Worked great for my app

Boosts vehicle voltage to charge the LiFePo battery via the WMR Epic PWRgate (which must have an onboard voltage booster).

Pros
  • Everything great!
Cons
  • Repair

Suitable for power accessories

The discrete wire modular system worked well for my application. Works as advertised but regulates with a lower input voltage, maybe around 6V or so. About 90% efficient at 200mA output where I use it.

Pros
  • Easy assembly
Cons
  • There are other interesting options.

Solid - works well with power accessories

Good product, I put this on a very dead battery and it drew 26A at 11V and converted it to 15V at 12A or so. Runs perfectly and is very happy with its performance. .The cable (1.5mm) to the device was too hot to touch (I temporarily plugged in the cable) but the device didn't get warm - the cables are good and thick, which come with the device. During operation, a very weak high-frequency noise is emitted - hardly noticeable.

Pros
  • Confident
Cons
  • Not trendy

Performance boost for 12 volt driving!

I connected this boost converter to my kid's 12v truck (brand PW) to give a little speed boost. If I connect it before the footswitch, I increase the high-speed output from 12V to 15V and the low-speed output from 6V to 7.5V. That 25 percent increase in performance results in a small but noticeable increase Speed boost safe for kids and kids can't just burn engines. It also regulates the power so that when the battery is low and the voltage drops below 11V, the high-speed output is still 15V…

Pros
  • Best in its niche
Cons
  • I'll add later
