Can You Use Any Charger With Any Mobile Phone, Notebook, Camera, or Tablet?
Every mobile phone, laptop, and tablet seem to come with their own charger. If you are like me, you have probably compiled a number of chargers over 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?
Types of Chargers
In this guide, we’ll focus 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 with a slightly different head or charging cable, these are the most frequent.
Laptop chargers are fairly specific to the device they come with. However, there may be some generic chargers which boast the capability to be interchanged between notebooks. This always requires changing of the charger”head” and may not be the best charging amperage or voltage to your device.
Micro USBs are theoretically designed to be interchangeable, and are standard in many smartphones, Android devices, 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 (based on its listed amps and voltage).
For older devices using a 30-pin charge interface, a connector can be used to charge with the Lightning Connector.
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 as far as charging heads, whilst notebook chargers are usually specific to both make and model. However, the plug fitting firmly is only 1 part of this equation.
Determined by 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 base of the charger, in which it would meet 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 company’s website.
Voltage is how much power the charger will draw into the apparatus, or just how much is being”pushed” into 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 needed by the device.
Amperage is how quickly power is”pulled” to the device, or how much electricity is used by the device. The quantity of volts will never 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 will be the max amount of amps which 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 device is paired with a charger which can’t support the amp requirement, it may burn out the power source and kill the apparatus.
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 (as long as the voltage is equal). *Site Note: if you have an older device, it may not work with USB ports that employ the new Battery Charging Specification.
If The Micro USB Charger’s Voltage Is Not 5v…
Some devices may have their voltage recorded using a plus/minus on it like this: 5v +- 5%. If this is true, you may 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 percent of 5v = 4.75 volts OR 5v plus 5 percent of 5v = 5.25 volts.
An interesting point to note is all chargers supply a higher voltage than the batteries that they charge. That is pretty much how they work. There needs to be a voltage differential to generate the necessary current flow in the proper way 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.
Stay Away From Cheap Knockoff Chargers
The issue with knockoffs, especially cheap knockoffs, is they frequently don’t support the power needs of the device, or are not 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 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 include your smart phone, laptop, camera, tablet, or other device. Make sure to follow exactly what we said and you should be ready to go!
