There is no single consensus winner among the recent tests: Car and Driver named the Clore Automotive Jump-N-Carry JNC325 its Best Overall in May 2026, while Road & Track chose the Battery Tender Jump N Start 2000 AMP as its Top Pick in September. For a compact option, Car and Driver picked the NOCO Boost Plus GB40. These are separate outlet rankings based on different tests, not a standardized head-to-head comparison.
2026 tested picks at a glance
| Model | What the review selected it for | Useful context |
|---|---|---|
| Clore Automotive Jump-N-Carry JNC325 | Best Overall — Car and Driver, May 2026 | The review reported 24-inch cables and said the unit started its test vehicle with ease after the tester used the override button. Read the Car and Driver test. |
| NOCO Boost Plus GB40 | Most Compact — Car and Driver, May 2026 | NOCO’s December 2024 data sheet specifies support for 12-volt batteries and gas engines up to 6.0 liters or diesel engines up to 3.0 liters. See NOCO’s GB40 data sheet. |
| Battery Tender Jump N Start 2000 AMP | Top Pick — Road & Track, September 2026 | The outlet tested on a dormant FJ80 Land Cruiser with a long-dead, comparatively young battery. Read the Road & Track test. |
Road & Track also named the NOCO BoostX GBX155 Most Powerful and the CTEK CS Free Most Versatile in its September 2026 comparison. Its results should not be treated as a replication of Car and Driver’s test.
How to choose a jump starter for your vehicle
Check the vehicle’s system and engine
Start with the vehicle manual and the jump starter’s instructions. Confirm that the unit is intended for your vehicle’s battery voltage and engine type and size. For example, NOCO rates the GB40 for 12-volt batteries, gas engines up to 6.0 liters, and diesel engines up to 3.0 liters. That is a model-specific manufacturer claim, not a general rule for jump starters.
Car and Driver cites 400–500 CCA as a typical passenger-vehicle figure in its May 2026 buying guidance, but that is not a universal requirement or standard. Check your battery’s actual rating and the starter maker’s compatibility guidance rather than choosing by a broad typical figure.

Do not compare peak amps alone
Peak current is not the same as sustained cranking output. Car and Driver distinguishes the two and notes that lithium jump starters typically provide high output briefly. Road & Track says lithium units may deliver high current for roughly two to five seconds before power cutoff; this is category guidance, not a specification that applies identically to every model. Use the vehicle’s requirements and each product’s instructions to judge suitability.
Account for handling, storage, and recharging
Portability matters if the unit must live in a vehicle, but so do cable reach and clamp usability. In its May 2026 test, Car and Driver reported that the GB40 was small, but its leads were short and its clamps difficult to squeeze. It also observed that after a test jump on a severely drained battery, the GB40’s charge indication fell from full to 25 percent. That was one review’s test outcome, not a promise about how many starts any owner will get.
Rank #2

The same review lists the GB40 at 30 watt-hours, while NOCO’s December 5, 2024 data sheet specifies 24 watt-hours. The official manufacturer specification is 24 Wh; the review’s different figure is a published discrepancy, not a reason to silently substitute one number for the other.
What the tests actually establish
Car and Driver: JNC325 and GB40
Car and Driver says it tested units on vehicles with depleted batteries and assessed weight, ease of use, cable length, clamp quality, portability, stability under the hood for power stations, and additional features. In its test, the JNC325 required use of its override button and then started the vehicle with ease. The GB40 started a car after override activation; the review also recorded the charge-indicator drop after its severely drained-battery test. These are observations from that outlet’s test conditions, not guaranteed performance on other vehicles.

Road & Track: Battery Tender and other picks
Road & Track says tester Justin Helton evaluated jump starters on a dormant FJ80 Land Cruiser with a long-dead, comparatively young battery. The test considered charging times, safety features, ports, lights, and ease of use. Its September 2026 designations were Battery Tender Jump N Start 2000 AMP as Top Pick, NOCO BoostX GBX155 as Most Powerful, and CTEK CS Free as Most Versatile. Because the outlets used different vehicles and methods, their picks answer different test questions rather than forming one shared ranking.

NOCO warns against attempting to jump-start a damaged or frozen battery and flags electrical shock, explosion, and fire hazards. Built-in protections do not replace careful setup: read the GB40 instructions and the vehicle manual, verify compatibility, and do not proceed if the battery is damaged or frozen.
For a hybrid or electric vehicle, Road & Track says a portable jump starter may be used only for the 12-volt auxiliary battery, not the high-voltage traction battery. Follow the vehicle manual for the correct procedure.

After a jump: recharge the right battery
A jump starter supplies a starting jolt; it is not a substitute for charging a depleted vehicle battery. Car and Driver says jump starters do not significantly recharge the vehicle battery and reports Optima Batteries’ advice to connect a charger as soon as possible after a jump. If the battery repeatedly goes flat, a jump alone does not resolve the underlying issue.
Keep the portable unit charged according to its own manufacturer’s instructions. Car and Driver recommends recharging stored units about every six months, while Road & Track advises doing so every few months, especially before winter or a long trip. Those are outlet recommendations; the unit’s current manual takes precedence. Road & Track also advises keeping jumper cables as a backup.
