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 are 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 that isn’t the original manufacturer’s charger that came with the device?
Kinds of Chargers
In this article, we will focus 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 common.
Laptop chargers are fairly specific to the device they come with. However, there may be some generic chargers which 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 designed to be interchangeable, and are standard in most smartphones, Android devices, and tablets. Micro USB chargers typically have the same voltage, but may draw various amps. I will explain this further later and how to know if the charger is safe to use (based on its listed 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.
In order for a charger for use on a different 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 laptop chargers are usually specific to both make and model. However, the plug fitting securely is only 1 part of this equation.
Determined by the power brick of the charger you’ll find a label with the charger’s voltage (V) and amperage (A). For laptop 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 found at the bottom of the charger, in which it would meet up with the wall. For the device you’re trying 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 in the apparatus, or just how much is being”pushed” into the apparatus 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 quickly power is”pulled” to 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 system 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 which can be pulled from the device. In order to swap chargers, the amp number on the charger must equal or exceed the amp number recorded on the device’s battery. If a unit is paired with a charger that cannot support the amp necessity, it may burn out the power source and kill the device.
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 might not work with USB interfaces that employ 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 score 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. So 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 point to note is chargers supply a higher voltage than the batteries that 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. When you look at your car, it has 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 often don’t support the energy requirements of the device, or are not built to keep 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 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 come with your smart phone, laptop, camera, tablet, or other apparatus. Be sure to follow what we said and you should be good to go!
