The NOCO Company Reviews 107

Battery low

Bought a Toyota Yaris Cross in January 2025 and read about the underpowered 12 Volt Battery problems. Then purchased the Noco Boost Plus GB40 as insurance for those "just in case" moments.

Our next door neighbour also has a Yaris Cross and her bettery was flat yesterday. Tried the GB40 and it worked. Got the car going first time. Hopefully I'll never need it but it's there - just in case.

Really bad experience with Noco customer support. I bought 2 Noco Genius 1's because I have 2 cars in my garage. 1 worked and the other stopped working in a short period of time. Noco support emailed a troubleshooting guide, which I executed. Still the defective unit just flashed and did not maintain a charge. I asked if I could send it back and just kept getting degrading emails from Noco support like checking fuses, which was already on the troubleshooting guide. Noco does not stand behind their product.

Bought NOCO GBX 155 just little over 2 years, jump started 8 times, recharged 8 times.

Now my jump starter cannot recharge anymore.

Contacted NOCO, they won't even bother to respond becuase it is out of warranty.

What a COMPANY!!!
No wonder they name themselves NO CO...

NO MEANS NO

AVOID NO CO AT ALL COST

NO CAUSE

DO NOT PURCHASE
Late September 2024 I purchased a NOCO GENIUS2 charger/maintainer.
Upon arrival and testing, it failed repeatedly to automatically switch from all lights-on (charging) to only green-on (Maintenance), after the battery was fully charged, which means it was overcharging and damaging the battery, even possibly a safety hazard. Called NOCO and talked to 2 technicians, one resisted the evidence, the other one agreed to check the unit, but indicated that if it was OK, they would send it back (which seemed reasonable). They authorized the return (at my cost), would test the unit for three weeks and get back to me. Which they did, and indicated 2 diodes were no good, and sent me a new different serial number unit. It took a week to arrive, I tested it for about a week, and it consistently did the same malfunction, would not switch automatically to Maintenance after a full charge was reached. Long story short, the same thing happened a third time!
Given the ordeal, I contacted NOCO and requested a full refund, and they simply said NO, that they would only authorize sending a fourth new unit. To which I said, there is just no way that I am going to lose more of my time testing NOCO's inventory until I came upon a functioning unit. They should have tested and retested the second unit before shipping to me, but simply did not. So, it speaks very poorly of NOCO's quality control measures, and of their dismal customer service.
I decided to call Amazon and let them know what had transpired with NOCO, knowing that over four months had elapsed since the first unit arrived, but the person I talked to understood that NOCO’s attitude was not proper and authorized the full refund. So…. good job Amazon, and STAY AWAY from NOCO products. Save your money and the aggravation of having to deal with a company that is not interested in assuming responsibility for malfunctioning products they produced. As expected, "all things go well when there is no problem", but if there is an issue with a product, which is when the company should stand behind the brand, it does not happen. Simply put, DO NOT purchase products from NOCO. Three malfunctioning units in a row, is more than enough evidence of the poor quality of their products, of lack of adequate functional quality control, not to mention dismal customer support, most likely all three.

Moreover, if a company possibly has a different arrangement with Amazon about its warranty, returns and refunds (which NOCO was not willing to accept, only implied it), it should clearly say so in the Amazon description (and NOCO should verify it’s there) including implications to the customer, so he or she is aware before making the purchase decision; otherwise, this is flagrant false advertisement by NOCO.

Something that help me considerably to determine the malfunctions was: I used a digital voltmeter to determine battery voltage while charging and when it was fully charged; plus I was fortunate enough to have and test against another equivalent charging amperage charger of another brand, and it consistently switched from charging to maintenance when the battery reached a full charge.

Bought a GB70 on amazon, arrived dead, charged it and left it ready to use, 1 month later I needed it and it was dead, charged again, same thing dead a few weeks later. Out of 30 day return window and 3 ignored emails to their online support. AVOID!

Purchased Noco Genius 5 from Halfords in Loudwater. Advised by Halfords employee. Unwrapped product. No instructions inside, no bag to keep product in and website help not operative. Most expensive battery charger ever purchased £83, and most useless as cannot find out what Modes should be selected. Don't want to ruin my vehicle battery etc. Not impressed.

Bought a Noco gb40 boost plus in January 2024. It has probably been used twice per month since and now its not holding charge/charging properly.In truth a total waste of money for all the use its had.

