Technoamp JNS 200W 40000mAh DIY Power Bank 21700 USB C PD3.0 PPS 100W Quick Charge 3.0

Product Description

1. The newly upgraded 200w high-power mobile power supply. IP2368 chip that greatly improve product At the same time, we use bq4050 coulomb meter, which can accurately count the electricity. At the same time, the voltage of each section is more accurate battery percentage
2.1.54 inch wide angle IPS color screen displays various data in real time. The product adopts AT32F403ACG master control, and the screen is 1.54 inch wide angle ips color screen. The system is stable and there is almost no possibility of crash. The product can be output and input to automatically wake up, or can be manually wakened by pressing the key.
3. The solderless structure battery box is more convenient to install the battery. The battery assembly does not need to be welded and does not damage the battery. It only needs a few screws to fix it. It is simple and convenient. It can also be replaced quickly after damage.

The spare parts can be installed with 21700 batteries or 18650 batteries. The spare parts are universal. The 18650 spare parts will have one more installation accessory, and the 21700 spare parts will have one less. Therefore, we will send them according to the most accessories, so that customers can install both the 21700 and the 18650 battery, so installing the 21700 battery will have one more part.

Note to purchase: only 21700 batteries with diameter less than 21.5mm can be installed for spare parts. For example, Samsung, lg, Tesla, etc. Some domestic batteries are too large in diameter to be installed. If they are hard installed, they may cause damage such as skin breakage and short circuit. Such damage is of little repair value. Please use high-quality 21700 batteries!

Note: For the DIY kit without battery, the battery display on the display screen is 5000mah by default, so please use 5000mah battery during installation, and other capacity needs to be modified, which is $5 per time. In addition, the coulomb meter needs to be learned, and it needs to be repeated several times before it can display accurately.

The product has a capacity of up to 40000 mah, and most mobile phones have a capacity of around 4000 mah, with a capacity difference of 10 times. Therefore, the charging time of the charger for the charging bank will also be several times longer than that of the mobile phone. Some inferior chargers cannot work at full load for a long time, which can easily lead to damage to the charging head. For example, when the product is fully discharged and fully charged, it requires a charging head with a full power of 100w to output for 1.5 hours. If the charging head does not have temperature protection, it is extremely easy to cause damage. As long as the product can be used normally after changing the charger, there will be no quality issues with the product. Contact the manufacturer to resolve the charging head issue on your own.
Calibration steps for coulomb meters: First, fully charge to less than 3W input power, then discharge at medium power (within 50W, recommended within 30W) and place it on a protective board for protection, completing the learning of capacity calibration once

Note:
1: It is normal for the battery voltage display to be unbalanced during charging and discharging, and it can be restored to normal after unplugging the plug
2: When receiving the discharge for the first time, turning on% may indicate abnormal display. For example, if the battery is charged to 80%, it cannot be charged. At this time, depending on the total battery voltage, the voltage reaches 16.8V and the maximum voltage has been reached. If you want the capacity display to be normal, you need to follow the capacity learning steps on the details page to operate
