Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

Buying guide: the best jump starter for atv

Peak amps for an ATV

An ATV engine is small, so even the 2000A LOKITHOR here is plenty on paper; the five listings range from 2000A to 10000A peak. Higher peak current helps a deeply discharged battery accept the start, which is what the force start modes on the Unlazin and ANFLAG are for. Match the pack to your engine size from the listing, not just the peak number.

Battery capacity and starts

Capacity decides how many starts you get and whether the pack doubles as a power bank. The LOKITHOR lists 6400mAh and up to 25 starts per charge; the TREKURE lists 26800mAh and 1000+ charging cycles; the ANFLAG lists 16000mAh and 59.2Wh. A bigger pack is heavier: the ANFLAG bullets say 4.85 lb against a 1.29 kg spec table figure, so trust the bullets.

Extras that earn their space on a trail

Two packs here add a 160 PSI tire inflator with auto shutoff, the TREKURE and the ANFLAG, and the ANFLAG adds a 165L/min blower. LED flashlights run from 300 lumen to 800LM across the listings. For an ATV that lives on trails, an inflator matters more than a 5.5 inch screen.

What size pack fits in an ATV’s storage

ATV racks and under-seat boxes are small, so the listed dimensions matter. The LOKITHOR J400 is the lightest here at 450 g, measuring 3.39 by 6.89 by 1.69 in, and it is the natural choice for a machine with no room to spare. The Unlazin X8 is the slimmest, at 1.65 by 3.54 by 7.52 in. On the larger end, the TREKURE lists 8.7 by 2.13 by 5.59 in at 1.09 kg, the ANFLAG 9.13 by 5.43 by 2.8 in at 1.29 kg, and the fmooostore 10 by 6 by 8 in with no stated weight. If the pack rides on a rear rack, check the maker’s dimensions against your storage box before you buy, and remember the inflator models also need room for the air hose and nozzles.

Charge retention between seasons

A jump pack is only useful if it holds charge while the ATV sits. The TREKURE lists over 1000 charging cycles for its 26800mAh cell, and the ANFLAG recommends charging every 4 to 5 months when the pack is idle. Stated capacities run from 6000mAh (fmooostore) to 6400mAh (LOKITHOR) to 16000mAh (ANFLAG) to 26800mAh (TREKURE). A bigger stated capacity does not guarantee more starts; the only stated starts-per-charge figure here is the LOKITHOR’s up to 25. Keep the pack indoors over winter rather than in an unheated shed, and recharge on the schedule the maker gives.

For rack mounting, stated weights matter too: 450 g for the LOKITHOR, 1.09 kg for the TREKURE, and 1.29 kg for the ANFLAG. The fmooostore and Unlazin listings state no weight. A heavy pack bouncing on a trail is a pack that works loose, so use the carrying case when the listing includes one, like the rugged case the ANFLAG ships with.

Certifications and safety

Only the LOKITHOR states CE and UL. The others describe protection layers instead: the TREKURE lists 10 protection functions and V0 flame-retardant housing, the ANFLAG 10+ protections and V-0 housing, the fmooostore 10-layer protection, and the Unlazin smart clamps with buzzer alerts. Nothing here is a substitute for reading the manual before the first start.

Warranty terms, stated or not

Four listings state a warranty term: TREKURE and Unlazin and ANFLAG at 2 years (or 24 months), and LOKITHOR at 1 year. The fmooostore bullets promise 24-month support against a 90 day spec table figure; trust the bullets. Keep the pack charged between seasons so the warranty question never comes up.

Use as directed. Connect red to positive and black to a clean ground point away from the battery, in that order, and reverse when removing. Keep the pack and its clamps dry, never short the clamps together, and let the pack cool between jump attempts. Charge the pack as the maker directs so it is ready at the trailhead.

Frequently Asked Questions

Will a 2000A jump starter start an ATV?

The LOKITHOR lists 2000A peak and names ATV in its compatibility list, with up to 25 starts per charge. An ATV battery is small, so the listed engine support matters more than the peak number; check that the listing names your vehicle type.

What is a force start mode?

Several listings here describe a boost or force start function that pushes current to a battery too low for a normal start to recognize. The Unlazin and ANFLAG both list one, and the TREKURE lists a FORCE START function too.

How many times can one charge start a vehicle?

The LOKITHOR states up to 25 starts per charge. The other listings give capacity instead: 26800mAh, 16000mAh and 6000mAh. Real starts depend on temperature and how discharged the battery is.

Can I charge my phone from a jump starter?

The TREKURE lists dual USB output up to 18W, the Unlazin lists a QC3.0 USB-A port and a 5V/2A port, and the ANFLAG lists dual USB with QC and AFC fast charging. They double as power banks, which is useful on multi-day rides.

Do jump starters work in the cold?

The TREKURE and ANFLAG list a -4°F to 140°F operating range, and the Unlazin the same -4°F to 140°F range. Cold still reduces any battery’s output, so keep the pack inside the cab or your jacket rather than in an unheated box.
