Can You Use Any Charger With Any Mobile 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 over the years. So the question becomes: is it safe to use a charger with your phone, notebook, camera, or tablet that is not the original manufacturer’s charger which came with the device?
Kinds of Chargers
In this article, we’ll focus on three types of chargers: notebook chargers, micro USB chargers (these are used with telephones, 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 common.
Laptop chargers are rather specific to the device they include. However, there can 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 for 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 different 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 charge with 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 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.
Somewhere on the power brick of the charger you’ll find a label with the charger’s voltage (V) and amperage (A). 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 manufacturer’s website.
Voltage is how much power the charger will draw into the apparatus, or how much is being”pushed” into the apparatus by the charger. A phone will usually pull up to approximately 5V, though a laptop can pull up to 25V. A charger must equal the voltage required by the device.
Amperage is how fast power is”pulled” to the device, or how much power is used by the device. The quantity 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 find on the battery that came with your device will be the maximum amount of amps which can be pulled from the device. The amount found on the charger is how many amps can be pulled simultaneously. If a unit is paired with a charger that cannot support the amp requirement, it may burn out the power supply 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 faster charging (so long as the voltage is equivalent ). *Site 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 Is Not 5v…
Some devices may have their voltage recorded using a plus/minus on it like that: 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 point to note is chargers provide a higher voltage than the batteries they charge. That is pretty much how they work. There needs to be a voltage differential to generate 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.
Stay Away From Cheap Knockoff Chargers
The problem with knockoffs, particularly cheap knockoffs, is they frequently don’t support the energy needs of the apparatus, or aren’t built to maintain a steady flow securely. This can cause damage to the device but can also pose a safety/fire hazard. Overall, it’s best to stay with the charger designed for the device you are using.
Now You Understand 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, notebook, camera, tablet, or other apparatus. Make sure to follow what we said and you should be good to go!
