The same recorded data is plotted for discharge energy rather than capacity, factoring in the slightly higher-than-5V output, but the trend is virtually identical as the small changes in temperature did not seem to have an effect on the output voltage. The underneath carries the barcode number of 848116029696 and shows a number of their worldwide subsidiaries. The Australian Regulatory Compliance Mark is shown along with the CE certification. Factors such as the device’s charging speed, the cable used, and the power bank’s conversion efficiency can also impact how long a 5000mAh power bank lasts. For example, using a fast charging cable or charging multiple devices simultaneously may shorten the overall usage time. Everybody on our gift list who got a new iPhone is going to get an Anker Nano Power Bank (22.5W) this year. This cute little charger is perfectly sized to sit beneath your favorite smartphone, plugged into the USB-C port with a little plug that opens out or hides away for a sleek look. The highlighting feature of this power bank is its innovative bypass technology that allows you to charge your phone and the power bank simultaneously.

It is equipped with a massive 5000 mAH battery that can charge your phone multiple times. In terms of connectivity, you get a single USB-A output port and an option to choose between a USB-C or a Micro USB input port for charging. 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.

Conclusion

In recent years, power banks have improved exponentially. As we all grow increasingly reliant on our electronic devices, power banks have become smaller, lighter, and more capable than ever before. The PowerEasy power bank has a 5000mAh battery capacity which is enough to charge an iPhone up to 2.5 times, depending on the model you use. That being said, you will need a micro USB cable to charge this device which might be a hassle for some Apple users.

To ensure the longevity and optimal performance of your power bank, here are some helpful tips to extend its lifespan: 1. Choose a High-Quality Power Bank Generally, power bank capacity is measured in milliamps per hour — mAh. This unit indicates how many milliamps of electric current a given power bank can deliver per hour. 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.

Introduction

It’s important to note that the mAh rating alone does not determine the overall performance of a power bank. Other factors, such as the efficiency of the conversion from stored energy to usable power, the number of charging ports, and the quality of the internal components, also play a significant role. 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. We like that this simple power bank is free of frivolous features. It serves its purpose perfectly and doesn’t pretend to be anything more than a reliable power bank. The easy-to-read LED display allowed us to keep accurate tabs on its battery life. Its rate of power delivery is right up there with the best banks on the market, but the bank itself is fairly low to charge. 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 Smartphones typically have battery capacities ranging from 2000mAh to 4000mAh or more. The power consumption of smartphones varies based on factors such as screen size, processor efficiency, and usage patterns. On average, a smartphone may consume around 1000-2000mAh per full charge. This means that a 5000mAh power bank should be able to provide 2-3 full charges for most smartphones. 2. Tablets
