Tablets generally have larger batteries compared to smartphones, with capacities ranging from 5000mAh to 8000mAh or more. Due to their larger size and higher processing power, tablets typically consume more power than smartphones. On average, a tablet may consume around 3000-4000mAh per full charge. Therefore, a 5000mAh power bank may provide 1-2 full charges for most tablets. 3. Laptops It is perfect for charging a range of devices such as torches, mobile phones, tablets etc via the standard USB-A port on the top with a QC 3.0 output of up to 2.4 A (18 W max), and is compatible with the Nitecore HU60 USB head torch. You don't have a magnetic phone: You don't need an iPhone to enjoy the magnetic charging, but you'll need a case that lines up your phone with Apple's MagSafe wireless configuration, or else your phone won't charge properly.

The power consumption of various devices can vary significantly, and understanding these differences can help determine how long a 5000mAh power bank will last when charging different devices. Here is an overview of the power consumption of common devices: 1. Smartphones Usually, slim power banks have less battery capacity as compared to traditional ones. If you have a high-capacity smartphone, you might only get 2-3 full recharges out of your power bank. Our favorite power bank has a 10,000mAh battery, and the Samsung Galaxy S23 Ultra has a 5,000mAh battery, so the math should be simple, right? It charges twice. Except that's not how it works. Power banks are not 100% efficient, and even though you start with plenty of power, a lot of it is lost in the charging process. When you add in the awesome build and the use of Panasonic battery cells to make the Output capacity very close to its initial capacity, then this small power bank is one the best in this mini area of portable chargers.The PowerCore III fully charged an iPhone 13 just over six times. Anker claims it can charge three devices simultaneously. During testing, it easily charged two smartphones at the same time.

The charging speed of each of the ports is 3A when you use it as a power bank and the max output is also 3A. While you’re using it as a USB wall charger, the ports have a charging speed of 5V/2.1A, and that’s to prevent any overheating. The discharge data plotted against time showed that as long as you respected the power bank’s advertised maximum current, the output voltage was very consistent throughout the discharge, with the output voltage being fairly accurately set. The output voltage does elevate slightly when there is light loading, but the voltage is well within specifications. When overloaded, however, the voltage is below expectations and the unit may continue to operate depending on the level of overloading. At the full rated 2.1A load, it was able to run for 1h 22m 54s. Using the manufacturer-recommended charging cable and adapters can help optimize the charging process and prevent any potential damage due to incompatible or low-quality charging accessories. Quality cables and adapters ensure a stable and efficient power transfer, reducing the strain on the power bank’s battery cells. 6. Avoid High-Speed or Rapid Charging This PowerCore Fusion 5000, slows down its charging speed because while it’s plugged into an AC outlet, that’s also how it can recharge. That said, this power bank also makes use of a Micro-USB input if you want to recharge it that way too, at a recharge speed of 5V/2.0A. In terms of charging, this massive power bank can charge an iPhone 15 more than five times. It can charge a big Galaxy S23 Ultra's 5,000mAh battery three-and-a-half times. Best of all, it charges at the fastest speed available on most of your favorite phones (excluding Oppo/OnePlus's unusual SUPERVOOC battery).Furthermore, the cycle of charging and discharging the power bank itself will affect its overall lifespan. Over time, the capacity of the power bank’s battery cells may degrade, resulting in reduced charging capacity and shorter usage time. Over 20,000 mAh power banks are typically for camping or vacation because they can charge all of your portable electronics for a day. That’s because there aren’t many Mini power banks on the market that make use of USB-C. Also, the only port on this Aukey power bank is the USB-C port and you can use it as an Output and input. The output charging speed is 5V/3.0A, while the input recharge speed for this power bank is 5V/2.0A. Moreover, being PowerIQ 3.0-enabled, our 5000mAh power banks provide the swiftest possible charging speed, allowing you to charge an iPhone 13 Pro in a short span of 1.3 hours. But our 5000mAh power banks have way more advantages. For example, the long-lasting battery of our 5000mAh power banks can retain up to 90% of their original capacity even after 500 days of consecutive daily use. The processed data of capacity shows the capacity to be remarkably stable over all cycles with no clear degradation trend emerging. Instead, the modified car fridge I was using to maintain temperature had difficulty given the Australian summer plus the unit’s own power dissipation, thus the average temperature did stray from the nominal 25 degrees Celsius somewhat. The recorded deviations in capacity are very strongly correlated with the deviation in temperature. The baseline discharge capacity at 2A appears to be about 2,978mAh @ 5V which would be equivalent to 4,024mAh at 3.7V. If the power conversion is about 80% efficient, then the cell capacity would be spot-on the rated 5,000mAh.

Increasing the load to 2A, however, reveals a ripple of 151mV peak-to-peak which is now starting to get a bit high. It isn’t much more than what some OEM chargers put out, but is not all that “quiet” compared to many other units. At the rated limit of 2.1A, this increases to 161mV. It would have been nicer if these figures were a bit lower, but it is not likely to cause any major issues. 50-cycle Endurance Test We’ve been testing the Lion Trek for several months. Though it’s a bit too big and inconvenient for airline travel, it’s been our go-to power bank for car camping. On a single full charge, the Lion Trek recharged an iPhone 13 nine times. It kept a MacBook Air alive for three days of frequent use. According to its display, the Lion Trek only used 5% of its total battery life to fully charge a pair wireless earbuds. Power banks are physical stop gaps that prevent dreaded cases of DPS (dead phone syndrome). Whether you forgot to plug in overnight, or you’ve been traveling all day without access to an outlet, power banks are a lifeline for you and your portable electronics.

Conclusion

To extend the lifespan of your power bank, choosing a high-quality device, storing and using it correctly, charging it regularly, and avoiding overcharging or over-discharging are essential. Using recommended charging cables and adapters, avoiding high-speed charging, and disconnecting devices after charging also contribute to a longer lifespan.
