NOCO vs GOOLOO: is NOCO worth the extra money?

The most common praise and complaints from owner reviews on Amazon, retailer sites, forums and Reddit. Sources are listed at the end.

NOCO Boost Plus GB40

• Owners say it starts cars and small trucks right away, and several have jumped dozens of vehicles with it.^*38–40
• Many say it holds its charge for a long time between uses.^{*38, 41}
• It can struggle with a V8 or a battery that is fully drained. A Ram forum owner says "It struggles to turn over a V8."^{*38, 42}
• Some Amazon reviewers say their unit stopped recharging or died within a year.^*38

GOOLOO A3

• Owners like that the pump fills tires fast and that one box handles a dead battery and a low tire.^*43, 44
• The most common complaint: some units stop working after a couple of months, or won't charge again.^*43–45

GOOLOO GP4000

• Owners say it is easy to use and holds a charge for months in the car.^*46, 47
• Some say it stopped holding a charge or died after a few uses.^*46
• One RV forum owner's first try failed on a battery that had dropped below 7.5 volts. The manual is online only, which one Walmart buyer disliked.^*47, 48

"It's cheaper." True. The A3 costs $29.99 less than the GB40, and the GP4000 costs $60.00 less than the GB70. If price comes first, get the GOOLOO.^*5

"It has a bigger battery." True. GOOLOO's manuals list 44.4 Wh for the A3, against 24 Wh on NOCO's spec page for the GB40.^{*10, 20} A bigger battery holds more charge. It doesn't tell you how well a pack starts an engine.

"It's rated for bigger engines." GOOLOO rates the A3 for 9 L gas; NOCO rates the GB40 for 6 L.^*1, 2 The two makers rate their packs differently, and we found no standard test for these ratings, so the numbers can't be compared one to one. Both cover a 4-cylinder or V6.

"The warranty is longer." True: 18 months against 12, or up to 30 if you register and take the newsletter.^{*6, 7, 16}

"It works in the cold." On paper, GOOLOO's range is wider. You can charge it down to 14°F; NOCO says to charge only above 32°F. Both list -4°F as the coldest they run.^{*12, 21–23}

"The A3 has a tire pump." True. If you want one box for a dead battery and a low tire, see our air compressor pick; the A3 is it.

The same trade-off holds one size up. The GP4000 ($79.99) costs $60.00 less than the GB70 ($139.99) and has a bigger battery: 74 Wh in GOOLOO's manual, against 56 Wh on NOCO's spec page.^{*5, 9, 24} GOOLOO rates it for diesels up to 10 L; NOCO rates the GB70 for 6 L.^{*11, 25}

For a V8 gas truck, the GB70 is our pick. For a 6.6 or 6.7 L diesel pickup, neither is ours: NOCO rates the GB70 below those engines, and we pick a pack whose maker publishes two-battery steps. See our diesel truck pick.

Starting a completely dead battery. NOCO packs have a manual override: hold the button for 3 seconds to start a battery below 2 volts. NOCO warns that it turns off all safety features, and misuse voids the warranty.^{*13, 22} GOOLOO puts a BOOST button on the clamp cable that forces a start on a very low battery. Its manuals say to connect the clamps correctly first, and not to reverse them after pressing it.^{*19, 31, 32}

Safety wording. NOCO calls its clamps spark-proof, with reverse polarity protection.^*1 GOOLOO lists "10 key protections," including reverse connection protection, and a solid red light if the clamps are backward. Its manuals don't use the word spark-proof.^{*19, 33, 34}

GOOLOO's listings disagree on upkeep. The GP4000's Amazon listing says to charge it every 2-3 months, and the GT4000S listing says regular charging "is not necessary." GOOLOO's manuals say every 3 months, so we use that.^{*8, 11, 35}

Where they're sold. On Amazon, the NOCO packs are sold by Amazon.com and the GOOLOO packs by GOOLOO.^*5 GOOLOO also lists its own store, Walmart, eBay and AliExpress.^*16 NOCO sells on its own site, and Ford.com sells the GB70 for $295.00.^*36, 37
