This guide draws on NOCO’s GB40 data sheet and user guide, Fanttik’s product page and manual, AstroAI’s CZK-3674 manual and AAA’s kit list. Read how we research.
Jumper cables or a jump pack?
AAA’s emergency kit list accepts either one, listing “jumper cables/jump pack.” Jumper cables need a second running car, so they only help when another driver can pull up next to you.
A jump pack works on its own, with no second car. The catch is upkeep: it carries its own battery, so it has to be kept charged to be any use. Cables need nothing between uses.
Our rule: choose cables if a second car is usually nearby. Choose a pack if you often drive alone, since that’s when there’s no second car to help.
The three picks side by side
One pick jumps the battery and two top up tires.

| Rated output | 1000A peak | 150 PSI (10.3 bar) | 100 PSI (6.9 bar) |
| Weight | 1.65 lb (0.7 kg) unit, 2.4 lb (1.1 kg) with clamps | 1.74 lb (0.8 kg) | Not listed |
| Light | 100 lumens, 7 modes | 40 lumens | LED, no lumen rating |

Specs come from NOCO’s GB40 data sheet, Fanttik’s product page and manual, and AstroAI’s CZK-3674 manual. “Not listed” means the figure isn’t in the CZK-3674 manual.
NOCO GB40: the jump pack
For drivers who are often alone, the GB40 is the pick, because it starts a car with no second vehicle.
NOCO Boost Plus GB40
A compact 12V lithium jump starter. NOCO rates it at 1000A peak, for gas engines up to 6.0L (366 cu in) and diesel engines up to 3.0L.
Key specs

- Gas engines up to 6.0L, diesel up to 3.0L

View on Amazon (opens in a new tab)NOCO rates it for 12V lead-acid batteries only, including AGM and EFB types. Its 1000A figure is a peak rating, the highest burst of current a maker claims; see what peak amps mean.
The user guide says the GB40 ships partially charged, so charge it fully first. It also discharges over time when unused, so recharge it before you need it. Its USB port can recharge a phone up to 4 times, per NOCO’s data sheet.
If the car doesn’t start, NOCO’s guide allows no more than 5 attempts in 15 minutes before a rest, as explained in how to use a jump starter safely. For a bigger engine, compare sizes in NOCO GB40 vs GB70.
Tire gear: gauge first, then cordless or plug-in
Start with a simple gauge, the cheap way to check whether a tire is low. An inflator then tops up a low tire so you can reach a shop, but it won’t fix a puncture. A spare covers a flat, so the two do different jobs.
For drivers who want no cord and no engine running, the Fanttik X8 Apex is the cordless pick.
Fanttik X8 Apex
A cordless, rechargeable tire inflator with a digital display and preset modes.
Key specs
- Up to 150 PSI (10.3 bar)
- Cordless, about 40 min per charge
- 1.74 lb (0.8 kg)

View on Amazon (opens in a new tab)Fanttik’s product page lists 40 minutes of continuous running “under typical outdoor temperatures,” 4 presets and readings in PSI, kPa or bar. It needs charging, and the Fanttik X8 Apex review covers charge times.
For drivers on a budget who want nothing to keep charged, the AstroAI plugs into the car’s 12V outlet.
AstroAI 100 PSI Tire Inflator (CZK-3674)
A budget 12V plug-in tire inflator (model CZK-3674) with a digital gauge and auto shut-off.
Key specs
- Up to 100 PSI (6.9 bar)
- Plugs into the car's 12V socket
- Runs 10 min, then rests 10 min
Paid link
View on Amazon (opens in a new tab)Its manual lists 100W maximum power, auto shut-off and a 9.84 ft (3 m) power cord, and says to run it 10 minutes, then rest it 10 minutes. AstroAI sells several inflators under similar names, so check the model number. For the trade-offs, see cordless vs 12V tire inflators.
Charge the GB40 fully, put it in the kit with your tire gear, and fill in the rest from the full emergency kit checklist. Buying for someone else? See gifts for new drivers.
