CarCareTruth's Analysis
Last reviewed May 26, 2026
TL;DR No third-party certification found (no UL or ETL listing confirmed). The labeled peak-amp claim has not been independently verified. Community reception is broadly positive for passenger cars and light trucks; cold-weather starting confirmed in sub-zero conditions. Standard Li-ion battery; no active CPSC recall as of 2026-05-25.
What it is and how it performs
The A58 is a 12V lithium-ion jump starter claimed to start all gas engines and diesel up to 10L, with a label claim of 4000A peak — a figure that has not been independently bench-tested. No UL or ETL listing was found in third-party certification databases, and CE marking is not confirmed in the product listing. The battery chemistry is standard Li-ion; at least one verified reviewer reported holding a charge for 6+ months of trunk storage with no top-off.
Community performance is broadly positive for sedans, SUVs, and light trucks, including cold-weather starts. One professional who jumps 15–20 vehicles per day flagged a 15-second boost limit and noticeably thinner cables compared to premium competitors — the cables and connector are the documented weak point; a 3rd-party connector upgrade resolved reliability issues for that reviewer. AVAPOW's warranty replacement process is consistently praised across multiple reviews.
Who should buy — and who should skip it
Good fit for casual drivers who want affordable trunk emergency insurance for a passenger car or light truck and will tolerate the occasional charge check. At under $100 with 3,500+ ratings at 4.5 stars, the value is clear. Skip it if you start large diesel engines, need confirmed UL/ETL certification, or require sustained high-output performance under professional conditions.
Safety and environmental impact
No UL or ETL certification was confirmed; no CE marking verification found in the listing. Standard Li-ion battery chemistry — no documented thermal-runaway incidents in the CPSC database or community reviews as of 2026-05-25. No active CPSC recall. Li-ion batteries are recyclable via Call2Recycle drop-off; no AVAPOW manufacturer take-back program was found.
Frequently asked questions
Does the AVAPOW A58 really deliver 4000A?▾
The 4000A figure is a label claim. No independent bench measurement (Project Farm or equivalent) was found for the A58 at time of this review. Community reviews confirm the unit starts passenger cars, SUVs, and light trucks under normal and cold conditions. One professional user who jumps 15–20 vehicles per day noted the unit 'does not put out 1/2 the power or for the length of time' compared to a NOCO Pro X, and identified the cables as visibly thinner.
Is the AVAPOW 4000A Jump Starter UL-listed?▾
No UL or ETL listing was found for the AVAPOW A58 in the UL Product iQ database (productiq.ul.com) as of 2026-05-25. The Amazon listing and product spec table do not claim UL certification. CE marking status was also not confirmed in the listing. Buyers who require a third-party lab-certified unit should consider UL-listed alternatives.
How long does the A58 hold a charge in storage?▾
The manufacturer claims up to 12 months of standby. At least one verified purchaser reported the unit held a usable charge after more than 6 months of trunk storage without a top-off. Standard Li-ion chemistry — charge will degrade over time; for emergency use, check the indicator before relying on it after extended storage.
Are the cables on the AVAPOW A58 adequate?▾
For passenger cars and light trucks, community reports are broadly positive. However, one professional reviewer who jumps 15–20 vehicles per day described the cables as visibly thinner than premium alternatives, with a 15-second boost limit. After the stock cable/connector failed, a 3rd-party connector upgrade restored reliable performance. For occasional personal use, the stock cables are generally sufficient.

Awesome little jump starter!
I have an old Generac generator that we use when we have power failures or other things happen and try to remember to start it every month or two to keep the gas clean and make sure everything is going well. The last few times, it is really slow to start and pulling the thing to start is a nightmare since it is so big! Instead of replacing the battery pack, I decided to spring for this for just a little more. The generator has the connections to jump start right near the push button, so it is a breeze to hook up and it cranks way better than the battery pack that I bought a couple of years ago ever did!I am looking forward to having this to be able to jump all of my devices that have starters as well as for backup power in case we need it. It seems to have great safety features, after cranking for a while (since I turned the choke the wrong way) it shut off the start ability for just a second. I let off the button on the generator and the pack reset itself and was ready to crank again in about a second and a half.I love that it has a case that is big enough to keep all the parts in, I have a habit of collecting random cords in boxes, so my life is miserable when I need to find stuff sometimes.I hope it holds up to use and storage, just remember to charge it as soon as you get it, it showed four out of four bars, but when I plugged it it, it charged for a couple of hours while blinking the last light.I hesitated to buy this, thinking I wasn't sure of the technology or if it would have the power of a regular generator battery but it has won me over in a big way!Edit: I was using it to charge something a few weeks ago and it completely locked up. I let it sit for a few hours and it still didn't work on either the USB ports or the battery terminals. The terminals would start but would click and act like there was a short circuit within a few seconds, only allowing use for a very short time. I contacted the seller, they got right back to me, but I had left for a trip. When I got back home, I tried it and it worked perfectly. Apparently, it needed a bit more time to reset! I appreciate the quick response from the seller and I have now used it to charge a camera, a phone (multiple times) and jumpstart a truck without any hiccups at all. I still think it is a great product - just the right size and weight to be in my truck all the time. I don't have any hesitation recommending this for anyone since I know the seller backs it up with fast support response and stands behind their products.
