Can You Use Any Charger With Any Mobile Phone, Notebook, Camera, or Tablet?
Every mobile phone, notebook, and tablet seem to come with their own charger. If you’re 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, notebook, camera, or tablet that is not the original manufacturer’s charger that came with the device?
Kinds of Chargers
In this article, we’ll concentrate on three types of chargers: notebook chargers, micro USB chargers (these are used with telephones, tablets, and cameras), and Apple Lightning Connectors. While some devices have chargers with a slightly different head or charging cable, these are the most frequent.
Laptop chargers are fairly specific to the device they come with. However, there can be some generic chargers which boast the capability to be interchanged between laptops. This always requires changing of the 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 many smartphones, Android devices, and tablets. Micro USB chargers typically have the exact same voltage, but may draw different amps. I’ll explain this further later and how to know if the charger is safe to use (based on its recorded amps and voltage).
Apple Lightning Connectors are standard on all new Apple devices, including iPads and iPods. For older devices with a 30-pin charge port, a connector can be used to charge with the Lightning Connector.
In order for a charger to be used 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 as far as charging heads, whilst notebook chargers are usually specific to both make and model. However, the plug fitting securely is just 1 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 found at the bottom 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 in the device, or just how much is being”pushed” to the device 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.
Amperage is how fast power is”pulled” to the device, or how much power is used by the device. The quantity of volts will never change, but the amount of amps that the device pulls may change depending on how hard the unit 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 by the device. The amount found on the charger is how many amps can be pulled at once. In order 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 that cannot support the amp necessity, it may 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 use the new Battery Charging Specification.
If The Micro USB Charger’s Voltage Isn’t 5v…
Some devices might have their voltage recorded using a plus/minus on it like this: 5v +- 5%. If this is the case, you may use a charger rated at 4.75 to 5.25v because that rating 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. So 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 higher than the device’s listed amperage).
An interesting thing to note is all chargers supply a higher voltage than the batteries that they charge. That is pretty much how they work. There has to be a voltage differential to produce the necessary current flow in the proper direction to charge the battery. If 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 problem with knockoffs, especially cheap knockoffs, is they often don’t support the energy requirements of the apparatus, or aren’t built to maintain a steady flow safely. This can cause damage to the device but can also pose a safety/fire hazard. Overall, it’s better to stay 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 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 you follow exactly what we said and you should be good to go!
