Can You Use Any Charger With Any Mobile Phone, Laptop, Camera, or Tablet?
Every cell 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 which came with the device?
Kinds of Chargers
In this guide, we’ll concentrate on three types of chargers: laptop chargers, micro USB chargers (these are used with phones, tablets, and cameras), and Apple Lightning Connectors. While some devices have chargers with a slightly different head or charging cable, these are the most frequent.
Laptop chargers are fairly unique 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 may not be the optimal charging amperage or voltage to 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 exact same voltage, but may draw different amps. I will explain this further later and how to know whether the charger is safe to use (based on its recorded amps and voltage).
Apple Lightning Connectors are standard on all new Apple devices, such as iPads and iPods. For older devices with a 30-pin charge interface, a connector can be used to control the Lightning Connector.
The Plugs Must Be The Same
In order 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 unit. Micro USBs are the same across the board as far as charging heads, while notebook chargers are usually specific to both make and model. However, the plug fitting securely is just 1 part of the equation.
Determined by the power brick of the charger you’ll 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 found at the base of the charger, in which it would meet up with 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 in the apparatus, or just how much is being”pushed” to the apparatus 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.
Amperage is how fast power is”pulled” to the device, 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 depending on how hard the device is working. The number that you locate on the battery that came with your device are the max amount of amps that may be pulled from the device. 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 may burn out the power source and kill the apparatus.
So for those who have a modern USB device (smart phone, tablet, or camera) you can plug into a high-amperage USB port and enjoy faster charging (as long as the voltage is equivalent ). *Site Note: if you have an older device, it may not work with USB ports that use the newest Battery Charging Specification.
If The Micro USB Charger’s Voltage Is Not 5v…
Some devices may have their voltage recorded with a plus/minus on it like that: 5v +- 5%. If this is the case, you may 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 percent of 5v = 4.75 volts OR 5v and 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 equivalent to or higher than the device’s listed amperage).
An interesting point to note is all chargers supply a higher voltage than the batteries they charge. That’s pretty much how they work. There needs to be a voltage differential to produce the necessary current flow in the correct 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 issue with knockoffs, especially cheap knockoffs, is that they frequently don’t support the power requirements of the apparatus, or aren’t built to maintain a steady flow securely. Overall, it’s best to stick with the charger designed 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 effectively use a charger that did not come with your smart phone, laptop, camera, tabletcomputer, or other apparatus. Be sure to follow what we said and you should be ready to go!
