What is the real output capacity of a Power bank?

图片
Do you know how many times you can recharge your cell phone with a 10000mAh or a 20000mAh power bank? A very common mistake among those of us who want to know the number of charges we can get on our devices with a  power bank  is to divide the capacities of both devices, i.e.: Number of Charges = Power Bank Capacity (mAh) / Smartphone Capacity (mAh) For example, if you have a smartphone with a 2500mAh battery capacity and you want to buy a 10000mAh power bank, how many charges could you get? If we apply the above formula we get 4 full charges: Number of Charges = 10000 mAh / 2500 mAh = 4 charges THAT'S A BIG MISTAKE!! We are sorry to tell you that this calculation would be incorrect because the 10000mAh of the power bank refers to the capacity of its internal battery. A result closer to reality would be to use the actual capacity available at the output USB port of the power bank: Number of Charges = Actual Power Bank Capacity / Smartphone Capacity If ...

How do you choose a power bank with the right capacity?

图片
The capacity of your power bank determines how often you're able to charge your smartphone, tablet, or laptop. As with smartphone batteries, the capacity is expressed in in milliamps per hour. But you can't simply compare the capacity of a power bank with that of other devices. Due to energy loss during charging, about 1/3 of the capacity of a power bank is lost. Here, you can read how this works. 1/3 of the capacity is lost The technical side of it is complicated, but the rule is simple: the actual capacity of a power bank is about 2/3 of the capacity indicated. The rest disappears during power conversion or is lost during charging, especially as heat. This means power banks with a battery of 10,000mAh or 20,000mAh actually have a capacity of only 6,660mAh or 13,330mAh. This rule applies to high-quality power banks alone. Budget power banks from cheap wholesalers are even less efficient, so they lose even more energy.   Smartphones: a power bank with 10,000mAh With a 10,000mAh...

Which is better for power bank, 18650 or polymer batteries?

图片
Early mobile power gives most users the impression that it is big and heavy, while today's mobile power is very small, especially the shared ones. Those who have used them will feel very light. This is a credit to the polymer lithium-ion battery. In fact, many electronics can perform better thanks to polymer lithium-ion batteries, such as TWS Bluetooth headphones and special small electronic devices. Unlike a few years ago, fewer and fewer 18650 lithium-ion batteries are used in   power banks . Are they really being phased out? Besides size and weight, what is the difference between polymer Li-ion batteries and 18650? That's what we'll discuss today.     What is an 18650? There are two important types of batteries on the market today, one is the lithium-ion battery and the other is the polymer battery.

The difference between plugging in and unplugging the laptop power adapter

图片
    The difference between plugging in and unplugging the laptop power adapter There is almost no difference between plugging in and unplugging the power adapter when the laptop is turned off. If the power adapter is plugged in all the time, there will be a power drop and it will consume more power than if it is not plugged in. Many laptops have indicator lights on the power switch button. When always plugged in, the light will stay on, indicating that the laptop is plugged in. If it is not plugged in, the light will go off. There is no other difference.   However, if the laptop is in working condition and the power adapter is unplugged, the situation is very different. Most laptops automatically go into power saving mode, which affects the brightness of the display and the performance of the computer.   Why would anyone recommend "unplugging"? The advice is good, but it is necessary to find out why it is recommended. The laptop's power adapter converts residential e...

Improving your phone's battery availability

图片
We analyzed the power consumption of different smartphone components in a series of typical scenarios. We concluded that there are some simple software and hardware strategies that can be used to extend battery life. ✱ Reduce screen brightness. The easiest way to extend battery life while maintaining full functionality is to reduce screen brightness. For devices with organic light-emitting diode (OLED) displays, you can also use the "bright when dark" option to see. ✱ Turn off cellular networks or limit talk time. The connection to the cellular network uses the Global System for Mobile Communications (GSM) module. GSM is the primary energy-consuming component of the phone, so it is beneficial to turn it off completely or at least limit talk time. ✱ Use Wi-Fi instead of 4G. Wi-Fi uses up to 40% less power for Internet browsing compared to 4G, so turning off cellular data and switching to Wi-Fi will help extend battery life. ✱ Limit video content. Video processing is one of the...

