The comments that state they put the battery in wrong and it caught on fire.... Learn from others mistakes and double check that positive and negative are aligned correctly, also use flat top batteries and the fit is perfect. I had a longevity test running and it has not turned off a single time in over an hour until the battery could no longer power the LED strip. The case comes with a USB C input which isn't mentioned, but very welcome as I don't like using USB mini. There are 5 red LEDs to indicate power level of the battery while being used and while charging. As I was using this to power a 6ft strip of LEDs, I don't think they affected power levels to any significant degree. Suggest making sure you purchase a higher mAH battery so that it will last longer between charges. Typical I have seen is 3000 but found one that's 9900 I will be trying out. Review: Useful little gadget. Has USBC port. - I got this item to test capacity of recycled 18650 cells. Combined it with a USBC power meter and an old phone as load. Seems to work OK. Manufacture was less impressive - see photo of poor surface mounting. ## Features - Micro USB Port Input: Features a convenient Micro USB port for easy charging of the battery module - Type-A USB Output: Equipped with standard Type-A USB output port for connecting and charging your devices - Switch Control USB Output: Includes 1 switch control for managing USB output power on demand - Over Charge Protection: Built-in safety feature prevents battery damage from overcharging during use - Over Discharge Protection: Integrated protection system safeguards battery from over-discharge to extend lifespan - Multiple Output Options: Provides 3V at 1A and 5V at 2A output with 3 ports for each voltage level - LED Charging Indicator: Green LED indicates full charge status while red LED shows active charging process - 18650 Battery Holder Design: Compatible with standard 18650 lithium-ion batteries for portable power bank applications ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0784FPF8J | | Amperage | 0.5 Amps | | Antenna Location | Indoor | | Battery Cell Type | Lithium Ion | | Brand | diymore | | Built-In Media | battery holder | | Customer Reviews | 3.9 3.9 out of 5 stars (112) | | Item Weight | 25 Grams | | Manufacturer | diymore | | Model Name | diymore Li-ion Battery V3 Shield | | Model Number | A1012590US | | Reusability | Rechargeable | | Unit Count | 1.0 Count | | Voltage | 3 Volts | | Warranty Description | no | ## Product Details - **Battery Cell Composition:** Lithium Ion - **Brand:** diymore - **Recommended Uses For Product:** Indoor - **Unit Count:** 1.0 Count - **Voltage:** 3 Volts ## Images ![diymore Li-ion Battery V3 Shield 1 Holder 3V/1A 5V/2A USB Power Bank Battery Charging Module 18650 Battery Holder - Image 1](https://m.media-amazon.com/images/I/61znE2R-YxL.jpg) ![diymore Li-ion Battery V3 Shield 1 Holder 3V/1A 5V/2A USB Power Bank Battery Charging Module 18650 Battery Holder - Image 2](https://m.media-amazon.com/images/I/61RcTihvYZL.jpg) ![diymore Li-ion Battery V3 Shield 1 Holder 3V/1A 5V/2A USB Power Bank Battery Charging Module 18650 Battery Holder - Image 3](https://m.media-amazon.com/images/I/71ZcwxtLaeL.jpg) ![diymore Li-ion Battery V3 Shield 1 Holder 3V/1A 5V/2A USB Power Bank Battery Charging Module 18650 Battery Holder - Image 4](https://m.media-amazon.com/images/I/61YddBlm3JL.jpg) ![diymore Li-ion Battery V3 Shield 1 Holder 3V/1A 5V/2A USB Power Bank Battery Charging Module 18650 Battery Holder - Image 5](https://m.media-amazon.com/images/I/61+CG84wydL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: Could i use this as a ups for a raspberry pi?** A: From what I could tell on my board it has a delay of about 5-10 seconds from off to on. When unplugging the charging cable from the battery pack from both the usb powered option and the 5v. **Q: What is the inside length of the battery housing? I want to use a protected 18650 cell with a 68.9mm length.** A: Hi friend, the 68.9mm is too long for the housing. **Q: Can someone clearly explain how this device works and its features? The instructions/manual is garbage and impossible to understand. Thank you.** A: Slide -Switch appears to have the following use: My V8 (dual-cell) unit has the slide switch (not labeled) and the push-button. Orient the board so you can see LED's and read stencil graphics, then switch is on the bottom-left of card. (a) slide-switch LEFT ("position closest to the short-edge of the board") == AUTO power-down mode == unit will turn-off when there is nothing taking power from the USB port. (b) slide-switch RIGHT ("position further from the short-edge of the board") == MANUAL == unit will remain ON until turned off or batteries too low. My unit does not auto-power up, but a single press of the button turns it ON, and double-press of the button turns it OFF. Triple-pressing the button only glitches the power off/on and does not affect the LED's unlike what someone answered here. **Q: can i hook a batterie bank to this to give this power? and dose it work with out the cells in it if i just have a batterie bank hooked to it?** A: Treat this module as a standalone power pack. You need two 18650 batteries. Interestingly, Amazon sells some flashlights that include the batteries and a charger. It's a great investment. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Cost effective rechargeable battery shield *by J***A on June 16, 2024* This battery shield will become a staple in future projects.
