I loved the build and technology of New Now

As I know that diesel car draws more power than petrol to crank, so I decided to check this on my friends diesel car. I have jump started my friends 2L diesel car for 7 times (1min pause between two consecutive crank) on single charge with 60% battery still left with me. I had disconnected terminals from main battery to ensure that car only draws power from Kit. As well as its charged my Samsung S6 edge+ mobile very fast.

I loved the build and technology of New Now. Always promising quality with very affordable price.

Thank you New Now and team.

This charger works perfectly for car trips or anything else.

This charger works perfectly for car trips or anything else, where one may want to charge 1-2 devices while on the road. Has come in handy often. Charges rather quickly, and let one know when it is complete. Battery level is easily displayed during charging, itself or other devices.


Both my husband and brother-in-law love this little pot!!

Both my husband and brother-in-law love this little pot!! They've been playing around starting everything they can. It works every time. The first thing was a Dodge Ram. Started right up!
