Best Jump Starters

Pros

• +2,000A rating covers gas engines up to 8.0L and diesels up to 6.0L — V8 pickups, SUVs, boats
• +UltraSafe clamps: spark-proof, reverse-polarity protected, with manual override for fully dead batteries
• +400-lumen flashlight with SOS and strobe; 12V output runs a tire inflator

Cons

• −About 5 lb and the size of a hardcover book — a bigger glovebox footprint than the GB40
• −Micro-USB charging on most stock; full recharge takes hours from a wall brick

Pros

• +4,250A rating covers gas up to 10.0L and diesel up to 8.0L — heavy-duty pickups, RVs, farm equipment
• +65W USB-C in and out: recharges the pack in a few hours and fast-charges laptops and phones
• +500-lumen flashlight; rubberized IP65 housing with the same UltraSafe clamp protection as the rest of the line

Cons

• −~7.5 lb — this lives under a seat or in a toolbox, not a glovebox
• −Priced like a budget battery charger and a GB40 combined

Pros

• +1,250A rating covers gas engines up to 6.5L and diesels up to 4.0L — more headroom than the GB40 on a cold V6
• +60W USB-C Power Delivery in and out: full recharge in about 48 minutes, and it fast-charges a phone or laptop
• +'0% to boost in 5 minutes' — a few minutes on a charger is enough to attempt a jump if you've let it run down

Cons

• −Same -4°F operating floor as the rest of NOCO's line — no cold advantage over the GB40
• −Still not a V8 or big-diesel pack; a cold 5.7L truck wants the GB70

Pros

• +2,500A rating covers gas engines up to 8.5L and diesels up to 6.5L — a genuine step above the GB70's 8.0L/6.0L
• +60W USB-C PD in and out: full recharge in about 1.8 hours, boost-ready in 5 minutes, and it fast-charges a laptop
• +400-lumen flashlight with 7 modes including SOS and strobe — brighter than the GB40/GB70's units

Cons

• −Same -4°F operating floor as the rest of the NOCO line — no cold-weather edge over the GB70
• −A real jump in price over the GB70 for a rating most drivers won't need

Pros

• +1,000A rating starts gas engines up to 6.0L and diesels up to 3.0L
• +Compact and 2.4 lb — fits a glovebox or door pocket
• +UltraSafe spark-proof, reverse-polarity-protected clamps with manual override

Cons

• −Marginal for V8s and any engine at deep sub-zero temperatures — size up if that's you
• −Micro-USB charging input on most units; slow recharge

Pros

• +Automatic pre-heat below 32°F and a -40°F operating rating — no other pack in this guide comes close
• +2,000A with an 8.5L gas / 6.0L diesel rating; AutoGuide's test cranked a 6.5L diesel and started a dead Subaru seven times
• +74Wh (20,000mAh) cell — a real power bank, and reserve for repeated cranks on a stubborn engine

Cons

• −Pre-heat takes up to a minute before the READY indicator and uses some of the charge you're about to need
• −Hulkman is a younger brand than NOCO or Clore — fewer years of owner data on longevity

Pros

• +2,000A with the same 8.0L gas / 6.0L diesel rating as the GB70 — full-size trucks and SUVs are covered
• +Compressor is properly specified: 67 L/min, 100 psi max, 280W motor, tires up to 35 inches, digital preset with auto-shutoff
• +60W USB-C in and out — recharges from a wall brick or fast-charges a laptop; 100-lumen flashlight

Cons

• −About 7 lb and the size of a small toolbox — this lives in the trunk, not a door pocket
• −Compressor duty cycle is 5 minutes on / 30 minutes off: fine for one flat, slow for four winter tires

Pros

• +6,000A peak rating with an all-gas/12.0L-diesel engine ceiling — the highest coverage of any pack in this guide, on paper matching or beating the NOCO GBX155
• +99.9Wh (27,000mAh) cell — enough capacity for repeated cranks and genuine power-bank duty
• +100W bidirectional USB-C: 0–100% recharge in about 1.4 hours, and it fast-charges a laptop

Cons

• −A brand-new tier from GOOLOO with no multi-year reliability record — treat it the way you would the WOLFBOX MegaVolt24, not an established NOCO
• −6,000A is a manufacturer peak-amp figure on the same unregulated honor system as every budget pack's rating; expect real-world performance closer to a strong 4,000A-class pack

Pros

• +4,000A rating covers gas and diesel engines up to 10.0L each — matches the GBX155's diesel-truck ceiling at well under a third of the price
• +88.8Wh (24,000mAh) battery doubles as a substantial power bank on top of jump-starting duty
• +65W USB-C fast charging: full recharge in under two hours

Cons

• −A much newer brand than NOCO or Clore, with a few years of reviews rather than a decade of owner data
• −4,000A peak is still below the GBX155's 4,250A rating, so it's a value alternative, not a strict upgrade

Pros

• +Reliably starts V6 and V8 gas engines; GOOLOO rates it for gas up to 10.0L and diesel up to 8.0L (treat as generous)
• +Large 26,800mAh capacity — a real power bank with USB-C PD and USB-A outputs
• +Smart clamps with reverse-polarity, short-circuit, over-current, and over-temperature protection

Cons

• −'4,000A' isn't comparable to NOCO's ratings — it's a strong 2,000A-class performer in practice
• −Clamps and housing feel less robust than NOCO's; more owner reports of failure after 2–3 years

Pros

• +1,700 peak / 425 cranking amps of sustained lead-acid output — excellent on cold, hard-starting engines
• +46-inch #2 AWG clamp leads reach any battery, including trucks and boats
• +Built-in automatic charger — leave it plugged in and it's always ready

Cons

• −18 lb and bulky — a garage or truck-bed tool, not something you carry in the cabin
• −Needs recharging every 90 days or so (lead-acid self-discharges)
