Can You Use Any Charger With Any Cell Phone, Notebook, Camera, or Tablet?
Every cell phone, notebook, and tablet seem 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, notebook, camera, or tablet that is not the original manufacturer’s charger that 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 telephones, tablets, and cameras), and Apple Lightning Connectors. Although some devices have chargers using a slightly different head or charging cable, these are the most frequent.
Laptop chargers are rather specific to the device they include. 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 optimal charging amperage or voltage for your device.
Micro USBs are theoretically 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 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 using a 30-pin charge port, a connector can be used to charge with the Lightning Connector.
The Plugs Must Be The Same
In order for a charger for use on another device, it’s important that the plug of the charger (the”head”) fit snugly to the charging port of the unit. Micro USBs are the same across the board so far as charging heads, while laptop chargers are usually specific to both make and model. However, the plug fitting securely is only 1 part of this equation.
Somewhere on the power brick of the charger you will 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 bottom of the charger, where it would meet up with 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 approximately 5V, though a laptop can pull up to 25V. A charger must equal the voltage required 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 won’t ever change, but the quantity of amps that the system pulls may change depending on how hard the device is working. The number that you locate on the battery that came with your device are the max amount of amps that can be pulled by the device. If a device is paired with a charger which can’t support the amp requirement, it can 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 quicker charging (so long as the voltage is equal). *Website 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 might have their voltage listed using 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 score is telling you is that the device can take 5v minus 5 percent of 5v = 4.75 volts OR 5v plus 5% 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 equivalent to or greater than the device’s listed amperage).
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 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.
The issue with knockoffs, especially cheap knockoffs, is they frequently don’t support the energy requirements of the apparatus, or are not built to maintain a steady flow safely. Overall, it’s best to stay 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, laptop, camera, tabletcomputer, or other apparatus. Be sure you follow exactly what we said and you should be good to go!
