5. EC Technology Portable Charger 20000mAh Power Bank

EC Technology Portable Charger Power Bank 22400mAh

  • By: EC Technology 20000mAh Power Banks

EC Technology decided to bypass the 20000-mAh power rating and made one with even extra power. We chose to put it in this review because it has a reasonable price. You can research and see there are even more power banks with lower capacities that are more expensive. There are also more reasons for it to be on this list like the excellent auto IC technology. What this means is that with the three ports in it, they adapt to the device you are charging.

To expound, if your device has an input power rating of 1 ampere, this is exactly what it will get. If your device has a fast charging capability, it is powered with that rating automatically. We cannot understate how important it is to get this right. When you charge a low power rated device with a fast charger, you may think that you have hit the jackpot. Yes, it will charge fast, however, in the end, it will perform terribly. Let us just say you kill the cell a little bit every time you do this. Therefore, if you have different power rating devices, we highly recommend getting this, for your own good.

  • Detects and delivers optimal charge.

Let us say you have a phone with a charging input of 2 Amperes. If you put it in a charge of one ampere, it means you will charge it twice as long. This is certainly not what the manufacturer or you want to happen. With two adaptive outputs, you can use two devices with different or equal power ratings, and still get the best charge output possible.

Extra reasons why I picked Best 20000mAh Power Banks:
  • AUKEY provide a 45-day money back guarantee.
