Can You Use Any Charger With Any Mobile Phone, Laptop, Camera, or Tablet?
Every mobile phone, notebook, and tablet appear to come with their own charger. If you are like me, you have probably compiled quite a few chargers over the years. So the question becomes: is it safe to use a charger with your phone, laptop, camera, or tablet computer that is not the original manufacturer’s charger which came with the device?
Kinds of Chargers
In this article, we will concentrate on three types of chargers: laptop chargers, micro USB chargers (these are used with phones, tablet computers, 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 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 may not be the best charging amperage or voltage for your device.
Micro USBs are theoretically designed to be interchangeable, and are standard in most smartphones, Android devices, and tablets. Micro USB chargers typically have the same voltage, but may draw various amps. I’ll explain this further later and how to know if the charger is safe to use (based on its listed amps and voltage).
Apple Lightning Connectors are standard on all new Apple devices, such as iPads and iPods. For older devices with a 30-pin charge port, a connector can be used to control the Lightning Connector.
The Plugs Must Be The Same
For a charger for use on a different device, it’s important that the plug of the charger (the”head”) fit snugly to the charging port of the device. Micro USBs are the same across the board so far as charging heads, while laptop chargers are often specific to both make and model. However, the plug fitting firmly is just 1 part of this equation.
Determined by the power brick of the charger you’ll get 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 up with the wall. For the device you’re attempting 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 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 required by the device. This is important: drawing too high a voltage could short out the device and potentially even start a fire, while too low a voltage will fail to charge the battery.
Amperage is how quickly power is”pulled” into the device, or how much electricity is used by the device. The quantity of volts will never change, but the quantity of amps that the system pulls may change based on how hard the device is working. The number that you find on the battery that came with your device are the max amount of amps which can be pulled by the device. If a device is paired with a charger that cannot support the amp requirement, it can 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 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 with 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% of 5v = 4.75 volts OR 5v and 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 equal to or greater than the device’s listed amperage).
An interesting point to note is all chargers provide a higher voltage than the batteries they charge. That is pretty much how they operate. There has to be a voltage differential to generate the necessary current flow in the correct direction to charge the battery. When you look at your car, it’s 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, especially cheap knockoffs, is they often don’t support the power requirements of the device, 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’re using.
Now You Know 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. Make sure to follow what we said and you should be ready to go!
