Can You Use Any Charger With Any Mobile Phone, Notebook, Camera, or Tablet?
Every cell phone, notebook, and tablet seem to come with their own charger. If you are like me, you have probably compiled quite a few 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 which came with the device?
Types of Chargers
In this article, we will concentrate on three types of chargers: notebook chargers, micro USB chargers (these are used with phones, tablets, and cameras), and Apple Lightning Connectors. While 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 which boast the ability to be interchanged between notebooks. This always requires changing of this charger”head” and may 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 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 for use on another device, it’s important 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 securely is just one part of the equation.
How Voltage and Amperage Matter
Determined by the power brick of the charger you’ll find a tag with the charger’s voltage (V) and amperage (A). For laptop 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 located at the base of the charger, in which it would meet up with the wall. For the device you are 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 device, or just how much is being”pushed” to the apparatus by the charger. A phone will usually pull up to around 5V, while a notebook can pull up to 25V. A charger must equal the voltage needed by the device. This is important: drawing too high 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 power is used by the device. The quantity of volts will never change, but the quantity 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 maximum amount of amps which may be pulled from the device. If a device is paired with a charger that cannot support the amp requirement, it may burn out the power supply and kill the apparatus.
So if you have a modern USB device (smart phone, tablet, 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 interfaces that use 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 that: 5v +- 5%. If this is true, 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 chargers provide a higher voltage than the batteries that 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 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 issue with knockoffs, especially cheap knockoffs, is that they frequently don’t support the power needs of the device, or are not built to keep a steady flow securely. Overall, it’s best to stick 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 assist you. Now you know how to safely and efficiently use a charger that did not come with your smart phone, notebook, camera, tabletcomputer, or other device. Be sure you follow exactly what we said and you should be good to go!
