Every cell phone, laptop computer, and tablet appear to come with their own battery charger. If you resemble me, you have actually probably put together quite a few battery chargers for many years.
So the question becomes: is it safe to utilize a charger with your phone, laptop, video camera, or tablet that isn’t the original maker’s battery charger that included the gadget?
In this short article, we will concentrate on three kinds of battery chargers: laptop computer chargers, micro USB battery chargers (these are utilized with phones, tablets, and electronic cameras), and Apple Lightning Connectors. While some gadgets have battery chargers with a somewhat various head or charging cable, these are the most typical.
Types of Chargers
Laptop battery chargers are relatively particular to the gadget they include. There may be some generic chargers that boast the ability to be interchanged between laptops. This always requires altering of the charger “head” and may not be the optimum charging amperage or voltage for your gadget.
Micro USBs are theoretically designed to be interchangeable, and are basic in a lot of smartphones, Android gadgets, and tablets. Micro USB battery chargers generally have the exact same voltage, however might draw various amps. I’ll discuss this more later and how to understand if the charger is safe to utilize (depending on its noted amps and voltage).
Apple Lightning Connectors are basic on all brand-new Apple devices, consisting of iPads and iPods. For older gadgets with a 30-pin charge port, a connector can be used to charge with the Lightning Port.
The Plugs Needs to Be The Same
In order for a charger to be used on a various gadget, it is essential that the plug of the charger (the “head”) healthy firmly into the charging port of the gadget. Micro USBs are the same across the board as far as charging heads, while laptop computer battery chargers are frequently particular to both make and design. The plug fitting securely is only one part of the equation.
How Voltage and Amperage Matter
Somewhere on the power brick of the battery charger you will discover a label with the charger’s voltage (V) and amperage (A). For laptop computer battery chargers, this charging brick is often midway down the charger and usually looks precisely like it sounds– a brick. For other kinds of chargers, like a mobile phone charger, this information is usually found at the base of the charger, where it would meet the wall. For the device you are trying to charge, the voltage and amperage required will be found on the battery that featured the gadget or on the maker’s website.
Voltage is just how much power the charger will draw into the gadget, or how much is being “pressed” into the gadget by the battery charger. A phone will usually pull up to around 5V, while a laptop can pull up to 25V. A charger needs to equal the voltage needed by the gadget. This is necessary: drawing too high a voltage could short out the gadget and potentially even start a fire, while too low a voltage will stop working to charge the battery.
Amperage is how rapidly power is “pulled” into the gadget, or just how much power is utilized by the gadget. The amount of volts will never ever alter, however the amount of amps that the device pulls might alter depending on how difficult the device is working. The number that you find on the battery that featured your device will be the max amount of amps that can be pulled by the device. The number found on the charger is the number of amps can be pulled at once. In order to exchange battery chargers, the amp number on the charger should equal or go beyond the amp number noted on the device’s battery. If a gadget is coupled with a battery charger that can not support the amp requirement, it can burn out the power supply and kill the device.
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 might not deal with USB ports that utilize the brand-new Battery Charging Spec.
If The Micro USB Charger’s Voltage Is Not 5v …
Some devices might have their voltage noted with a plus/minus on it like this: 5v +- 5%. If this is the case, you can utilize a battery charger ranked at 4.75 to 5.25 v because that score is informing you is that the device can take 5v minus 5% of 5v = 4.75 volts OR 5v plus 5% of 5v = 5.25 volts. So this indicates anything between 4.75 t0 5.25 v is safe to utilize (as long as the amperage of the charger is equal to or higher than the device’s noted amperage).
An intriguing thing to note is all chargers provide a greater voltage than the batteries they charge. That is basically how they work. There has to be a voltage differential to produce the needed existing flow in the appropriate instructions to charge the battery. If you take a look at your automobile, it has a 12V battery, however typical generators supply 13.8 to 14.4 V charging voltage to the battery.
Keep Away From Inexpensive Knockoff Chargers
The problem with knockoffs, particularly inexpensive knockoffs, is that they typically do not support the power requirements of the device, or are not constructed to preserve a constant circulation securely. This can trigger damage to the device but can also position a safety/fire danger. In general, 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 effectively use a charger that did not come with your smart phone, laptop, camera, tablet, or other device. Make sure you follow what we said and you should be good to go!
What happens if you battery ages and isn’t performing well anymore? Well, you have to use other methods and actually recondition it! And that’s why we recommend the EZ Battery Reconditioning program.
