About this deal

Note: These are simplified examples. Batteries lose capacity as they age (and may not even output their rated capacity to begin with). Also, depending on what type of battery you have, it may not have 100% usable capacity. How to Convert Amps to Milliamp Hours (A to mAh)

New power banks are now available in the market, supporting fast-charging and often delivering up to 9 Volts. Most of the power banks have battery cells internally connected in series to achieve the required voltage. For example, if a power bank has four Li-ion cells connected in series, it will have an overall voltage of 14.8 Volts. Finding the right charger capacity: You'll often see a four to five-digit number, with the letters mAh following it, and that's your first big indicator of how much this charger is right for you. If you're constantly refueling your phone and other gadgets, go for at least 10,000mAh. For each extra device you charge, add at least 5,000 to the mAh rating you're looking for. Just need to prevent your device from hitting 0 on late nights out? You'll be good with something in the under 5,000 mAh rating, provided you remember to charge it often.AA batteries usually have the shortest mAH life, while D cells have much greater mAH. A AA battery may have a mAH of 2000, while a D cell may have 10,000mAH. For this supply per hour of use. Again, as an example, a 1900mAH battery can supply 1900mA of current to a circuit As you already know, 10,000 mAh portable chargers can last a long time because of their battery capacity. However, you can prolong their lifespan through the way you use them too. mAh is frequently used to measure the battery capacity of smartphones, external batteries and tablets Be mindful of the temperature – Again, charging your power bank at a temperature that is over 40° is not the best. You should also avoid charging it at a temperature of less than 4°. The ideal temperature for these lithium-ion batteries is anywhere between 5 and 25 degrees.

But again, you also have to factors like the newness of your smartphone and power bank. The longer you have had them, the lower their capacity becomes. You also have to consider how well you have charged your power bank. How Many Times Will a 10,000 mAh Charge a New Smartphone? A medium-capacity power bank is the perfect choice if you're traveling to locations where you frequently use your phone, and it might take some time before you find a wall charger. A power bank with a capacity of about 7,000 mAh can be used to charge multiple small gadgets, including headphones, as well as your phone. You can share your portable charger with two other people, but only one other person at most, because most of these devices come with only a pair of charging outlets.After reading the above content, you should already know what is mAh. You shouldn't worry about choosing a power bank because there are many options available that will meet your demands. For daily use with a phone or while on the go, consider power banks with a capacity of between 3,000-5,000 mAh. Your light uses around 0.125 amps on average. That's helpful to know if you want to resize your battery or use it to power more devices later on. So batteries with higher mAH's are more desirable, because they can last for a longer period of time, since they have a higher current capacity. Anker Astro E3 10000mAh External Battery: The Anker Astro3E is one of the best external batteries and holds 10,000mAh. I wrote a review of the Anker Astro E3 here.
