Buying Guide
When it comes to purchasing a 20000mAh power bank, there are several factors to consider to ensure you get the best value for your money and a product that suits your needs.
Capacity
The capacity of a power bank, measured in mAh (milliamp hours), indicates the amount of energy it can store. A higher mAh rating means the device can store more energy and, therefore, charge devices more times before they themselves need recharging.
The RAV and the Anker 20000mAh both offer a high capacity of 20000mAh, ensuring multiple charges for your devices.
Charging Speed
This refers to how quickly the power bank can charge your devices. Some support fast charging technologies like Quick Charge (QC) or Power Delivery (PD), which can significantly reduce the time it takes to charge a device. The wattage (e.g., 18W, 30W) often indicates the speed.
The RAV 20000mAh boasts 18W PD and QC output, indicating that it supports fast charging technologies to speed up the charging process for your devices.
Number of Ports
The number of output ports determines how many devices you can charge simultaneously. Some models might also have varied port types, like USB-A, USB-C, or even AC outlets.
The Imuto 20000mAh can charge two devices simultaneously, showcasing its dual-output capability.
Display and Indicators
Modern power banks often come with LED displays or indicators that show the remaining battery percentage or charging status. This feature helps users gauge when the power bank needs recharging.
For example, the RAV 20000mAh is equipped with a display screen that intelligently shows the actual status of charging, allowing users to monitor the battery level.
Compatibility
It’s essential to ensure the power bank is compatible with a wide range of devices, from smartphones to tablets and even laptops. Some might support specific brands or device types more efficiently.
The Soaraise 25000mAh is highlighted as being compatible with all 5V devices, ensuring it can charge a wide range of gadgets from iPhones to Samsung devices.
Design and Portability:
The design pertains to the physical attributes of the model. A compact and lightweight design is preferable for those on the move. Some might also have rugged or waterproof designs for outdoor use.
The Xiaomi 20000mAh is specifically designed for outdoor activities, emphasizing its compact and travel-friendly design.
Price and Value for Money:
While it’s tempting to go for cheaper options, it’s crucial to ensure you’re getting good value for your money. A slightly pricier model might offer better durability, more features, or a longer warranty, making it a better long-term investment.
The Imuto 20000mAh is mentioned as offering good value for its price, suggesting that it provides a balance of quality and cost.
Safety and Protection:
Safety features are paramount. Good power banks have built-in protections against overcharging, overheating, short-circuits, and more. This ensures both the power bank and the devices being charged remain safe.
The Imuto 20000mAh comes with smart protection features, ensuring that your devices are charged safely without risks of overcharging or short-circuits.
Warranty and Brand Reputation:
Established brands often offer better customer support and warranties. A longer warranty period can be an indicator of the manufacturer’s confidence in the product’s quality. Brands like Anker ensure warranty coverage.
In order words, look for a device with the following characteristics:
- Charge multiple devices.
- To Purchase easily.
- Carry them anywhere.
- Charge devices in minimum time.
- Durable charging device.
- User friendly.

FAQs
What does mAh stand for?
mAh stands for “milliampere-hour,” which is a unit of measurement used to describe the amount of electrical charge a battery can hold. It is commonly used to measure the capacity of rechargeable batteries in electronic devices such as smartphones, laptops, and tablets. The higher the mAh rating, the longer the battery can typically last before needing to be recharged.
How many charges do you get with a 20000 mAh power bank?
The number of charges you can get from a 20000 mAh power bank depends on the capacity of the device you are charging and the efficiency of the power bank. However, here is a rough estimate based on the assumption that the power bank is 100% efficient and the device being charged has a battery capacity of 3000 mAh:
20000 mAh / 3000 mAh = 6.67
This means that you could get approximately 6-7 full charges for a device with a 3000 mAh battery capacity from a 20000 mAh power bank. However, keep in mind that actual charging capacity may vary depending on various factors such as the age and condition of the battery in the device being charged, the usage of the device during charging, and the quality and efficiency of the power bank.
Can a power bank damage your phone?
This is generally safe and will not cause damage to your phone, as long as you use a high-quality model designed to work with your phone’s specific charging needs.
However, using a low-quality or counterfeit model can potentially cause damage to your phone, as these products may not be designed to meet safety standards and may not regulate the charging process properly. Additionally, using a model that is not powerful enough for your phone’s charging needs can cause slow charging or incomplete charging, impacting the overall health of your phone’s battery.
How do you know if the power bank is fully charged?
- Check the LED indicator: Many models have LED lights that indicate the charging status. When the device is fully charged, the LED indicator will typically turn off or show a solid light.
- Check the charging time: The charging time can vary depending on the capacity and charging speed. Most take around 4-6 hours to fully charge. If you know the charging time for your specific model, you can check the time to see if it has been fully charged.
- Use a voltmeter: A voltmeter can be used to measure the voltage of the power bank. When it is fully charged, the voltage should match the manufacturer’s specifications.
Do I need to charge the power bank longer for the first time?
The charging time can vary depending on the capacity and charging speed, but there is generally no need to charge it longer for the first time.
It’s important to follow the manufacturer’s instructions, which may include recommendations for the initial charge. Some manufacturers may recommend fully charging the power bank before first use, while others may indicate that the device is pre-charged and ready to use right out of the box.
Can I charge my phone via a power bank that is still getting charged?
It depends on how much charging power your phone uses compared to the charging power of the power bank. If the charging power is not the same, you may notice that one or the other device is even discharging.
How long does a power bank last?
If you take care of it properly and always store it in a cool and dry place after each use, it can last for several years. In case you use it multiple times every day, the battery performance will eventually degrade the same as the batteries on other devices.

In this review, we have thoroughly examined the various aspects of the affordable 20000mAh power bank to meet the specific needs of potential buyers like you.