The worst investment in tools ever. The gb40 was purchased in Belding Michigan at a parts plus auto parts. Product was worthless.. wouldn’t jump start anything bigger than a lawn mower. The solution was to pay the shipping to send it back to the manufacturer and wait for them to decide if it was out of specs. I will be filing a complaint with the better business as well. I have been a certified mechanic for over 30 years and by far my worst investment

SAFETY WARNING - fried fuses on my BMW M5

I purchased a NOCO charger with OBD charge cable.
Within a few seconds of connecting this to my BMW M5 F10, it blew the fuses including ECU. The windscreens wipers came on and wouldn't turn off, and nothing else worked. I had to remove and check 200 fuses, incl the ECU fuse which is one of the ones that had been fried. If the fuse hadn't done it's job quickly, this could have fried the ECU too, costing thousands to replace. I tried to contact NOCO for support through various channels but was ignored

It is supposed to be a safe charger, but it caused me a few hours of panic while I traced all the blown fuses, and was close to calling the dealer to get it transported for repair

Bought their GB50 jump starter and box has no charge lead. Hoping they reply as Halfords been unhelpful, can’t even use it now!

scam company. doesn't charge my 12v car battery straight out the box, even if the battery is 12.7v. it just clicks over and over. "manual override" is a joke, and does not work either.

Noco Genius 1 died 10 months from new. Contacted customer services for a warrenty claim. Was asked:
1) for proof of purchase and S/N - provided.
2) video of fault and picture of S/N on product - provided.
3) a photo of me having cut the cables along side product with S/N - told them to shove it.
Endless hoops to jump through! Why they need me to cut some worthless cables idk.
Warrenty is defacto worthless. Buy something else.

your company must have some real geniuses working for it if it takes a 65 watt charger to charge it why does it not come with one .Am i supposed to use the vehicle with the dead battery to charge your product DUH DUH DUH DUH . i spent 400$ on designed stupidity. SAVE YOUR MONEY AND REDUCE YOUR FRUSTRATION BY NOT BUYING THIS PRODUCT

Just would like to say what a wonderful support team. Answered every email and replaced my battery charger. Very please with their support, where others don't even respond or help you.

STAY WELL CARE OF THESE PRODUCTS THEY HAVE KNOWN MANUFACTURING ISSUES SUCH HAS THE ON/OFF BUTTON & THE RECHARGING OF THE BATTERY THAT NOCO EXPECT YOU PAY AGAIN TO REPAIR I USED A £80 CHARGER ONCE BEFORE ITS STOPPED WORKING AND WOULDNT TURN ON , POOR QUALITY UNINTRESTED MANUFACTURER , UK STOCKESTS SHOULD STOP STOCKING THESE PRODUCTS LIKE THE GB20 GENIUS SPORT THEIRS NOTHING GENIUS ABOUT EITHER THIS PRODUCT OR THIS COMPANY HALFORDS STOP STOCKING THESE PRODUCTS. PRODUCT A COMPLETE WASTE OF MONEY.

I could t give less than 1 star
I used my Noco gb 70 4or 5 times only and the power button stoped working , it started with the flush light that stopped suddenly and end up with no more power even with full charged battery
Customer services said it’s out of warranty and the serial number is an old model and cannot do anything
No more Noco and an advise ,stay away

Terrible product barely used in a garage environment and didn’t hold up to any tests. Sad and disappointing from the very beginning to be honest.

1 OR 0 IS FOR THE PROCESS I GAVE A two because the end result my battery was warrantied.
I started a return claim about April 1st 2024. A few emails went back and fourth most responses from NOCO where several days later. I eventually got frustrated when PAT did not return emails. Almost 30 days later i was informed NOCO would warrenty the battery and i would receieve a confirmation email. I waited a few more days for confirmation. I was forced again to call NOCO.
After a few frustrating calls a month of waiting I was informed they would ship me a battery. I live off the road and found it's better to add shipping notes to any shipment I receive and I receive several a month without issue. This allows the couriers to know exactly where I am. So I again called nocco to add shipping notes. When talking to them this time I found they had a wrong street number attached. I corrected that and asked to add the shipping notes. Confirmed all was correct and moved on.
Today MAY 2ND I get a call from FedEx today stating they needed a proper address. I asked fedex what address NOCO provided not only did not take my explicite shipping notes they had the wrong address that i corrected with them days earlier .So when I receive the battery tomorrow it will be over a month of trying to warranty a battery that could be done in 15 minutes in any store. TERRIBLE SERVICE.

Blackview BV9300 pro is a brick..Weighs in at over 500 grams, The difference between this an a pound of butter is the phone doesn't melt. Side buttons are always in the way, NFC, control is smack dab in the middle of the unit so you cannot put a mag plate there, not that that matters as it would fall off due to the weight. The weight comes from the battery, obviously, 15k + has to weigh at least 512g.
But is the battery size worth it? As I write it has used 13% of the fully charged battery in 11 hours, and will take equally as long to charge up again. I don't think I could give this away in good conscience ☹️.
I am only here because I couldn't find a review input on Noco Site, Great delivery, great transfer of cash, lousy product.
