Attention:
1. Please read the description carefully before use. Please be aware of your surroundings when operating.
2. Please take precautions. When doing experiments such as burning and reagents, please wear protective equipment such as goggles and gloves to avoid burning your skin and clothing.
3. Minors should purchase and use this product under the supervision of a guardian.
4. Do the follow-up finishing work after the experiment. Keep the lab kit out of reach of children.

Read Before Purchasing:
- The product has a built-in coulomb meter. The coulomb counter is programmed, and the default setting is 21700 for 4800mAh, with a total of 8 batteries.
- The protective film of the acrylic transparent shell of the product (transparent version) cannot be restored once torn. In the event of a return, the associated enclosure fee will be charged.
- Users should not disassemble the finished product. Once the product is disassembled, the warranty is no longer provided.

Coulomb Meter Calibration Steps:
First, fully charge the power bank and charge it to less than 3W input power. It is then discharged at medium power (within 50 watts. Within 30 watts recommended) until the discharge reaches the protective plate protection function, i.e., a capacity calibration learning is completed.

Product Function Introduction:
It is a newly upgraded 200W high-power power power bank. This product is a brand new solution based on the old model.

The old 200W power bank uses one IP6559 and one sc8812. However, due to the compatibility issue of SC8812, sometimes some chargers cannot be recognized. The upgraded 200W power bank replaces sc8812 with IP2368, improving the compatibility of the product.

At the same time, we have made a major upgrade to the coulomb counter. The new product adopts BQ4050 coulomb meter, which can accurately count the amount of electricity. At the same time, the voltage of each battery is also more accurate, and there will be no frequent refresh changes.

Features:
- 200W Two-way Fast Charging Power Bank: It supports many fast charging protocols, with a wide-angle IPS color screen and a built-in coulomb counter.
- 1.54" IPS Screen and Stable System Make It Smooth to Use: The product adopts AT32F403ACG main control, and the screen is a 1.54-inch wide-angle IPS color screen. The system is stable, and the possibility of crashing is almost non-existent. The product supports automatic wake-up of output and input. Users can also manually wake up the power bank by pressing a button.
- DC Interface: There is a DC interface next to the switch button, and the size is 5.5*2.5mm. The interface is connected directly to the batteries, so the output voltage is equal to the battery voltage. Users can directly see the output current of this DC port on the screen, and they can also see the power. If you use it to charge a power bank through this interface, you will need a 16.8V 4-string dedicated charger. If it is charged through this DC port, then the two type-C ports will support continuous output, and this power bank can be used as a desktop charger or UPS power supply.
- Type-C Ports (C1 and C2): C1 and C2 support up to 100W, and USB supports up to 36W. It should be noted that C2 and USB share the same circuit. Therefore, C2 and USB are not recommended to output at the same time. If they output at the same time, it is only 5V 2A. C1 is a 100W bidirectional charging and discharging port which can be used for both charging and discharging.
- Convenient to Install Batteries: The batteries of the product do not need to be welded, and only a few screws are needed to fix the batteries. It is simple and convenient to install the batteries. And the batteries can also be quickly replaced if they are damaged.
- Fast Charging Protocols: It supports many fast charging protocols.
- Small Size and Large Capacity: With a compact size and a large battery capacity.

Precautions:
- Because of the high temperature in summer, the black shell of the product is more absorbent, so please do not use the product directly in sunlight.
- Please be careful not to drop the product to prevent accidents, because the battery power and capacity of the product are relatively large.
- The protective film of the acrylic transparent shell of the product (transparent version) cannot be restored once torn. If the return is made, we need to charge the shell fee.
- It is normal for the battery voltage to be unbalanced during charging and discharging. Once the plug is removed, it is back to normal.
- When you receive the product, the % of the battery may be displayed abnormally when it is first charged and discharged. For example, if the charge reaches 80%, the product cannot be charged. At this time, it depends on the total battery voltage. When the voltage reaches 16.8V, the product has reached the maximum voltage. If you want the capacity to be displayed normally, you need to follow the capacity learning steps above.
- The capacity of the product is as high as 40000mAh, and the capacity of most mobile phones is about 4000mAh. The difference in capacity between the two is 10 times. Therefore, the time taken by a charger to charge the power bank will also be several times longer than that of a mobile phone. Some inferior chargers cannot work at full load for a long time, which can easily lead to damage to the charger. For example, when our power bank is fully discharged and it needs to be fully charged, a charger to output 1.5 hours at full power 100W is needed. If the charger comes without temperature protection, it is very easy to cause damage. As long as our power bank can be used normally after changing the charger, then the power bank has no quality problems. If there is something wrong with your charger, please contact the relevant merchant to solve it.
