It is not easy to find a high-quality power bank, especially when there are a lot of fake reviews on Amazon or any other websites. I’ve tried a lot of the backup batteries but just a few of them could last until today.
The CHOETECH 20,000mAh power bank has some great features but how well it can hold the power? I’ve used the power bank in the last 4 months and here is the full review.
Unboxing & Testing
Features & Performance
The CHOETECH power bank is among the highest-capacity power banks I’ve ever used. It is very powerful with the 20,000 mAh battery inside. That means it can charge my iPhone up to 7-8 times. Therefore, you should expect the size is a lot bigger and thicker than most other backup batteries.
Another notable feature is that there is a lightning port to charge the power bank. This is extremely useful for iPhone users since you no longer need a micro-USB cable to recharge the battery itself. Just use the iPhone’s charger to charge the power bank, the process will take about 4-5 hours. Then you can use the lightning cable to charge your iPhone from the power bank.
The battery can hold the power pretty well. I left it unused for about 3 months and there is still about 50% left when I pick it up. Of course, there are still better-performing power banks, for instance, the Jackery almost didn’t lose any juice after resting for 4-5 months.
There are LED indicators on the front to show you the current battery level. The power bank is quite big since there is a huge battery inside. I’m a little disappointed as there is no built-in flashlight like most other products. There are 4 ports on the side, including a micro-USB port (input: 5V/2.4A, 9V/2A), a lightning port (input: 5V/2.4A), a USB port (output 5V/1A), and a USB port (output: 5V/3A, 9V/2A, 12V/1.5A). The fast-charging port has the blue color, it takes just about 1 hour and 30 minutes to fully charge my Samsung Galaxy S7 Edge phone. The other USB port is used for iPhones, a full charge of my iPhone 7 Plus takes approximately 3 hours.
The CHOETECH power bank is a good high-capacity backup battery for your phone. There are a few minor limitations but this is still a steal at this price.
