Can You Use Any Charger With Any Cell Phone, Notebook, Camera, or Tablet?
Every mobile phone, laptop, and tablet appear to come with their own charger. If you’re like me, you’ve 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’ll concentrate on three types of chargers: laptop chargers, micro USB chargers (these are used with phones, tablet computers, and cameras), and Apple Lightning Connectors. While some devices have chargers with a slightly different head or charging cable, these are the most common.
Laptop chargers are rather specific 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 this charger”head” and might 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 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 whether the charger is safe to use (depending on its listed amps and voltage).
For older devices using a 30-pin charge interface, a connector can be used to control the Lightning Connector.
The Plugs Must Be The Same
For a charger for use 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 as 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 this equation.
Determined by the power brick of the charger you will get a tag with the charger’s voltage (V) and amperage (A). For other types of chargers, like a smartphone charger, this information is usually found at the bottom of the charger, in which it would meet up with the wall. For the device you are trying to control, 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 device, or how much is being”pushed” to the device 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 needed 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 unit is working. The number that you find on the battery that came with your device are the max amount of amps which may be pulled by the device. The amount found on the charger is how many amps can be pulled simultaneously. In order to swap chargers, the amp number on the charger must equal or exceed the amp number recorded on the device’s battery. If a unit is paired with a charger which can’t support the amp necessity, it can burn out the power source 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 equal). *Website Note: if you have an older device, it might not work with USB ports that use the newest Battery Charging Specification.
If The Micro USB Charger’s Voltage Is Not 5v…
Some devices may have their voltage listed with a plus/minus on it like this: 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 device can take 5v minus 5 percent of 5v = 4.75 volts OR 5v and 5 percent of 5v = 5.25 volts. This means anything between 4.75 t0 5.25v is safe to use (so long as the amperage of the charger is equivalent to or greater than the device’s listed amperage).
An interesting point to note is all chargers provide a higher voltage than the batteries 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 direction to charge the battery. When you look at your car, it’s a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.
The problem with knockoffs, particularly cheap knockoffs, is they frequently don’t support the power requirements of the device, or are not built to maintain a steady flow safely. Overall, it’s better to stay with the charger made for the device you’re using.
Now You Understand How to Safely & Effectively Swap Chargers
I hope this article was able to help you. Now you know how to safely and effectively use a charger that did not include your smart phone, notebook, camera, tabletcomputer, or other device. Make certain you follow exactly what we said and you should be good to go!
