When looking for the best 20000mAh power bank there are a few important features to consider other than the actual capacity of the battery pack. This really depends on your portable charging requirements. If you need to charge a couple of tablets or iPads at the same time, then the best 20000mAh power bank will be the one with the biggest max output. If you want to minimize the recharge time, then a Quick charge 3.0 power bank with a suitable QC 3.0 wall adapter would be the preferred option.
If you need some help understanding more about the specifications and features found on high capacity power banks, there’s a short guide at the bottom of the post.

Need help choosing the best 20000mAh power bank ?
If you are looking to buy a high capacity portable battery charger but are unsure of which specifications or features are important here’s some info that may be of help.
- Capacity – Measured in mAh’s (milliampere-hour) is basically the amount of storage the power bank has. This amount is just a guide, the actual amount the battery delivers is dependent on its efficiency. This can be anywhere from 70%-85%. If you are charging a phone with a battery size of 2000mAh with a 20000mAh power bank, you’d get 10 full charges if it was 100% efficient (this will never happen). In reality, you are far more likely to get 7-8 charges.
- Pass-through charge technology – This allows you to plug devices into the power bank as it’s being recharged. On high capacity power banks, this feature is extremely useful and not often seen.
- Max Output – This refers to the overall output of the power bank. Typically more important on a high capacity portable charger, when recharging multiple devices at the same time. If your Smartphone requires 1A and your tablet requires 2.1A then a power bank with a 3.1A Max output would be sufficient. If you were then to plug in a third device, the 3.1A would be shared, and the recharge time would take longer.
- Additional Technology – Each power bank will have it’s own terminology, Anker call theirs ‘PowerIQ‘, RAVPower use the name ‘iSmart‘, Zendure has ‘Zen+‘ and the list goes on. There are some variables depending on the manufacturer, but in general, this relates to an adaptable output from each USB port. When you plug in a device, the power bank will identify it’s maximum recharge speed and deliver the correct amount of power.
- Safety Systems – Most, if not all power banks will offer protection against short-circuits, over-current and overloads. Usually, the power bank will shut off and will require you to connect the charging cable to reset the system.
- Battery Quality – This is something that you will need to consider. It’s hard to know about the quality of the Lithium battery inside without cracking the power bank open and having a look (not advisable). Generally speaking, if it’s ridiculously cheap it will likely be of a poor quality. My advice is to choose a recognised and trusted brand that has some control over their own R&D. There are so many companies attaching brand names on generic OEM power banks and selling them cheaply. Portable charging devices like the Zendure A-Series power bank do cost more, but it’s for a good reason. – back to list
