Can You Use Any Charger With Any Mobile Phone, Notebook, Camera, or Tablet?
Every cell phone, notebook, and tablet appear to come with their own charger. If you are like me, you’ve probably compiled a number of chargers over the years. So the question becomes: is it safe to use a charger with your phone, notebook, camera, or tablet computer 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: laptop 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 rather specific 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 this charger”head” and might not be the optimal charging amperage or voltage for 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 different amps. I will explain this further later and how to know whether the charger is safe to use (depending on its listed amps and voltage).
For older devices using a 30-pin charge port, a connector can be used to control the Lightning Connector.
The Plugs Must Be The Same
For a charger to be used on another device, it’s essential 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 so 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 this equation.
How Voltage and Amperage Matter
Somewhere on the power brick of the charger you’ll get a label with the charger’s voltage (V) and amperage (A). For notebook chargers, this charging brick is often halfway down the charger and typically looks exactly like it sounds — a brick. For other types of chargers, like a smartphone charger, this information is usually located at the base of the charger, where it would meet the wall. For the device you’re attempting to control, 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 in the apparatus, or how much is being”pushed” into the device 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 required by the device.
Amperage is how fast power is”pulled” into the device, or how much electricity is used by the device. The amount 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 find on the battery that came with your device are the maximum 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. In order to exchange chargers, the amp number on the charger must equal or exceed the amp number listed on the device’s battery. If a unit is paired with a charger which can’t support the amp requirement, it can burn out the power supply and kill the device.
So if you 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 equal). *Website Note: if you have an older device, it might not work with USB interfaces that use the new Battery Charging Specification.
If The Micro USB Charger’s Voltage Isn’t 5v…
Some devices may have their voltage listed using a plus/minus on it like that: 5v +- 5%. If this is the case, 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 plus 5 percent of 5v = 5.25 volts. This means anything between 4.75 t0 5.25v is safe to use (as long as the amperage of the charger is equivalent to or greater than the device’s listed amperage).
An interesting thing to note is all chargers provide a higher voltage than the batteries they charge. That is pretty much how they work. There needs to be a voltage differential to produce the necessary current flow in the proper way 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 issue with knockoffs, especially cheap knockoffs, is they frequently don’t support the energy needs of the apparatus, or are not 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 better to stick with the charger designed 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 apparatus. Make sure you follow exactly what we said and you should be ready to go!
