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 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 computer that is not 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 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 common.
Laptop chargers are rather unique to the device they include. However, there may be some generic chargers that boast the capability to be interchanged between notebooks. This always requires changing of the 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 apparatus, 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 recorded 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
In order 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 so far as charging heads, whilst notebook chargers are often specific to both make and model. However, the plug fitting securely is only one part of the equation.
Determined by the power brick of the charger you will find a tag with the charger’s voltage (V) and amperage (A). For other types of chargers, like a smartphone charger, this information is usually located at the base of the charger, where it would meet up with 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 company’s website.
Voltage is how much power the charger will draw into the device, or how much is being”pushed” to the device 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 needed by the device. This is important: drawing too high of a voltage could short out the device and potentially even begin 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 amount of volts won’t ever change, but the amount 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 are the max amount of amps that may be pulled from the device. To be able to exchange chargers, the amp number on the charger must equal or exceed the amp number recorded on the device’s battery. If a device is paired with a charger which can’t support the amp necessity, it can burn out the power source and kill the apparatus.
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 (so long as the voltage is equivalent ). *Site Note: if you have an older device, it may not work with USB ports that use the new 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 true, you may 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.
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 proper direction to charge the battery. When you look at your vehicle, 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 frequently don’t support the energy needs of the device, 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 stick with the charger made for the device you are 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 come with your smart phone, laptop, camera, tablet, or other device. Be certain to follow exactly what we said and you should be good to go!
