Can You Use Any Charger With Any Cell Phone, Notebook, Camera, or Tablet?
Every mobile phone, notebook, and tablet seem 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, notebook, camera, or tablet that isn’t the original manufacturer’s charger which came with the device?
Types of Chargers
In this guide, we’ll focus on three types of chargers: laptop chargers, micro USB chargers (these are used with phones, tablet computers, 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 may be some generic chargers which boast the ability to be interchanged between notebooks. This always requires changing of this 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 same voltage, but may draw various amps. I will explain this further later and how to know if the charger is safe to use (depending on its recorded amps and voltage).
For older devices with a 30-pin charge interface, 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 notebook chargers are often specific to both make and model. However, the plug fitting securely is just 1 part of the equation.
Determined by the power brick of the charger you will find a tag with the charger’s voltage (V) and amperage (A). For notebook 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 attempting to charge, 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 in the device, or how much is being”pushed” to 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 needed by the device. This is important: drawing too high a voltage could short out the device and potentially even begin a fire, while too low a voltage will fail to charge the battery.
Amperage is how fast 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 quantity of amps that the system pulls may change based on how hard the device is working. The number that you locate on the battery that came with your device will be the max amount of amps which can be pulled from the device. The number found on the charger is how many amps can be pulled at once. To be able to swap chargers, the amp number on the charger must equal or exceed the amp number listed on the device’s battery. If a device is paired with a charger which can’t support the amp necessity, it can burn out the power source 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 (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 newest Battery Charging Specification.
If The Micro USB Charger’s Voltage Is Not 5v…
Some devices might have their voltage listed 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 score is telling you is that the apparatus can take 5v minus 5% of 5v = 4.75 volts OR 5v and 5 percent of 5v = 5.25 volts.
An interesting thing to note is chargers provide a higher voltage than the batteries they charge. That’s pretty much how they work. There needs to be a voltage differential to produce the necessary current flow in the proper direction to charge the battery. If you look at your vehicle, it’s a 12V battery, but typical 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 energy needs of the device, 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 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 sure you follow what we said and you should be good to go!
