Buying guide: the best jump starter for zero turn mower
Peak power and engine coverage
Peak power runs from 500A on the NOCO GB20 to 10000A on the OXILAM pack, with the GP4000 at 4000A, the GP3000 at 3000A and the YESPER at 1500A. Engine coverage follows a similar spread: the OXILAM listing states all gas and diesel engines, the GP4000 states all gas engines and diesel engines up to 10.0L, the GP3000 states 9.0L gas and 7.0L diesel, the YESPER states up to 7.0L gas and 5.5L diesel, and the GB20 states up to 4.0L gas with no diesel coverage stated. Match the engine to the stated coverage. See the best battery for zero-turn mowers.
Capacity and starts per charge
Capacity is stated on two packs: 24000mAh on the OXILAM and 16000mAh on the GP3000. Starts per charge is stated on two packs as well: up to 20 on the GB20 and over 60 times on a full charge on the GP4000. A pack that states neither figure has to be judged on peak power and coverage.
Protections and certifications
Three listings state 10 protections: the OXILAM with UL, FCC and CE certifications, the GP4000 with SUPERSAFE technology and metal clamps, and the GP3000 with spark-proof clamps and reverse-polarity alerts. The YESPER also states 10 protections. The GB20 states patented spark-proof and reverse polarity protection with an IP65-rated housing.
Weight and what is in the box
Stated weights run from 0.6834330122 lb on the YESPER spec table to 3.94 lb on the GP4000 spec table, with the GP3000 at 1.39 lb, the GB20 at 2.4 lb and the OXILAM at 3.15 lb. The GP4000 listing states the wall charger is not included.
Keeping the pack ready
The OXILAM listing advises charging every 3 months after long idle periods and keeping charge greater than 50% before starting. The GP4000 listing advises charging every 2-3 months after idle periods. The GP3000 listing states auto-sleep tech that keeps charge for 18 months with a recharge every 90 days. The GB20 recharges in 3 hours; the YESPER listing states no recharge interval.
Read the manual, keep children and pets out of the yard while you work, wear eye and hearing protection and sturdy footwear, and never exceed the slope rating of your machine. Refuel only with the engine off and cool. See CPSC lawn mower safety. Read our Safety Disclaimer.
Matching It to Your Property
- Keep the pack in a glove box or emergency kit, as the NOCO and OXILAM listings describe.
- For shed or truck-box storage, the GB20 lists IP65-rated housing and the GP4000 lists hardened plastic with rubber corners.
- Use the power bank for phones and devices, since every listing here states device charging.
- Use the LED flashlight for low-light work, since every listing states strobe or SOS modes.
- For cold-weather starts, the GP4000 and GP3000 listings state operation from -4°F to 140°F.
