Can You Use Any Charger With Any Cell Phone, Notebook, Camera, or Tablet?
Every cell phone, laptop, and tablet appear to come with their own charger. If you are like me, you’ve probably compiled a number of chargers through the years. So the question becomes: is it safe to use a charger with your phone, laptop, camera, or tablet that isn’t the original manufacturer’s charger that came with the device?
Types of Chargers
In this guide, we will focus on three types of chargers: notebook chargers, micro USB chargers (these are used with telephones, tablet computers, and cameras), and Apple Lightning Connectors. While some devices have chargers with 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 ability to be interchanged between notebooks. This always requires changing of the charger”head” and may not be the optimal charging amperage or voltage for your device.
Micro USBs are designed to be interchangeable, and are standard in many smartphones, Android apparatus, and tablets. Micro USB chargers typically have the same voltage, but may draw various amps. I will explain this further later and how to know if the charger is safe to use (depending on its listed amps and voltage).
For older devices using a 30-pin charge port, a connector can be used to control the Lightning Connector.
For a charger to be used on a different device, it’s important that the plug of the charger (the”head”) fit securely into the charging port of the unit. Micro USBs are the same across the board as 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.
How Voltage and Amperage Matter
Determined by the power brick of the charger you will find 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 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 in the device, or how much is being”pushed” to the apparatus by the charger. A phone will usually pull up to approximately 5V, while 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 apparatus, or how much electricity is used by the device. The amount of volts will never change, but the amount of amps that the device pulls may change based on how hard the unit is working. The number that you locate on the battery that came with your device will be the maximum amount of amps which may be pulled by the device. If a unit is paired with a charger which can’t support the amp necessity, it may burn out the power source and kill the device.
So if you 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 ). *Site Note: if you have an older device, it may not work with USB ports that employ the newest 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 this: 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 device can take 5v minus 5% of 5v = 4.75 volts OR 5v and 5 percent of 5v = 5.25 volts.
An interesting point to note is chargers supply a higher voltage than the batteries they charge. That’s pretty much how they work. There has to be a voltage differential to produce the necessary current flow in the proper way to charge the battery. If you look at your vehicle, it has a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.
Stay Away From Cheap Knockoff Chargers
The problem with knockoffs, particularly cheap knockoffs, is that they frequently don’t support the energy needs of the apparatus, or aren’t built to keep a steady flow securely. This can result in damage to the device but can also pose a safety/fire hazard. 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 include your smart phone, notebook, camera, tablet, or other device. Be sure you follow what we said and you should be good to go!
