KEHIPI 5V-11V to 12V 3A 36W Step-Up Power Adapter
Boosts 5V–11V DC input to 12V at 3A with over 93% efficiency in a rugged aluminium case
- Product type5 V to 12 V 3A
- Product colorSilver
- Product weight0.22 lb (0.1 kg)
- Converts 5 V to 11 V input into stable 12 V output
- Delivers up to 3 A continuous current at 36 W
- Over 93 % conversion efficiency reduces heat loss
- Waterproof, dustproof and shockproof aluminium housing suits harsh environments
- Built-in over-current, overheat and instant high-voltage protection
Purpose and fit
The KEHIPI step-up converter accepts a DC input between 5 V and 11 V and delivers a fixed 12 V output at up to 3 A for 36 W continuous power. It suits installers who need to run 12 V gear such as car stereos, radios or LED displays from a lower-voltage source in vehicles, solar setups or industrial equipment.
What the bundle changes
A single module ships with 13 cm to 14 cm flying leads — red and black on the input side, yellow and black on the output — so the unit can be wired directly without extra connectors. The aluminium shell provides waterproof, dustproof and shockproof sealing plus passive cooling, letting the device survive harsh environments without a separate enclosure.
Capacity and limits
Efficiency exceeds 93 % across the input range, and the converter operates from -40 °C to +85 °C. The 36 W ceiling means loads above 3 A at 12 V will trip over-current or over-temperature protection, so it cannot support higher-power amplifiers or multi-device arrays. The 66 mm by 60 mm by 22 mm footprint fits tight cavities but offers no headroom for future expansion.

Questions about this item
Does the aluminium shell need any periodic maintenance such as cleaning or re-greasing?
The aluminium housing is sealed and rated waterproof, dustproof and shockproof, so no routine cleaning or lubrication is required.
What is the first limit reached when the converter runs continuously at full load?
The continuous output current is capped at 3 A, so the 36 W power limit is reached before any thermal threshold under sustained use.
How much heat and noise does the unit produce when it operates all day?
Efficiency exceeds 93 % and the aluminium case provides passive cooling, so heat stays low and there are no moving parts to generate noise.
