Can You Use Any Charger With Any Mobile Phone, Laptop, Camera, or Tablet?
Every cell phone, notebook, and tablet seem to come with their own charger. If you are 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, laptop, camera, or tablet computer that isn’t the original manufacturer’s charger that 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, 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 specific to the device they include. However, there may be some generic chargers that boast the ability to be interchanged between notebooks. This always requires changing of the 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 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).
Apple Lightning Connectors are standard on all new Apple devices, including iPads and iPods. For older devices using a 30-pin charge interface, a connector can be used to charge with the Lightning Connector.
For a charger to be used on a different device, it’s essential 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 usually specific to both make and model. However, the plug fitting firmly is just 1 part of the equation.
How Voltage and Amperage Matter
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 located at the base of the charger, in which it would meet the wall. For the device you’re attempting 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 how much is being”pushed” into the apparatus by the charger. A phone will usually pull up to around 5V, though a notebook can pull up to 25V. A charger must equal the voltage required by the device.
Amperage is how quickly power is”pulled” to the apparatus, or how much power is used by the device. The amount of volts won’t ever change, but the amount of amps that the device 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 maximum amount of amps that may be pulled by the device. The number found on the charger is how many amps can be pulled at once. In order 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 that cannot support the amp necessity, it can burn out the power supply and kill the device.
So if you 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 ). *Website Note: if you have an older device, it might not work with USB ports that use the new Battery Charging Specification.
If The Micro USB Charger’s Voltage Isn’t 5v…
Some devices might have their voltage recorded with a plus/minus on it like that: 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 apparatus can take 5v minus 5 percent of 5v = 4.75 volts OR 5v and 5 percent of 5v = 5.25 volts.
An interesting thing to note is chargers supply a higher voltage than the batteries they charge. That’s pretty much how they work. There needs to be a voltage differential to generate the necessary current flow in the proper way 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.
Stay Away From Cheap Knockoff Chargers
The problem with knockoffs, particularly cheap knockoffs, is they frequently don’t support the power requirements of the device, or aren’t built to keep a steady flow safely. This can result in damage to the device but can also pose a safety/fire hazard. Overall, it’s better to stay 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, notebook, camera, tablet, or other device. Make sure to follow exactly what we said and you should be good to go!
