Best Portable Charger for Android to Buy 2024

Best Portable Charger for Android to Buy 2024

Navigating the maze of tech gadgets to find the best portable charger for Android devices requires a keen eye on certain specifications to guarantee compatibility, longevity, and efficiency.

This article will unveil the essential factors to look for when selecting an ideal power companion for your Android smartphone or tablet, followed by a curated list of top-tier portable chargers that stand out in performance, durability, and user convenience, making sure that your device stays powered up even during the busiest days. 

Things to Know When Picking the Right Charger for Android Devices 

Here are some tips to help you choose the best charger for your needs:

Find out How Much Power You Need in Watts (W)

The foremost consideration when choosing a charger is the power requirement of your device, expressed in watts (W). This figure can be found on your device's specifications sheet or within the manual and is pivotal in determining how quickly your device can charge. The wattage varies widely across devices, typically ranging from 18W to 80W for most smartphones, with some, like certain OnePlus models, supporting even higher speeds exceeding 120W. This power rating signifies the maximum amount of power the device can handle for optimal charging. It's essential to opt for a charger that can deliver at least this power level to ensure you can utilize your device's full charging capability.

Check the Charging Protocol Supported by Your Device 

The charging protocol is the language your device speaks with its charger, dictating how power is delivered. While some Android devices support universal standards like USB Power Delivery (PD), others may use proprietary technologies like OPPO's SuperVOOC or OnePlus' Warp Charge. It's crucial to ensure compatibility; if your device supports a proprietary standard, using a third-party charger may not unlock your device's fastest charging capabilities. In contrast, chargers that adhere to universal standards like USB PD can typically be interchanged between devices without issue.

Pick a Charger Matching Your Device’s Power Requirement

Once you have determined both the required wattage and the supported charging protocol of your device, it's time to find a charger that aligns precisely with these needs. Selecting a matching charger ensures that you're neither underpowering your device, which can lead to sluggish charging times nor risking damage by using an adapter that delivers too much power. If your device's spec sheet indicates a specific charger wattage for optimal charging, targeting a charger that meets or exceeds that rating is advisable, to account for power loss over cables and efficiency.

Make Sure Each Port Supports Your Required Standards

If you are opting for a charger with multiple ports, it's necessary to confirm that each port meets the charging standards your device requires. Often, multi-port chargers have varying capabilities for each port, and the total output when multiple devices are connected can be divided unequally. For instance, not every port on a charger may support Quick Charge or USB PD, which might result in one device charging swiftly while another charges at a more standard pace. Additionally, keep in mind the total wattage that the charger can provide—if it is, say, a 60W charger with three ports, it might not be able to simultaneously provide fast charging for three devices if that requires more than the 60W maximum it can deliver.

Here are some commonly asked questions about the best portable charger for Android.

Should I Get 10000MAH or 20000MAH Power Bank?

The choice between a 10000MAH and 20000MAH power bank mainly depends on your specific needs. If you often need to charge multiple devices or have devices with large battery capacities, a 20000MAH power bank is more suitable. But, if you're looking for something lighter and more portable, a 10000MAH power bank should serve you sufficiently.

How Many Hours Does a 20000MAH Power Bank Last? 

The duration of a 20000MAH power bank depends on the power consumption of the device being charged. For instance, if your smartphone has a big 4000mAh battery capacity and is completely drained, a 20000MAH power bank can theoretically charge it five times. However, considering energy loss during transfer and efficiency rates, you might get around 4 full charges.

Do Power Banks Lose Charge When Not in Use?

Yes, portable power banks lose charge when not in use due to the internal circuit's minimal power draw. However, the loss is very small. Typically, a fully charged power bank should retain its charge for several weeks, although this can vary depending on factors like the power bank's quality, age, and ambient temperature.
