Can You Use Any Charger With Any Mobile Phone, Laptop, 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 over 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?
Kinds of Chargers
In this guide, we’ll concentrate on three types of chargers: notebook 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 rather specific to the device they come with. 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 may not be the best charging amperage or voltage to your device.
Micro USBs are theoretically designed to be interchangeable, and are standard in most smartphones, Android apparatus, and tablets. Micro USB chargers typically have the same voltage, but may draw different 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).
Apple Lightning Connectors are standard on all new Apple devices, such as iPads and iPods. For older devices with a 30-pin charge interface, a connector can be used to charge with the Lightning Connector.
The Plugs Must Be The Same
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 device. Micro USBs are the same across the board as far as charging heads, while laptop chargers are often specific to both make and model. However, the plug fitting securely is only 1 part of this equation.
How Voltage and Amperage Matter
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 located at the base of the charger, where it would meet up with the wall. For the device you’re trying to charge, the voltage and amperage required will be seen 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 device 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 fast power is”pulled” to the device, or how much electricity is used by the device. The quantity of volts will never change, but the quantity of amps that the device 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 maximum amount of amps which may be pulled from the device. If a device is paired with a charger which can’t support the amp requirement, it can burn out the power supply and kill the apparatus.
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 faster charging (as long as the voltage is equivalent ). *Site Note: if you have an older device, it might not work with USB ports that employ the newest Battery Charging Specification.
If The Micro USB Charger’s Voltage Isn’t 5v…
Some devices might have their voltage listed 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 rating is telling you is that the device 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 generate the necessary current flow in the correct direction to charge the battery. If you look at your vehicle, it’s 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 that they often don’t support the power needs of the apparatus, or aren’t built to maintain 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 help 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. Be certain you follow exactly what we said and you should be good to go!
