Do not buy the NOCO GB40 if you have a hybrid. It's underpowered and requires a full charge plus the boost to have a chance to scrape the advertised power and a lot of times it won't even work to jump start your car. NOCO claims it will work "up to twenty times" but in reality you're lucky if you get ten. For me it worked twice.
Cons: underpowered, doesn't work well
Vehicle:
Toyota
Part number: GB40
I have a NOCO GB40 in my boot, used it 4 times now from starting my own 1.6 diesel all way way to a big VW amarok so I've been happy with it so far
Pros: reliable, starts various diesels
Part number: GB40
I think I'll stick with my Noco Genius which is quite light and smaller than a brick, at $99. I have one in all my vehicles. Works great.
Pros: works great, light and small
After seeing some of the dead battery posts here I decided to get a booster to keep in my ‘23 Kicks full-time and settled on the Noco GB40. It’s a lithium battery so it’s very small and easy to stash. Haven’t had to use it on my own car but jump started my neighbour’s V6 Pathfinder just fine. It also has USB so you can charge your devices if you’re stuck somewhere.
Pros: small, easy to stash
Cons: probably not cheapest
Vehicle:
Nissan
I have the 1,000 noco jump starter and it fired up my 7.3 up immediately in 36° weather the other morning when I accidentally left the dome light on all night. Definitely a good choice
Pros: fired up immediately, good choice
We have two Noco GB70's. The 50 or even 40 should work fine. These are well regarded units.
Pros: well regarded units
I work at Mazda and I try the Nocos and there okay for a here-and-there and I notice the cheaper ones die quicker.
Pros: okay for a here-and-there
Cons: cheaper ones die quicker

I have a Noco Boost X GBX45. The amperage on that is 1250 A, as long as you have higher than the CCA rating of the battery, you should be good.
Pros: higher than CCA rating
Vehicle:
Mazda
I have a noco boost gb40, had oem battery that was completely dead, no lights had to use key to unlock door. Hooked it the jumper, wait about 10 seconds as battery was really drained, and CX started right up.
Pros: CX started right up

Mazda
