12V To 5V 3A 15W DC-DC Step Down Converter DC Power Supply Module Waterproof US

10/08/2026

12V Input to 5V Output 3A 15W DC-DC Step-Down Power Converter DC Power Supply Module Waterproof This 15W DC-DC converter converts a 12V input voltage (will operate with any input voltage from 8V to 24V) to 5V DC output at up to 3A. The module is epoxy sealed in a waterproof plastic housing with mounting tabs that can be used to mount the converter to a mounting plate, panel or bulkhead. Specifications: Epoxy sealed waterproof housingLightweight, compact, convenient to use and transportNon-isolatedWith overload / over-current / over / low voltage protection, stable performanceAuto recoveryInput voltage: DC 12V nominal, will operate on any input voltage from 8V to 24V DCQuiescent input current (no load attached): 96%Size (L x W x H): 38 * 27 * 23 mm (Length including mounting tabs is 52mm)Weight: 30gCase color: White Cable length: 12cm (approx)Operating Notes:As with any DC-DC converter, the input DC power supply powering this converter must be capable of providing the maximum power drawn by your load. If the input supply is not capable of providing the power, the converter will fold back the output voltage as necessary. Example: If your load draws 3A at 5V (15W), and the input supply is only capable of providing 12V at 1A (12W), the maximum output voltage the converter will deliver is 4V (12W/3A). The inputs and outputs are labeled on the sticker on top of the converter, the red and black wires are the + and – 12V input, and the red and yellow wires are the + and – 5V output. Package Includes:1x (1 piece) 12V Input to 5V Output 3A 15W DC-DC Step Down Power Converter Get it faster! Stocks and ships from our US Colorado office for quick delivery.

Adjustable non-isolated DC buck voltage regulator, incredibly small module 17x11x3.8mmGreat for LED lights, micro-controllers, battery chargers, and most other low power devices.Input: 4.75-23V, Output:1.0-17V, 3A Peak / 1.8A SustainedEfficiency: Up to 96% (depends on the difference between input and output voltage) This module uses synchronous rectification, the most efficient power conversion available.340KHz switching frequency, <30mV ripple (no load), MP2307 ICThe ultra-small Mini360 buck step-down voltage regulator is surprisingly powerful for it's size. Synchronous rectification is more efficient and creates less waste heat which allows it to reach current ratings found in regulators many times it's size. Despite the small size and low price, this power regulator delivers on it's specs. The output voltage is adjusted with the on-board potentiometer. Compared to the MP1584, this module offers smaller size, higher operating efficiency, and a higher sustained load rating, but with less pads and tighter input/output voltage ranges. Be careful not to exceed the input voltage or maximum output current. Do not back feed power through the module. Do not apply reverse polarity voltage.Adjustable non-isolated DC buck voltage regulator, incredibly small module 17x11x3.8mmGreat for LED lights, micro-controllers, battery chargers, and most other low power devices.Input: 4.75-23V, Output:1.0-17V, 3A Peak / 1.8A SustainedEfficiency: Up to 96% (depends on the difference between input and output voltage) This module uses synchronous rectification, the most efficient power conversion available.340KHz switching frequency, <30mV ripple (no load), MP2307 ICFast shipping from USAOrders under $10 ship without tracking

2pcs TP4056 5V 1A Micro USB 18650 Lithium Battery Charging and Protection Board

10/08/2026

Dual Function: 1) Charge lithium cells from a 5V power source 2) Protect battery from over-discharge and over-currentCharge input: 5V DC • Maximum charge current: 1000mA • Charge cut-off: 4.2VDischarge protection cut-off: 2.5V • Over-current protection cut-off: 3AMicro-USB input • Size: 2.6×1.7cmThis is an enhanced USB-powered module for charging rechargeable lithium batteries using the constant-current/constant-voltage (CC/CV) charging method.This module provides constant-current/constant-voltage (CC/CV) charging, along with protection against over-voltage, over-discharge, over-current and short circuits to protect the battery and the device that it is powering.The device to be powered by the battery is connected to the module’s OUT+ and OUT- connectors and the battery is connected to the B+ and B- connections. When connected to USB power, the module provides up to 1A charge current until the battery is charged, then switches to a constant voltage mode to keep it charged.During use, if the battery voltage drops below about 2.4V, the DW01A protection IC disconnects the battery from the OUT connectors, disabling discharge to protect the battery from running at too low and self-destructing.When the module is then connected to USB power, it will trickle charge the battery to 2.9V (the over-discharge release voltage), at which point the charge current will be linearly increased to 1A maximum and the module will reconnect the battery to the OUT connections, allowing discharge of power from the battery to a connected load. Although the module cuts output power from the battery during an over-discharge situation, it still allows trickle charging of the battery to occur.The module also protects against overcurrent and short-circuit protection – it will cut the output from the battery if the discharge rate exceeds 3A or if a short-circuit condition occurs.This module is perfect for charging single cell 3.7V 1 Ah or higher LiPo cells such as 16550s and 18650s that don’t have their own protection circuit. It can charge two cells in parallel, however since the two cells share the charging current, they take twice as long to charge as a single cell.
