🗣️ Jennifer C
I ended up running my battery down shortly after buying this NOCO and quickly got to test it out extensively. It worked very quickly and I was able to get my car moving many times before needing to recharge it. Also used it to resuscitate a “bricked” Nissan Leaf with the manual override button. My only complaint is the plastic tips on the clamps chipped after many uses, but otherwise a great product.
