Can You Use Any Charger With Any Mobile Phone, Notebook, Camera, or Tablet?
Every cell phone, notebook, and tablet appear to come with their own charger. If you’re like me, you’ve probably compiled a number of chargers over 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?
Types of Chargers
In this article, we will focus 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 with a slightly different head or charging cable, these are the most frequent.
Laptop chargers are rather specific to the device they come with. However, there may be some generic chargers that boast the capability to be interchanged between laptops. This always requires changing of the charger”head” and might not be the best charging amperage or voltage to 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 exact same voltage, but may draw various amps. I will explain this further later and how to know if 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 control the Lightning Connector.
In order for a charger to be used on a different device, it’s essential 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 so 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 the equation.
Somewhere on the power brick of the charger you’ll get a label with the charger’s voltage (V) and amperage (A). For notebook chargers, this charging brick is often halfway down the charger and typically looks exactly like it sounds — a brick. 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 charge, the voltage and amperage required will be found on the battery that came with the device or on the manufacturer’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 approximately 5V, while a notebook 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 possibly even begin a fire, while too low a voltage will fail to charge the battery.
Amperage is how fast power is”pulled” into the apparatus, 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 find on the battery that came with your device are the maximum amount of amps which may be pulled by the device. The number found on the charger is how many amps can be pulled simultaneously. If a device is paired with a charger that cannot support the amp necessity, 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 faster charging (as long as the voltage is equal). *Website Note: if you have an older device, it might not work with USB ports that employ 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 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 apparatus can take 5v minus 5 percent of 5v = 4.75 volts OR 5v plus 5% of 5v = 5.25 volts. So this means anything between 4.75 t0 5.25v is safe to use (so 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 is pretty much how they work. There has to be a voltage differential to generate the necessary current flow in the proper way to charge the battery. When you look at your car, it’s 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 they often don’t support the energy requirements of the apparatus, or are not built to keep a steady flow securely. This can cause damage to the device but can also pose a safety/fire hazard. Overall, it’s best to stay with the charger made for the device you’re 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. Be certain you follow what we said and you should be good to go!
