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 have probably compiled quite a few chargers over 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 which came with the device?
Kinds of Chargers
In this article, we will concentrate on three types of chargers: laptop 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 unique to the device they come with. However, there can be some generic chargers which boast the capability to be interchanged between notebooks. This always requires changing of the charger”head” and may not be the best charging amperage or voltage to your device.
Micro USBs are 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 various amps. I will explain this further later and how to know if 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 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 securely into 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 firmly is just one part of this equation.
Determined by the power brick of the charger you will get a label with the charger’s voltage (V) and amperage (A). For laptop chargers, this charging brick is often halfway down the charger and appears 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, where it would meet up with the wall. For the device you’re 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 how much is being”pushed” into the device by the charger. A phone will usually pull up to around 5V, while a notebook can pull up to 25V. A charger must equal the voltage required by the device. This is important: drawing too high a voltage could short out the device and potentially even start a fire, while too low a voltage will fail to charge the battery.
Amperage is how fast power is”pulled” to the apparatus, or how much power is used by the device. The amount 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 find on the battery that came with your device will be the max amount of amps that may be pulled by the device. The amount found on the charger is how many amps can be pulled at once. 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 if you have a modern USB device (smart phone, tablet, or camera) you can plug into a high-amperage USB port and enjoy faster 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 Isn’t 5v…
Some devices may have their voltage recorded using 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 apparatus 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 supply a higher voltage than the batteries that they charge. That’s pretty much how they operate. There needs to be a voltage differential to produce the necessary current flow in the correct way to charge the battery. When you look at your car, it has a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.
The issue with knockoffs, especially cheap knockoffs, is they frequently don’t support the power requirements of the device, or are not 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 best to stay 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 effectively use a charger that did not come with your smart phone, laptop, camera, tabletcomputer, or other apparatus. Be sure you follow exactly what we said and you should be good to go!
