Can You Use Any Charger With Any Mobile Phone, Notebook, Camera, or Tablet?
Every mobile phone, notebook, and tablet appear to come with their own charger. If you’re like me, you’ve probably compiled a number of chargers through 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’ll concentrate on three types of chargers: notebook chargers, micro USB chargers (these are used with phones, tablets, and cameras), and Apple Lightning Connectors. Although some devices have chargers with a slightly different head or charging cable, these are the most frequent.
Laptop chargers are fairly unique to the device they include. However, there can be some generic chargers that boast the ability to be interchanged between notebooks. This always requires changing of the charger”head” and might 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 exact same voltage, but may draw various amps. I’ll explain this further later and how to know if the charger is safe to use (depending on its listed 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 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 unit. Micro USBs are the same across the board so far as charging heads, while laptop chargers are usually specific to both make and model. However, the plug fitting firmly is just one part of this equation.
Somewhere on the power brick of the charger you’ll 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’re 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 apparatus, or how much is being”pushed” to the apparatus by the charger. A phone will usually pull up to around 5V, though a notebook 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 system pulls may change based 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 that 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 for those who 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 ). *Site Note: if you have an older device, it may not work with USB ports that use the newest Battery Charging Specification.
If The Micro USB Charger’s Voltage Isn’t 5v…
Some devices might have their voltage recorded with a plus/minus on it like this: 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 device can take 5v minus 5% of 5v = 4.75 volts OR 5v and 5% of 5v = 5.25 volts.
An interesting thing to note is all chargers provide a higher voltage than the batteries they charge. That’s pretty much how they operate. 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 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, particularly cheap knockoffs, is that they often don’t support the power requirements of the device, or aren’t built to maintain 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 stay 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 assist you. Now you know how to safely and effectively use a charger that did not come with your smart phone, laptop, camera, tabletcomputer, or other apparatus. Be certain to follow what we said and you should be good to go!
