Review on Mroinge Smart Car Battery Charger And Maintainer - 2A/5A 6V/12V Fully Automatic Trickle Charger And Desulfator For Lead Acid And Lithium Batteries With LCD Display by Tsuyoshi Tendencies

Photo with soda can for scale.Not for instant jump starting, but very worth it to have.My car (Mazda 3) has this defect that if I leave the trunk open, the car runs down the battery because of the trunk electronic lock. It takes about 72 hours to drain the battery. With Covid and driving less, I have had this happen several times. I can jump the car with my other charger or another car, but then since I am not driving it far I have to idle it forever to get more than a surface charge on the battery. This solves that problem.This is not something you hook up to the battery and jump start it right away. It takes at least four to five hours to go from dead as a doornail to being able to start the car at the max setting. So not for an emergency start on the road. Plus, it must be plugged in as well.But if you leave it for a whole day it will get your battery completely recharged.I like that it tells you where your battery charge is at as it goes along.The directions are well written, but in like 6 point font. Have mercy people!I do wish it came with a pouch for storage, but at this price it is fair it is not included.It does get warm when used at 5A.
