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 quite a few chargers through 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 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 phones, tablets, 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 fairly unique to the device they include. However, there may be some generic chargers which boast the ability to be interchanged between notebooks. This always requires changing of the charger”head” and may not be the optimal charging amperage or voltage to your device.
Micro USBs are designed to be interchangeable, and are standard in many smartphones, Android apparatus, and tablets. Micro USB chargers typically have the exact same voltage, but may draw different amps. I will explain this further later and how to know whether the charger is safe to use (depending on its recorded amps and voltage).
For older devices with a 30-pin charge port, a connector can be used to charge with the Lightning Connector.
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 so far as charging heads, whilst notebook chargers are often specific to both make and model. However, the plug fitting firmly is only 1 part of this equation.
How Voltage and Amperage Matter
Somewhere on the power brick of the charger you will 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 found at the base of the charger, in which 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 manufacturer’s website.
Voltage is how much power the charger will draw in the device, or how much is being”pushed” into 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 needed by the device. This is important: drawing too high a voltage could short out the device and potentially even start a fire, while too low a voltage will fail to charge the battery.
Amperage is how fast power is”pulled” into the device, or how much electricity 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 unit is working. The number that you locate on the battery that came with your device will be the max amount of amps which may be pulled by the device. 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 requirement, it can burn out the power supply and kill the device.
So if you have a modern USB device (smart phone, tablet, or camera) you can plug into a high-amperage USB port and enjoy faster charging (as long as the voltage is equal). *Site Note: if you have an older device, it may not work with USB ports that employ the new 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 that: 5v +- 5%. If this is true, 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% of 5v = 4.75 volts OR 5v and 5 percent of 5v = 5.25 volts.
An interesting point to note is all chargers supply a higher voltage than the batteries they charge. That is pretty much how they work. 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 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 issue with knockoffs, particularly cheap knockoffs, is that they frequently don’t support the energy requirements of the apparatus, or are not built to maintain a steady flow securely. This can result in damage to the device but can also pose a safety/fire hazard. Overall, it’s better to stick with the charger made 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. Be certain you follow exactly what we said and you should be ready to go!
