Can You Use Any Charger With Any Mobile Phone, Laptop, Camera, or Tablet?
Every mobile phone, notebook, and tablet seem to come with their own charger. If you are like me, you have probably compiled quite a few chargers over the years. So the question becomes: is it safe to use a charger with your phone, laptop, camera, or tablet computer that is not the original manufacturer’s charger which came with the device?
Types of Chargers
In this article, we will concentrate on three types of chargers: laptop chargers, micro USB chargers (these are used with phones, tablet computers, 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 fairly 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 the charger”head” and might not be the optimal charging amperage or voltage for your device.
Micro USBs are 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 different 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).
Apple Lightning Connectors are standard on all new Apple devices, including iPads and iPods. For older devices with a 30-pin charge interface, a connector can be used to control the Lightning Connector.
In order for a charger for use on a different 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 as far as charging heads, whilst notebook chargers are usually specific to both make and model. However, the plug fitting securely is only one part of the equation.
How Voltage and Amperage Matter
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 found at the bottom of the charger, where it would meet up with the wall. For the device you’re attempting to control, the voltage and amperage required will be seen on the battery that came with the device or on the manufacturer’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, 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” into the device, or how much electricity is used by the device. The quantity of volts will never change, but the quantity of amps that the device pulls may change depending on how hard the unit is working. The number that you find on the battery that came with your device are the maximum amount of amps which can be pulled by the device. In order to swap 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 which can’t support the amp requirement, it can 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 quicker charging (so long as the voltage is equivalent ). *Website Note: if you have an older device, it might not work with USB ports that use the new Battery Charging Specification.
If The Micro USB Charger’s Voltage Is Not 5v…
Some devices might have their voltage recorded 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 and 5 percent 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 higher than the device’s listed amperage).
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 needs to be a voltage differential to produce the necessary current flow in the proper way to charge the battery. When you look at your vehicle, it has a 12V battery, but typical alternators provide 13.8 to 14.4V charging voltage to the battery.
Stay Away From Cheap Knockoff Chargers
The issue with knockoffs, especially cheap knockoffs, is that they frequently don’t support the energy requirements of the apparatus, or aren’t built to maintain a steady flow safely. Overall, it’s best to stick with the charger made for the device you are using.
Now You Understand How to Safely & Effectively Swap Chargers
I hope this article was able to help 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 device. Make certain you follow exactly what we said and you should be ready to go!
