How Long Does a 10000 mah Battery Last?

A 10,000mAh battery lasts longer than the average 3,000mAh phone battery. The duration of how long your 10,000mAh battery lasts depends on how much current is being drawn from it. If your device draws 1mA, the 10,000mAh battery can last 10 hours before running out of power. But if your device uses 10,000mA, the battery may only last for one hour.

How many hours does a 10000mAh power bank last?

The 10000mAh battery life depends on the device and the number of hours used. Your battery with a 10,000mAh capacity has a lifespan directly proportional to the amount of electricity pulled from it. When your device draws 1mA, the 10,000mAh battery could last up to 10 hours. However, if your device is using 100mA, then you won’t get more than an hour out of the battery pack before you need to recharge again.

Tip: Use power banks only when necessary and avoid overcharging them by plugging them in whenever they are fully charged (4-8 hours). When they have reached their maximum capacity, lithium-ion batteries do not require any additional charging and can even be damaged by further charging.

How long does a 10000mah power bank last?

Many people wonder how much power they need in a battery to last throughout the day. If you plan to use your device casually, 10000mAh is enough for most users to get through the day. If you use your device heavily throughout the day, you should invest in one with at least a 20,000mAh capacity.

How many charges can 10000 mAh do?

It’s possible to calculate the number of charges it would take to drain a phone, but we recommend you ensure your device has a 10000mAh battery to avoid ‘battery anxiety.’

1 milliamps = 0.001 amps or 100mA (Amps)

It means a 1000 mAh battery can provide 1/1000th of an amp before it’s fully drained, so if we use the formula below:

mAh x Amp Hours / 1000 = mA (milliAmps) 10000 x .01 / 1000 = 0.10 or 10mA (This gives us the total number of charges). Divide this by the Amps used per charge, and you get the approximate number of hours the phone would last in charge mode. However, most devices do not draw a constant current throughout a charge cycle. For example, if your device typically consumes 10mA when in use but only draws 1mA while idle, it could last approximately 500 hours.

When you consider how long it would take to charge this phone, it is simple to understand why having a backup power source, such as an external battery pack, would be beneficial. If you find that your devices do not have batteries with a capacity of 10000mAh, but you still want to use them, obtain a portable power source such as an External Battery Pack. This way, you can keep all of the features on your smartphones or other electronics without worrying about the battery dying at inconvenient times.

How much is 10000 mAh

A 10000mah battery is the equivalent of about 3.7 watt-hours or 3.7 amp-hours. It can estimate the run time of devices that require a certain number of watt-hours or amp-hours. For example, if a device requires a 2500mAh battery, on a 10000 mah meaning, it will run for about 4 hours.

Also, a 10000mah battery has enough power to charge an iPhone 12 up to 4 times or an iPhone 13 up to 3 times. It can also fully charge most laptops once.

Which is better, 20000mAh or 10000mAh?

The 20000mAh battery has a bigger capacity, making it longer to charge than the 10000mAh. If you’re someone who doesn’t mind watching what you do on your phone or having to worry about your phone suddenly dying because of a low battery, then I would recommend getting the 20000mAh one. With that said, expect it to be more expensive than the other one.


A power bank or external battery pack is a necessity to keep you updated and connected with your devices. When choosing whether to buy a battery with 10,000mAh or 20,0000mAh, consider the time you spend using the device, type of device (e.g., iPhone or laptop), and cost. Additionally, if you want to know the battery’s life, you can use a Battery Life app, giving you ample time to find a charger before the battery dies.
