Don't inversely connect,it will result in burning of board.Make sure there is insulation between power and circuit when install the battery2. Press and hold the switch,flashlight LED light starts,then press and hold to turn it off3. 2A output is not continuous current,it changes according to USB connecting load, automatic current output as per load4. If battery is connected incorrectly, the reverse polarity will burn the circuit.So, make sure to check the battery polarity when connecting.Special Instruction:When connecting the board for the first time, connect the battery and then connect the micro USB charger and charge the battery to full capacity before using.It is required to prime the IC, so that it starts and shuts down accuratelyNote:Please allow 1-3mm error due to manual measurement.Due to the difference between different monitors,the picture may not reflect the actual color of the item.Package Includes:1x Power Bank Charging Board Review: Waste - Waste ## Features - Input Voltage: 5V | Input Current Rating: upto 2.5A | Input Interface:Micro USB | Can use any mobile power supply rated 5V - Output: 5V 1A | Output Interface: Dual USB output - 4 onboard SMD LED to display battery charge level - Separate 5mm LED to use the power bank as a torch - Overcharge protection | Overdischarge protection | Overcurrent protection ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09RH1B2Y2 | | Brand | CentIoT | | Compatible Devices | Smartphone | | Compatible devices | Smartphone | | Connector Type Used on Cable | usb | | Connector type | usb | | Cooling Method | Air | | Current Rating | 2.5 Amps | | Customer Reviews | 1.0 out of 5 stars 1 Review | | Item Dimensions | 6.8 x 2 x 0.6 centimeters | | Manufacturer | CentIoT® | | Maximum Input Voltage | 5 Volts | | Mfr Part Number | BM073-5V1A-HT4936A | | Minimum Input Voltage | 5 Volts | | Model Name | BM073-5V1A-HT4936A | | Model Number | BM073-5V1A-HT4936A | | Model name | BM073-5V1A-HT4936A | | Output Wattage | 5 Watts | | Output wattage | 5 Watts | | Unit Count | 1 Count | | Wattage | 12 watts | ## Product Details - **Brand:** CentIoT - **Compatible devices:** Smartphone - **Connector type:** usb - **Model name:** BM073-5V1A-HT4936A - **Output wattage:** 5 Watts ## Images ![CentIoT - HT4936A Power Bank Charging Module Circuit Board - 5V 1A Dual USB - Image 1](https://m.media-amazon.com/images/I/51nqILMSy5L.jpg) ![CentIoT - HT4936A Power Bank Charging Module Circuit Board - 5V 1A Dual USB - Image 2](https://m.media-amazon.com/images/I/61iUZDGvoWL.jpg) ![CentIoT - HT4936A Power Bank Charging Module Circuit Board - 5V 1A Dual USB - Image 3](https://m.media-amazon.com/images/I/61dwZ9wIGSL.jpg) ![CentIoT - HT4936A Power Bank Charging Module Circuit Board - 5V 1A Dual USB - Image 4](https://m.media-amazon.com/images/I/61CcDZfu4rL.jpg) ![CentIoT - HT4936A Power Bank Charging Module Circuit Board - 5V 1A Dual USB - Image 5](https://m.media-amazon.com/images/I/61RIJkspe8L.jpg) ## Customer Reviews ### ⭐ Waste *by D***. on 2 February 2025* Waste ## Frequently Bought Together - CentIoT - HT4936A Power Bank Charging Module Circuit Board - 5V 1A Dual USB - Generic ESP8266 Nodemcu Esp8266 Lua Amica Wifi Internet of Things Development Board Cp2102 Iot - REES52 HiLetgo HiLetgo New Version NodeMCU LUA WiFi Internet ESP8266 Development --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/589591688-centiot-ht4936a-power-bank-charging-module-circuit-board-5v-1a](https://www.desertcart.pt/products/589591688-centiot-ht4936a-power-bank-charging-module-circuit-board-5v-1a) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-21*
