1.Product Introduction
(1)Module Introduction
Charging module is a project for the Internet of Things and renewable energy, providing safe and efficient embedded solar power management modules for makers and application engineers. The charging module has the function of solar energy charging, which can use solar energy to charge lithium batteries under certain light conditions, and has the function of power protection, providing efficient and reliable power management for various solar energy projects.
Application reference: solar car and robot, solar intelligent environment monitoring system, small solar street lamp.
(2)Interface Description
Charging module is a module used for charging lithium battery with a standard voltage of 7.4V and a full voltage of 8.4V in double section series state.
The charging module contains two 5.5X2.1mm power block DC power ports, which can input power to the lithium battery and to the controller board.
A Type-C interface to connect the charging head (not more than 5V) input power.
A solar panel connector to connect the solar panel input power supply.
An LED display light to display the charging status.

4.Test Result
The charging time of lithium battery is affected by major factors such as battery capacity, charging current, battery voltage, charging method and battery life. Therefore, the charging time parameter of the lithium battery is only used as the reference time in the test environment conditions, and the actual charging time may have a certain deviation. Therefore, the charging module will have different charging times due to different charging modes. The specific cases are as follows:
(1)Adapter Charging
It takes about 1 hour and 42 minutes to charge two 18650 batteries (capacity 4800 mAh) with 5V / 2A to 75% and about 5 hours when fully charged.
Attention: Adapter specification must be less than 5V voltage.
(2)Solar Charging
On a sunny day, it takes about 3.5 hours to charge the 18650 battery (capacity of 4800mAh) to 50% power state by solar energy. It takes about 12 hours to charge to 85% power state.
Attention: The solar panel must use 6V operating voltage, not exceeding 3W model.
(3)USB Charging
If you use the USB interface of the computer to charge the 18650 battery (capacity of 4800mAh) to 90% power state, it takes about 6 hours; When fully charged, it takes about 9 hours.
(4)The solar and adapter charge at the same time
If the solar energy and 5V/2A charging head are used to charge the 18650 battery (capacity of 4800mAh) at the same time under specific circumstances, it will take about 1 hour and 40 minutes to charge to 80% of the power state. When fully charged, it took about 4 hours and 50 minutes.

They are advertising the new Z Fold 8 ultra. We have the Z Fold 7, so we went there to check it out ans to buy a new mobile. I asked to see the phone because, in stores, they usually let you see and touch the phone before buying it. The guy replied in a really sarcastic way: “As I am the professional here, I can confirm that it is a good phone.” I was like: “What?” Then I showed him that I already had a Z Fold 7 in my hands. He replied: “So, you already know that it is a good phone.” Again, I was like: “What?” So I explained that I simply like to see and touch the phone before buying it. He just told me: “OK, go to a big store. We don’t have the phone here.” Well… not recommended. Even though I’m a big Samsung fan, I still want to check the phone for myself before buying it. It’s up to me. Expertise on something? ChatGPT also has expertise and will probably tell me much more than a sales guy.

Zero stars if I could. I purchased a fitness tracker from this store that failed to perform its most basic advertised functions. It would not reliably track steps, sleep, or heart-rate data, and the battery life was nowhere near what was claimed. When I returned to the store for assistance, I was told the device had been checked and was supposedly working correctly. However, the problems continued exactly as before. Despite the tracker clearly not functioning as expected, the store refused to offer a replacement or further assistance and instead told me to deal directly with the manufacturer. This is extremely disappointing customer service. When a product sold by a retailer appears to be defective, customers reasonably expect the retailer to help resolve the issue rather than simply pass responsibility elsewhere. The most frustrating part was not the faulty device itself, but the complete lack of support once the sale had been made. Based on my experience, I would strongly recommend that others think carefully before purchasing electronics from this business, especially if after-sales support and customer service are important to them.

The staff were really helpful and they knew a lot about their products. 10/10 I'd definitely recommend this store. Also, it is the only place in St. Paul's Bay selling Kodak, Polaroid cameras and digital cameras.
