 to 14.4V charging voltage to the battery.
The issue with knockoffs, especially cheap knockoffs, is they often don’t support the energy requirements of the apparatus, or are not built to keep a steady flow securely. Overall, it’s better to stay 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 assist you. Now you know how to safely and effectively use a charger that did not come with your smart phone, notebook, camera, tabletcomputer, or other apparatus. Make sure to follow exactly what we said and you should be ready to go!
