How to Choose a 20,000 mAh Power Bank - Buying Guide
Here are some key points to consider:
- Consider the number of ports for simultaneous charging.
- Opt for a higher maximum output for more power.
- Inspect the maximum input to determine charging time.
- Check the life cycle of the battery to know how long it will last.
- Choose a power bank with the right size and weight for portability.
- Look for additional technology and features that offer more value.
For more information, read through our buying guide below.
Consider the Number of Ports for Simultaneous Charging
A typical 20,000 mAh power bank has one to two ports. However, if you want a heavy-duty portable battery to charge your devices simultaneously, consider buying one with three to four ports. Choosing the latter is especially convenient for those who bring multiple devices with them.
Just take note that a power bank with more ports is generally bulkier and heavier than the typical two-port device, which is slender and more lightweight. Moreover, some portable power banks can support up to five ports, but they are more expensive but definitely worth every peso if you have multiple gadgets.
Opt for a Higher Maximum Output for More Power
Check the maximum output so you would know its capacity to charge devices simultaneously. As you compare 20,000 mAh power banks, you will notice varying maximum output like 5V/3A 9V/2A 12V/1.5A or more. There are even juicier power banks with 45W and 60W max output, sufficient to charge a laptop.
Most buyers think that the higher the maximum output, the better. But you must also consider the type of devices you are using for faster and more efficient charging time. For example, an iPhone requires 1A max output while an iPad has 2.1A max output. Thus, if you plug them into a power bank with 3.1A max output, that's already enough.
However, if you add another device to the port, let's say another iPad, the 3.1A max output is shared by these devices, resulting in longer charging hours if you plug them simultaneously. To put it simply, a higher max output indicates that it can fully charge your devices more than once.
Inspect the Maximum Input to Determine Charging Time
When you buy a power bank, check the input voltage to determine how fast you can juice it up. Ideally, you should go for 5V 2A or more for fast charging. Generally, it will take about 5 to 11 hours to charge a 20,000 mAh in full for as long as you plug it with a compatible USB-C input cable and charger.
Some brands advertise shorter hours if you use unique superchargers with 60W or more. These are sold separately, but they have high voltage and amperes to speed up the charging hours. Meanwhile, some power banks don't come with a USB-C input cable, leaving users with no choice but to use a standard USB cable that may take a while to recharge the power bank due to its low amperes.
Check the Life Cycle of the Battery to Know How Long It Will Last
Most premium power banks have either lithium-polymer or lithium-ion batteries, but just like any battery, they also wear out, losing their charging capacity. That said, these power banks have life cycles. The count starts at zero for brand new devices, and as you charge the power bank over time, the cycle count also increases.
The typical cycles of batteries last from 200 up to 1,000, depending on the quality and frequency of use and charging. So when you choose a power bank, inspect the battery life cycle to know how many years you can use it. In general, a power bank that is properly used and charged can last for several years.
There are also 20,000 mAh power banks sold at a lower price but have shorter life cycles. That being said, it is better to buy a power bank in the medium price range of PHP1000 to PHP2000, so you get to use it for a longer time than buying an affordable one once in a while.
Choose a Power Bank With the Right Size and Weight for Portability
As the capacity of power banks increases, so do their size and weight. You should expect that a 20,000 mAh power bank is hefty and bulky, weighing anywhere between 350 to 450 grams. But because power banks are usually hand-carried or placed in a bag, it is ideal to get one that has the least amount of weight possible for portability, so you wouldn’t feel burdened if it is heavy.
Another factor is its dimensions or shape, which is often rectangular with a median length, width, and thickness of 140 mm, 70 mm, and 20 mm, respectively. Knowing the size is equally important to ensure that the power bank fits perfectly inside your bag so that when you arrange your things, you can adjust accordingly and have ample space for it.
Look for Additional Technology and Features That Offer More Value
Having a solar 20,000 mAh power bank that makes it easier to charge with sunlight is ideal for those who love to hike and camp out. Another convenient feature is a small LED screen or light indicator that displays the battery level for you to know how much juice it has left.
Some power banks even have built-in cable, so you don't have to use a USB charger. All you need is to connect the socket to the outlet, and you're good to go. Moreover, if you're using a premium smartphone that supports wireless charging, you're in luck as there are already power banks that feature this technology.
As you compare the power banks, it is also best to check if it is quick charging, preferably armed with Qualcomm Quick Charge technology that speeds up the charging up to zero to 50% in five minutes. Lastly, see if it has a chip or circuit protection that allows you to charge the power bank and, at the same time, plug another device without overheating or harming the battery life.

Frequently Asked Questions
Below are some of the most asked questions on the web answered by the mybest team.
Is a 20,000 mAh Power Bank Allowed In Flight?
Yes. 20,000 mAh power banks are allowed in flight as long as they are stored with your carry-on luggage. Bringing a power bank on a plane is alright, given that it is 27,000 mAh or less. However, note that since power banks are considered batteries, they are flammable and can be dangerous if ever they explode, so ensure that they are stored properly in a sealed container.
How Long Can I Use a 20,000 mAh Power Bank?
The longevity of a 20,000 mAh power bank depends on your device’s milliamp-hour or mAh. For example, if your phone requires 3000 mAh to fully charge, divide it from 20,000 mAh to get a rough estimate of how long your power bank will last. The number you get from the computation tells you the number of charges the power bank can sustain.
What to Do When Power Bank Overheats?
Devices and gadgets slightly heating up when used non-stop or charged are normal occurrences. This is the same case as with power banks. But if the power bank becomes hotter than usual, immediately remove the devices being charged or disconnect it from its charger. Afterward, leave the power bank in a cool and well-ventilated area, preferably outdoors, until it cools down.
