Can You Use Any Charger With Any Cell Phone, Notebook, Camera, or Tablet?
Every cell phone, notebook, and tablet seem to come with their own charger. If you’re 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, notebook, camera, or tablet that isn’t the original manufacturer’s charger which came with the device?
Kinds of Chargers
In this guide, we’ll focus on three types of chargers: notebook chargers, micro USB chargers (these are used with phones, tablets, and cameras), and Apple Lightning Connectors. While some devices have chargers with a slightly different head or charging cable, these are the most common.
Laptop chargers are fairly unique to the device they come with. However, there may be some generic chargers which boast the ability to be interchanged between laptops. This always requires changing of the charger”head” and might not be the optimal charging amperage or voltage for your device.
Micro USBs are designed to be interchangeable, and are standard in most smartphones, Android apparatus, and tablets. Micro USB chargers typically have the same voltage, but may draw different amps. I’ll explain this further later and how to know whether the charger is safe to use (based on its recorded amps and voltage).
For older devices using a 30-pin charge port, a connector can be used to control the Lightning Connector.
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 laptop chargers are usually specific to both make and model. However, the plug fitting firmly is only 1 part of this equation.
Determined by the power brick of the charger you will 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 located at the base of the charger, where it would meet up with the wall. For the device you are trying to control, the voltage and amperage required will be seen 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 apparatus, or just how much is being”pushed” to the apparatus by the charger. A phone will usually pull up to approximately 5V, though a notebook can pull up to 25V. A charger must equal the voltage needed by the device.
Amperage is how quickly power is”pulled” to the apparatus, or how much electricity is used by the device. The amount of volts will never change, but the quantity of amps that the system pulls may change depending on how hard the unit 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. The number found on the charger is how many amps can be pulled at once. 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 for those who have a modern USB device (smart phone, tabletcomputer, or camera) you can plug into a high-amperage USB port and enjoy quicker charging (as 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 may 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.
An interesting point to note is all chargers provide a higher voltage than the batteries that they charge. That’s pretty much how they operate. There needs to be a voltage differential to generate the necessary current flow in the correct way to charge the battery. When you look at your vehicle, 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 issue with knockoffs, particularly cheap knockoffs, is that they often don’t support the power needs of the apparatus, or are not built to maintain a steady flow safely. 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 assist you. Now you know how to safely and efficiently use a charger that did not include your smart phone, laptop, camera, tabletcomputer, or other device. Be certain to follow exactly what we said and you should be ready to go!