To make your phone's battery last all day

图片
As cell phone users, all we want is enough battery life. Frustratingly, the older a device is, the less power it seems to have. In fact, the battery life of our phones on any given day depends on two key factors: how we use them on that particular day, and how we've used them in the past. Cell phones use lithium-ion batteries for energy storage. In this type of battery, lithium metal and lithium ions move in and out of the individual electrodes, causing them to physically expand and contract. Unfortunately, these processes are not fully reversible, and as the number of charge and discharge cycles increases, the battery loses its charge capacity and voltage.     To make matters worse, the electrolyte (conductive liquid) that connects the electrodes also degrades during these cycles. The ability of a lithium-ion battery to store charge depends on its degree of degradation. This means there is a link between the way we handle our devices today and the charge capacity available in...

The following is our charger engineers explain the four common charging myths!

First: charging the phone too many times There is a saying: each cell phone battery has a fixed number of charges, if the number of charges is too much, it will accelerate the battery aging strains! This practice is actually only the practice of nickel batteries, lithium batteries are different, often charging is actually a bit good for the battery! When the phone is low on power, the battery should start charging in time. Second: the wrong use of chargers If you use the iphone plug to ipad charging, you will find that it is not generally slow! If you use a high power plug to charge your phone with a low power plug, it will be much faster! So the best choice when charging the original charger! Third: mixed use of charging cable Charging line is also the same, it is best to  choose the original charging line , but also in a few long like charging line well marked, in order to avoid mixing, out, we will choose the charging line, like to randomly tie the line is shorter, if the chargi...

Will overnight charging hurt your phone's battery?

You will get a bad battery for charging a cell phone all night long, and many people believe this is the case, but is it true? Or are these just internet rumors? Check out the experts' answers. Recently, a Canadian battery expert refuted the idea of  charging a cell phone battery  all night long, saying that electronic products, including smartphones, using lithium batteries will automatically cut off when fully charged and will not damage the battery. On the contrary, the battery life will be shortened only when charging with household dry batteries. And charger experts Hollington said, iphone generally will not be overcharged, even if the iphone charged to 90% of the power, will not damage the battery. He explained that the lithium battery "charge cycle" is limited, but a partial charge will only be proportional to the "charge cycle". If you charge at 90%, you will only use 10% of the charging cycle.  

How does wireless charging work?

Inductive wireless charging is a way to charge your phone without any annoying cables. Most Android phones of the last few years can use Qi wireless charging pads. Qi is a wireless charging standard shared by most companies for compatibility. All you have to do is plug in the charging pad and place your phone on it. The process uses electromagnetic induction to charge the battery of your Android phone. This involves a series of very flat coils inside the charging pad. The pad creates an electromagnetic field that powers your phone in order to charge the battery.     Initial Troubleshooting There are two most common issues that can prevent an Android phone from  charging wirelessly on a tablet . The second is that there may be no power flowing to the pads. Check to make sure the charging pad is plugged into a power source. The second is that your Android does not support wireless charging, which older models do. Check this list and make sure your Android can charge wireles...

  What capacity do I need? Capacity, expressed in milliamp hours (mAh), is a rough indication of charging capacity. The higher the number, the more power it can provide to your device before the mobile power source runs out of juice. Try to find a mobile power that can fully charge your smartphone at least twice before you need to recharge it, as this will give you a day or two of coverage at a time. Mobile power can range from a single charge (3,000mAh) to well over (20,000mAh), with most of the latest smartphones having a battery capacity of about 3,000mAh. a 10,000mAh mobile power should be able to charge your smartphone 3 times, while a 20,000mAh mobile power should be able to charge your smartphone more than 6 times.   How long does it take for a mobile power to charge my device? Most models can charge a standard 3,000mAh device like a smartphone in about 90 minutes; no longer a red flag. The charging time of a mobile power is not a big deal as you can plug it in overnigh...
