A 10,000mah power bank is going to last 10 hours on a device that uses 1,000ma an hour. If the device uses 500ma, the power bank is good for about two hours. Power Bank Capacity Explained . The math is straightforward. So, when you see a battery advertised as being 5200mAh, that’s a measure of its capacity. But it’s not a measure of how long the battery will last in real-world use. Also, The 5200mAh on the phone means that the battery can last for 5.2 hours with a load of 1 amp, or 1 hour with a load of 5.2 amps. We’re starting this guide with a few heavy power banks, especially this Excitrus NitroCharge Pro power bank. This charger has a 25,600mAh power bank. Considering that the S22 has a 3,700mAh battery, the S22 Plus has a 4,500mAh battery, and the Galaxy S22 Ultra has a 5,000mAh battery, a 25,600mAh capacity can charge these phones to full power Likewise, the following is a table with the most popular and latest Samsung models. Smartphone Model. Pone battery capacity. Power bank capacity for 1 charge. Power bank capacity for 2 charges. Samsung Galaxy Note 10+/Note 10+ 5G. 4300 mAh. 6450 mAh. 12900 mAh. Here’s a breakdown of how long a 20000mAh power bank will last, based on its capacity: 10000mAh: 10 hours; – 15000mAh: 15 hours; 20000mAh: 20 hours; As you can see, the higher the capacity of the power bank, the longer it will last. So if you need a power bank that will last all day long, go for one with a high capacity like 20000mAh. The 2500 mAh battery might last just 2-3 hours of intensive usage before going flat. So you can expect a 2500 mAh smartphone battery to last anywhere from 2-12 hours depending on your usage. For comparison, the iPhone 14 Plus has around a 4300 mAh battery for up to 26 hours video playback. To illustrate, let's say you're using a 30,000mAh 3.7V portable battery to power a 10W camping lantern. To estimate how long you'll be able to run your lantern, you first need to calculate the battery's watt hours. 30,000mAh × 3.7V ÷ 1,000 = 111Wh. Now that you know its watt hours, you can estimate its runtime by doing the following calculation: This calculator is designed to show exactly how many times a power bank with a specific capacity (1000 mAh, 2000 mAh, 5000 mAh, etc) can charge your specific phone model. Enter the model of your phone and the capacity of a power bank in the forms shown in the figures. Step 1: Input your phone model in the first field. The calculator will find B6g94.
