- Reviewed in Canada on April 17, 2021This is the fastest most competent smart charger I鈥檝e ever used. At 50-Amp it will completely charge a depleted 100 amp-hour battery in less than 2 hours. In most instances, it鈥檒l likely top up any 6v, 12v, or 24v battery you have in less than an hour. Full featured, with additional modes like desulfination and force charging, this charger does it all and quickly. All around impressive, including the packaging, case and heavy duty nylon braided silicone cables and clamps. However, it鈥檚 not sealed or weatherproof. There are vents inside the side handles, and quiet cooling fan(s) can be heard running when it鈥檚 in use so I would be cautious using it outside or in incremental weather. For a 鈥榬elatively鈥 compact 50Amp smart charger, I鈥檓 not surprised that it uses active cooling. The fact that it鈥檚 not sealed or weatherproof is a little disappointing, and I would have preferred a hard blow molded case over the included EVA case.
Overall, I鈥檓 very impressed with this Narco charger, and they have been my go to for years because of their features, reliability and compact size. I own several, and this is now my new main garage bench charger. You can find faster cheaper 100 - 150 amp chargers, but they鈥檙e not multistage, multicemistry compatible, 鈥渟mart鈥 or as feature rich. Well worth the features and time savings, but individual needs will dictate whether it's worth the price of admission.
As for features, it is capable of charging 6v, 12v, and 24v, including different multicemistry batteries including Lithium. It also has temperature compensation, reverse polarity protection, power supply mode, repair/desulfator high voltage pulse mode, trickle/maintenance, force manual mode and 10 amp charging mode for smaller batteries. The force charge mode overcomes one of the limitations of many smart chargers, which won鈥檛 actually start charging unless they鈥檙e detecting sufficient voltage, which sometimes isn鈥檛 present on badly neglected batteries. The desulfator/repair mode also helps recondition batteries that wont accept or hold a charge, and does make a difference. It will not restore batteries to 100% but it can restore them enough for them to accept a charge, so you can get some more life out of them.
It also has automatic temperature compensation charging, which allows the charger to automatically adjust the charge voltage for optimum charge efficiency depending on the ambient temperature. This is an often overlooked 鈥榮mart鈥 feature but critical for optimal battery charging. It allows it to maintain a more accurate end voltage threshold balance between a full charge vs over-saturation. It does this by automatically lowering the voltage threshold when charging in warmer temperatures, and increasing it slightly in cooler temperatures. This minimizes sulfation on the negative plates, and grid corrosion on the positive plates which can damage the battery over time and lead to off gassing and water-loss.
Despite its extensive features, it鈥檚 easy to operate. One button is used to cycle through the modes/battery types. Hold for 3 seconds for repair mode. Hold for 7 seconds to force charging - once all the modes start flashing, use the mode button to cycle to the correct battery type and it鈥檒l start force charging. The display provides clear information regarding the charge status and is easy to understand and intuitive.
Final thought: Yes, you can find a faster charger, but you鈥檇 be hard pressed to find a better more competent fast smart charger. However, it鈥檚 not weather sealed so outdoor use/installation may be limited.
