Ideal size: current transformer

It is (see photo). Used this to drop the voltage from my motorcycle battery to my garage door remote. The size is perfect as it is smaller than the remote and fits in a small weatherproof case. Very easy wiring.

Pros
  • Widely used in car devices such as LED display, hard disk player, MP3, DVD, GPS, etc.
Cons
  • Compatibility

Low Voltage Power Supplies

The device I was trying to power normally uses a 3V button cell. I hooked these up to my truck's electrical system and I only have 2.58v when the truck is running. The advertised 3V output would have worked fine, but 2.58V wasn't enough to power my device all the time.

Pros
  • Lightweight, compact, easy to use and carry; Auto-recovery
Cons
  • Only available in black

Works great in car Garage Door Opener Installation

I used this to power my truck's garage door remote. I hid this unit and remote control in the truck's ceiling, hooked it up to the battery terminals and placed the LED switch in the roof panel. Has been working great for about 6 months now.

Pros
  • All sealed container with epoxy and waterproof case; Not isolated
Cons
  • Some small things

Non-accurate buck device

All connected - not easy! - and found it wasn't the advertised 3V output. Even with a typical input voltage of 13.8V, I only output 2.1V. not enough to light up the LED headlights on my garden tractor which require 3V. Waste of my time and money. Not a happy customer. I will not bother to return an item that costs me more than I paid for. As another reviewer said, have a backup plan. Unfortunately I did not read this review. Obviously there is little to no quality control on this product.

Pros
  • With overload/over-current/overload/under-voltage protection, stable operation.
Cons
  • I vaguely remember
