Can You Use Any Charger With Any Mobile Phone, Notebook, Camera, or Tablet?
Every mobile phone, laptop, and tablet appear to come with their own charger. If you’re like me, you’ve probably compiled quite a few chargers through the years. So the question becomes: is it safe to use a charger with your phone, notebook, camera, or tablet computer that is not the original manufacturer’s charger which came with the device?
Kinds of Chargers
In this article, 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 using a slightly different head or charging cable, these are the most common.
Laptop chargers are rather specific to the device they come with. 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 might 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 exact same voltage, but may draw various amps. I’ll explain this further later and how to know whether 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 charge with the Lightning Connector.
For a charger for use on a different 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 often specific to both make and model. However, the plug fitting securely is just 1 part of this equation.
Somewhere on the power brick of the charger you’ll find a label with the charger’s voltage (V) and amperage (A). For laptop chargers, this charging brick is often halfway down the charger and appears exactly like it sounds — a brick. 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 are 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 into the device, or how much is being”pushed” to the apparatus by the charger. A phone will usually pull up to around 5V, while a laptop 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 start a fire, while too low a voltage will fail to charge the battery.
Amperage is how fast power is”pulled” into the device, or how much power is used by the device. The amount of volts won’t ever change, but the quantity of amps that the device pulls may change based on how hard the device is working. The number that you locate on the battery that came with your device are the maximum amount of amps which can be pulled from the device. If a device is paired with a charger that cannot support the amp necessity, 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 quicker charging (so long as the voltage is equivalent ). *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 may 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 rating 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. 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 greater than the device’s listed amperage).
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 needs to be a voltage differential to produce the necessary current flow in the correct way to charge the battery. If you look at your car, it’s a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.
The problem with knockoffs, especially cheap knockoffs, is they frequently don’t support the energy requirements of the apparatus, or are not built to keep a steady flow safely. This can result in damage to the device but can also pose a safety/fire hazard. Overall, it’s better 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 assist you. Now you know how to safely and efficiently use a charger that did not include your smart phone, notebook, camera, tablet, or other device. Be sure you follow exactly what we said and you should be ready to go!
