The short version: three brands, three different priorities. NOCO is the safety-and-support benchmark the reviews back most consistently — the biggest review base and a warranty owners actually praise. GOOLOO is the value powerhouse, handing you far more cranking amps and battery per dollar. AVAPOW is the raw-capacity pick, with the highest headline amp figure and a battery that doubles as an emergency power bank. There's no single "best" — only the right pack for your engine and your budget.
This is a straight head-to-head. If you want the wider field ranked, our best portable jump starter guide covers more packs, and the jump starters hub explains where a booster fits alongside chargers and maintainers.

How We Compare Them
We don't jump-start cars in a lab and score them — we read the crowd. For each brand we pull together the aggregated Amazon rating, the volume of reviews behind the flagship pack, and the recurring themes owners raise: whether it actually starts their engine in the cold, how the clamps and safety lights behave, how much capacity survives a year of trunk life, and how the company responds when a unit fails. Where thousands of reviewers repeat the same thing — "started my truck first try," "support replaced it fast" — that consensus is the real signal. Prices move around; the verdicts are built on what owners consistently report over time.
Cranking Power: The Amp Numbers, Honestly
On the spec sheet, this looks like a blowout — 1000A for the NOCO GB40, 4000A for the GOOLOO GP4000, 6000A for the AVAPOW. But peak amps are a headline, not the sustained current your starter draws, so read them with care. The reality owners report: the GB40's 1000A comfortably starts most 4- and 6-cylinder gas engines, which is exactly why it has 80,000-plus reviews and so few "wouldn't crank" complaints. Step up to a big V8, a loaded truck or a diesel and the extra output of the GOOLOO and AVAPOW genuinely earns its keep — reviewers with larger engines specifically praise the bigger packs for cranking where a smaller one hesitates. Buy for your biggest engine, not the biggest number.
Battery Capacity: GOOLOO and AVAPOW Go Long
Capacity is where the value brands flex. The AVAPOW carries the largest battery of the three, and the GOOLOO GP4000 isn't far behind — both give you more consecutive jump attempts and far more runtime as a power bank for phones, tablets and work lights. Owners who camp, overland or keep a pack for family emergencies lean toward these two for exactly that reason. The NOCO GB40 is the compact of the group: smaller battery, glovebox-friendly size, and enough capacity for its job. If your booster doubles as your emergency power supply, capacity tips the scales toward GOOLOO and AVAPOW; if it lives in the door pocket for the occasional dead battery, the NOCO's size is the feature.
Safety and Support: Where NOCO Earns Its Price
All three ship the protections that matter — reverse-polarity, short-circuit and spark-proof clamps — and all three carry thousands of clean reviews, so none is a gamble. What separates NOCO is the length and scrutiny of its record: a decade-plus in the category, the largest review base by a wide margin, and support that owners repeatedly single out as the reason they'd buy again. GOOLOO and AVAPOW match the safety features and earn solid marks, but they're younger names with shorter histories. Think of it like a long race — the newcomers are quick, but NOCO has the finishing record that makes cautious buyers comfortable paying a little more.
The Verdict: Pick by Engine and Budget
There's no loser here, only three clear use-cases — so match the pack to your situation rather than chasing one "winner."
- Pick the NOCO GB40 if you drive a typical car and want the most proven, best-supported pack in the category. It's compact, safe, and backed by the biggest review base here — the high-consensus choice, and our overall pick.
- Pick the GOOLOO GP4000 if you want the most cranking power and capacity per dollar, especially for a big gas or diesel engine. It's the value powerhouse for buyers who prioritize output over brand history.
- Pick the AVAPOW 6000A if you want maximum capacity and the highest headline amps, and you'll use it as an emergency power bank as much as a jump starter. It's the raw-spec pick for trucks and off-grid backup.
The cautious move is the NOCO; the value move is the GOOLOO; the "one pack for the truck and the campsite" move is the AVAPOW.
The Three Jump Starters, Side by Side
Best for most drivers — proven safety, reliability and support
- 1000A — starts most 4- to 6-cylinder gas engines
- Spark-proof, reverse-polarity protected
- Huge review base and strong warranty support
- Compact enough for the glovebox
Why buy it: the pack the reviews back most consistently — the highest-volume safety reputation in the category, plus support owners actually praise when a unit fails.
Best for big gas and diesel engines on a budget
- 4000A — cranks large V8 and diesel engines
- USB-C PD in/out, doubles as a power bank
- Bigger battery than the GB40
- Chunkier to store than the NOCO
Why buy it: the value powerhouse — far more cranking amps and battery capacity per dollar, if you can live without NOCO’s brand-length track record.
Best for trucks, diesels and doubling as an emergency power bank
- 6000A peak — the highest headline figure here
- Large capacity for multiple starts and device charging
- Bright built-in work light
- Newest brand of the three — shorter track record
Why buy it: the raw-capacity pick — the most amps and mAh on paper, ideal if it also serves as your emergency power bank for phones and lights.
