Compact and efficient, each module supports 3.7V-4.2V 18650 batteries with built-in overcharge protection and LED indicators, making it ideal for powering DIY electronics, Raspberry Pi projects, and portable devices with reliable, safe, and customizable power management. ## Description Technical specifications: Charging voltage: 4.2V DC Charging current: Max. 1A Discharging current: Max. 2A the output current: 5V 1.4A/9V 0.8A/12V 0.6A Input voltage: 4.5 - 8V DC Output voltage: 4.3 - 27V DC (Continuously adjustable) Size: 1.3 in x 0.92 in/33 mm x 23 mm Package Includes: 2 * Buck Converter Module Review: Does what it says - Used a few of these, still trying to find another project or 2 to use them in. Use 2 to power 2 separate raspberry pi nodes for hamvoip with a transmitter. Set to about 6 volts these are powering the pi and transmitter without issue. I'm running them off some salvaged 18650s. Seems to be of good quality, voltage is stable and handles the amp load while transmitting around 1.5 amps in total. Charger seems to have working overcharge protection. I'm not sure how long I left this on for, but I did add an on/off switch between the board and battery as well as the pi project. I'm not sure what the continuous draw is but there is one. I left a pi off for a few days but board directly connected to my battery and I noticed it did not last as long as previous runs. It WILL drain your batteries if not charging. Review: Great project board - So many awesome features here! 1. Accepts a wide range of DC input for charging 2. Provides and adjustable DC output (the adjuster is sensitive, but hitting 5V is pretty easy) 3. LED for charging status 4. Automatic shutoff at around 2.8V (requires 6-8V input to get the board to wake back up again) All for like $2 a board. I used this on a project where I powered a small drone camera VTX using a 400mAh battery. Worked awesome. ## Features - Material: Battery charger module made of electronic components.Can be used for multimeter, converted to lithium battery charging - Features: Battery charger module combines the TP4056 battery charger with a boost circuit.

Worked awesome. ### ⭐⭐⭐⭐ Works great with some modifications *by P***E on July 6, 2025* I am using this module embedded inside an ESP32-based project I am working on, where the LEDs would not be visible. I desoldered the LEDs and the resistors, then drilled two holes 2.54mm apart where the resistors had been. I then stuck a pin header through and soldered it so I could run the signals to the ESP32. They are open-collector outputs, so I can use pinMode(pin, INPUT_PULLUP), and digitalRead will return LOW when they are active. For monitoring the battery voltage, I used a 33k/47k ohm voltage divider and connected it to one of the analog inputs. The only issue is that there is no protection against discharging the battery too much. The boost converter is an SDB628, which cuts off under 2 volts, but Li-Ion batteries should not go below 3.2V. I built a circuit that would allow the ESP32 to cut off power when the voltage drops too low. ​ I like that it has an adjustable output voltage. It's a little fiddly to tweak because you have to use a voltmeter and a non-conductive screwdriver, but it only has to be set once. ## Frequently Bought Together - 6 Pcs Battery Charger Module USB TP4056 3.7V 4.2V to 9V 5V 2A Charge Discharge Integrated Step Up Module,18650 Lithium Li-ion Battery Charger Module - 15pcs 5V 1A TP4056 Charging Module Type-C USB 18650 Lithium Battery Charger Board with Protection (Type-C USB) - HiLetgo 10pcs 18650 Battery Clip 18650 Battery Holder 18650 Batteries Case for 18650 Battery with Connect Lead --- ## 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.id/products/389220412-6-pcs-battery-charger-module-usb-tp4056-3-7v-4](https://www.desertcart.id/products/389220412-6-pcs-battery-charger-module-usb-tp4056-3-7v-4) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-09*
