KEHIPI DC Buck Converter 9V-36V to 5.2V 3.5-6A Blue
Steps down 9 V–36 V DC to 5.2 V with USB output, delivering up to 30 W at lower input voltages
- TypeBlue/1pcs
- Weight0.018 kilograms
- Wide 9 V–36 V input suits varied power sources
- Synchronous rectification delivers high efficiency across the range
- USB port with quick-charge chip powers phones directly
- DC jack plus terminals simplify wiring for any device
- Compact 63×27×10 mm board fits tight enclosures
Compact DC buck converter for 5 V USB devices
This step-down module accepts a DC input between 9 V and 36 V and delivers a regulated 5.2 V output through a USB port and screw terminals. It is aimed at hobbyists, installers and anyone powering phones, tablets or small 5 V loads from a higher-voltage source such as a vehicle or industrial supply.
Fits into a build with DC terminals and USB output
The board measures 63 mm by 27 mm by 10 mm and weighs 22 g, so it sits easily inside enclosures or behind panels. Synchronous rectification keeps efficiency high across the input range, while the DC jack, terminal block and USB socket give multiple wiring options without extra adapters. Quick-charge identification allows compatible phones to negotiate faster charging.
Output current falls as input voltage rises
At 9 V to 24 V input the converter supplies up to 6 A (30 W). Between 24 V and 32 V the limit drops to 5 A (25 W), and from 32 V to 36 V it falls further to 3.5 A (18 W). Designers must size the source and cooling for the lowest current band that matches their actual input voltage.

Questions about this item
What is the maximum continuous output power before the 30 W limit at 9-24 V input drops to 25 W at 24-32 V?
The converter delivers 30 W (5.2 V / 6 A) from 9-24 V input, then 25 W (5.2 V / 5 A) from 24-32 V, and 18 W (5.2 V / 3.5 A) from 32-36 V.
How much heat must be dissipated when running at the 30 W rating all day?
At 9-24 V input the synchronous rectification design achieves high efficiency, so only a fraction of the 30 W becomes heat; the compact 63×27×10 mm case relies on natural convection.
Which input connector must my power source provide to use the DC terminals?
The module accepts a bare-wire DC input range of 9-36 V through its screw terminals; no specific barrel jack or proprietary plug is required.
