Can You Use Any Charger With Any Mobile Phone, Laptop, Camera, or Tablet?
Every cell phone, laptop, and tablet seem to come with their own charger. If you’re like me, you have 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 which came with the device?
Kinds of Chargers
In this guide, we’ll concentrate on three types of chargers: laptop chargers, micro USB chargers (these are used with telephones, tablets, and cameras), and Apple Lightning Connectors. While 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 can be some generic chargers that boast the capability to be interchanged between laptops. This always requires changing of the charger”head” and might not be the optimal charging amperage or voltage to 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 exact same voltage, but may draw various amps. I’ll 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 using a 30-pin charge port, a connector can be used to control the Lightning Connector.
For a charger for use on another device, it’s important 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 as far as charging heads, whilst laptop chargers are usually specific to both make and model. However, the plug fitting securely is only one part of this equation.
Somewhere on the power brick of the charger you will 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, where it would meet the wall. For the device you are trying 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” to the apparatus by the charger. A phone will usually pull up to around 5V, though a laptop can pull up to 25V. A charger must equal the voltage required by the device. This is important: drawing too high of a voltage could short out the device and possibly even start a fire, while too low a voltage will fail to charge the battery.
Amperage is how fast power is”pulled” into the apparatus, or how much power is used by the device. The quantity of volts won’t ever change, but the quantity of amps that the device pulls may change depending 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 by the device. The amount found on the charger is how many amps can be pulled simultaneously. 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 necessity, it may burn out the power supply 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 (so long as the voltage is equivalent ). *Site Note: if you have an older device, it may 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 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 device can take 5v minus 5 percent of 5v = 4.75 volts OR 5v plus 5 percent of 5v = 5.25 volts.
An interesting thing to note is chargers provide a higher voltage than the batteries they charge. That is pretty much how they operate. There has to be a voltage differential to generate the necessary current flow in the correct direction 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.
Stay Away From Cheap Knockoff Chargers
The problem with knockoffs, especially cheap knockoffs, is they frequently don’t support the power needs of the device, or are not built to keep a steady flow safely. Overall, it’s best to stick with the charger designed 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 efficiently use a charger that did not include your smart phone, laptop, camera, tabletcomputer, or other device. Make certain you follow what we said and you should be good to go!
