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 is not the original manufacturer’s charger which came with the device?
Kinds of Chargers
In this guide, we’ll focus on three types of chargers: laptop chargers, micro USB chargers (these are used with telephones, tablets, and cameras), and Apple Lightning Connectors. While some devices have chargers using a slightly different head or charging cable, these are the most frequent.
Laptop chargers are fairly 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 might not be the best charging amperage or voltage to 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 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 (based on its listed 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 port, a connector can be used to control the Lightning Connector.
The Plugs Must Be The Same
For a charger to be used 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 so far as charging heads, whilst notebook chargers are usually specific to both make and model. However, the plug fitting firmly is only 1 part of this equation.
Somewhere on the power brick of the charger you’ll find a tag 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 found at the base of the charger, in which it would meet up with the wall. For the device you’re trying to control, 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 into the device, or just 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. This is important: drawing too high of a voltage could short out the device and possibly even start a fire, while too low a voltage will fail to charge the battery.
Amperage is how fast power is”pulled” to the device, or how much electricity is used by the device. The amount of volts will never 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. The number 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 listed on the device’s battery. If a unit is paired with a charger that cannot support the amp necessity, 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 may not work with USB ports that use the newest Battery Charging Specification.
If The Micro USB Charger’s Voltage Isn’t 5v…
Some devices may have their voltage recorded with 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% of 5v = 5.25 volts.
An interesting thing to note is chargers supply a higher voltage than the batteries they charge. That is pretty much how they operate. There has to be a voltage differential to generate the necessary current flow in the correct 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.
The issue with knockoffs, particularly cheap knockoffs, is that they often don’t support the power requirements of the device, or aren’t 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’re 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 effectively use a charger that did not include your smart phone, notebook, camera, tabletcomputer, or other apparatus. Be certain to follow what we said and you should be ready to go!
