Can You Use Any Charger With Any Mobile Phone, Notebook, Camera, or Tablet?
Every mobile phone, laptop, and tablet appear to come with their own charger. If you’re 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, notebook, camera, or tablet that isn’t the original manufacturer’s charger which came with the device?
Types of Chargers
In this guide, we’ll concentrate 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 common.
Laptop chargers are fairly specific to the device they include. However, there can be some generic chargers that boast the capability to be interchanged between notebooks. 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 devices, 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 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 charge with the Lightning Connector.
In order for a charger to be used on another 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, whilst laptop chargers are usually specific to both make and model. However, the plug fitting securely is only one part of this equation.
Determined by the power brick of the charger you will get a label 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 bottom of the charger, in which it would meet the wall. For the device you are 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 device, or just how much is being”pushed” to the device 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 required by the device. This is important: drawing too high of 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” 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 unit is working. The number that you find on the battery that came with your device will be the max amount of amps that may 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 unit is paired with a charger that cannot support the amp necessity, it may burn out the power supply 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 quicker charging (so long as the voltage is equivalent ). *Site Note: if you have an older device, it may not work with USB interfaces that use the newest Battery Charging Specification.
If The Micro USB Charger’s Voltage Is Not 5v…
Some devices might have their voltage listed using a plus/minus on it like that: 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 percent of 5v = 5.25 volts.
An interesting thing 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 generate the necessary current flow in the correct direction to charge the battery. When you look at your vehicle, 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 often don’t support the energy needs of the device, or aren’t built to maintain a steady flow securely. Overall, it’s best to stay 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 efficiently use a charger that did not include your smart phone, notebook, camera, tabletcomputer, or other apparatus. Make sure you follow exactly what we said and you should be good to go!
