The MCP1640-I/MC is a 0.65V start-up synchronous Boost Regulator with true output disconnect or input/output bypass option. The MCP1640 is a compact high-efficiency fixed frequency synchronous step-up DC-DC converter provides an easy-to-use power supply solution for applications powered by either one-cell, two-cell or three-cell alkaline, NiCd, NiMH, one-cell Li-ion or Li-polymer batteries. It provides very high efficiency through integration of the low resistance N-channel boost switch and synchronous P-channel switch. Low-voltage technology allows the regulator to start-up without high inrush current or output voltage overshoot from a low 0.65V input. High efficiency is accomplished by integrating the low resistance N-channel boost switch and synchronous P-channel switch. All compensation and protection circuitry is integrated to minimize the number of external components.

Refreshing orange scent
These are effective at refreshing your disposal. When I am done cleaning up my kitchen I put 2 drops in the disposal side of my sink and briefly pulse the disposal to break open the drop. Don't run any water as this will wash away the drop and the fresh orange scent. I am very sensitive to perfume or floral fragrances - these are just the right amount of orange scent to make your drain smell fresh without the scent overwhelming the kitchen.

Easy to use and work great
These are great. Helps with odors and grease cutting. So easy to just drop a couple in after use.

They smell AMAZING!!
Amazing quality, they smell great, and they last quite awhile! I like switching between the orange and lemon scents, as it’s nice to switch it up! A great price for the quantity and quality!

Easy To Use
Easy to use product with nice scent. The scent is a bit lighter than I thought it would be, but I suppose you could use a couple at a time. Compared to other brands I thought a good value as you get more. Seemed to work well. Popped one in, ran the disposal and the smell seemed to be gone.
