The NOCO Company Reviews 

Bought Noco Boost Plus GB40 in February, 2021 as it says it will start a 2 liter diesel. Used in June and failed miserably. Useless.

Extremely slow; they apparently have a 7-10 day ‘processing’ period (mine was 9 days) and use Pony FedEx with a 1 week transit time.

Bought a noco gb50 Oct 2020. Not used till feb 2021 to try and start a 2l car. Fully charged and it would not turn the engine over. Contacted NoCo for warranty and have been given brexit , non available, warehouse movements as excuses after being told in feb that it had been released under the warranty. Now they will not answer my correspondence
Heard these were the bees knees but no think I’ve got an invalid hive

Bought a GB40 October 2020. Packing and feel of the product is very good, however, I have an issue with it.

I’ve used it several times on varying different size engines. It has started them, but my complaint is it only last a few attempts before runs out of charge and no where near up to 20 as stated.

I emailed their customer service explaining I tried it several times on different size engines but lasts no where near 20 attempts. The reply they sent appears to be templated response clearing not reading my complaint, as they state it depends on size of the engine but their tests often have more than 20 start attempts.

I explained I tried it on varying engine sizes from small to larger and still lasts nowhere near 20!

Still waiting for follow up reply from Noco

I bought a NOCO GB40 for my 2015 Subaru Forester, false peak current, and the battery capacity is the only 24Wh, and still cost me $100. Worked once and has never worked since. Every time I try to start a car, the device just has a click noise internally and fails to start the vehicle. So much for being durable and long lasting...

i have just bought gb70 .The manual is in all different languages. English is in russian .there is no English manual,The on line manual is unreadable.this is very poor start . thinking of returning this back.

Bought a Noco Genius G1100 charger/optimiser which stopped working after less than a year, managed to get a replacement ( which is why I've given 2 stars instead of one) now the replacement has stopped working, appears to be the same issue, response from Noco still hasn't resolved the issue. If I had known the lifetime of this product was only around 12 months, I would have saved some money and bought a cheaper alternative.

Bought a GB150, it was brilliant at first. Very quickly/within two months it dropped from 12v to a 9v output, probably a faulty lithium pack. To this day, can't get it repaired. Such a shame because I really did think it was an awesome bit of kit when it worked. Wish it could be fixed.

Very poor quality and very bad service. Noco does good marketing and the packaging looks really nice... but what it is inside is horrible... we have s work Shop and bought a lot of the Noco stuff. We also use gys and ctek but Noco is the world champion in getting defective... 3-4 of 10 gb150 jumpstarters are defective... really crappy made in China quality and on the level of a 15 euro Charger. Service and communication really poor

bought the NOCO Boost HD GB70

Superb, build quality is good, anyone can use this, it's idiot proof. Well worth the money, no more jump starting car to car. Compact and very easy to charge and use, very pleased.

5 stars for the product and the way they dealt with a warranty claim. NOCO replaced the faulty product, and as the model I had wasn't made anymore, I got a free upgrade :) It was also as hassle free as possible. The G15000 I got is a very good product, too. All in all - glad I chose NOCO!

Just purchased from Auto Zone. Haven’t needed to use it, but now I have it I probably won’t. I can’t comment on previous ratings because I haven’t had trouble requiring contact. I can say, which accounts for the five stars, this is the first company that gives you the option to scan your receipt to the registration..... why hasn’t anyone come up wit this sooner?? I can only think of the thousands of dollars we have lost having to replace items under warranty because I couldn’t find or the receipt got thrown away. Hoping I don’t need to use it, but if I do it’s already with the manufacturer.

Purchased a Genius GB70 Boost/Charger that turned out to be faulty.
Customer service agreed to replace the unit, but almost 2 months later I still haven't received the replacement. Emails only occasionaly responded to telling me that I will receive an update "very soon".

While about a third through a long distance road journey my alternator failed. A garage replacement or full UK recovery was not possible inside a week as the town was to shut down next day for an annual festival and thereafter there were National holidays for a week to a month?

Chosen option was to charge my battery and head for home. Fortunately I had recently fitted an excellent Yuasa 5000 series 80a/h battery. Unfortunately there was no equivalent to ‘Halfords’ to buy a suitable charger from. I eventually found a motorist shop where the ‘best’ they could sell me was a Noco Genius G3500 charger - a 3.5 amp charger.

I was apprehensive because this suggests a charging time of around 23 hours. Basic physics states for a charging time divided the charger output into the battery capacity – e.g. 3.5amps into 80amp/hours = @ 22.86 hours. A 10 amp charger would do it in 8 hours. However, the packaging and the manual both state the G3500 is a ‘2X’ charger, using special technology to charge twice as fast. The manual states 80amps of charge in 11.5 hours.

I needed this as [a] I had to set out early next day to drive in daylight and not have to run lights, and [b] I didn’t want a second day/night in the hotel for £100.

12 hours later my battery was only showing half charged. I waited as long as I could/was allowed in the hotel lobby and even after 4 more hours the battery charge was only nudging 70%.

I should have known; “You canny change the Laws of physics.”
