Out of the box, the NOCO GENIUS5, 5-Amp fully-automatic smart charger is very well packed. The unit is so tiny none would think it is actually very powerful.

If you are looking for a fantastic all-in-one charger, that can function as battery desulfator, maintainer, trickle charger, and battery charger for your cars (including the classic ones), boats, trucks, ATVs, motorcycles, lawnmowers, and so forth, look no other.

This charger is in fact the upgrade model of the NOCO Genius G3500. But you will be getting 65% more power in a 34% more compact size. To put it briefly, it is a nice upgrade. And, if you owned a NOCO charger previously, this charger will work with the battery connectors from your previous charger.

Let’s go to the appearance and what it can do.

NOCO GENIUS5 Compact Design

Weighing only 1.59 pounds, this charger is very small and lightweight. It is a very well built product, too.

What is in the box?

The NOCO GENIUS5 comes with the user guide and warranty card, the battery clamps with integrated eyelets, mounting bracket and straps, 2x screws for the included bracket, and the charger itself. The screws are actually self-tapping screws.

Battery Clamps

Furthermore, the battery clamps are excellent and easy to use. Most important, they are secure while you are charging your battery. The AC/DC cables are approximately 6 ft or more.

For the connectors, the NOCO GENIUS5 comes with rings terminals that help to connect the cables to its clamps, secured by the two included two screws. If you remove these screws (as they are removable) you will get ring connectors.

One thing though, that this charger does not have SAE standard connectors, but thankfully they (NOCO) sells a cheap converter like this one below.

To access the eyelets that are integrated with the clamps, just remove the clamps, then you can also use it as a permanent battery connection.
