The two-line summary
If you drive a sedan, crossover, or minivan and want one box in the trunk that jumps the battery and tops off a tire, the GOOLOO A3 Jump Starter with Air Compressor is the smarter buy at $69.99. It's rated to 3000A and 9.0L gas / 6.5L diesel, pumps to 150 PSI at 35 L/min, and has 4,649 ratings averaging 4.4 stars behind it.
The GOOLOO A5 Jump Starter with Air Compressor is the step-up: 4000A and a 160 PSI ceiling for $119.99. Buy it if you're working around diesel trucks or big-displacement V8s and want headroom on both the clamp and the hose. Neither unit is a substitute for a dual-cylinder shop compressor or a full-size booster pack — these are glovebox-class roadside tools, and this comparison is built from listing specs and owner reviews, not independent bench testing.

How this comparison is scored
This head-to-head uses manufacturer listing specs and owner-review themes only — not bench fill-rate tests. Missing numbers stay n/a (not on file). Max PSI, claimed flow (CFM or L/min), duty-cycle notes, and carry weight decide the call; brand preference does not. I cover tire-pressure and roadside air tools as an editor — checklist against listings, not a lab visit.
Spec snapshot
Both units are 12V lithium-polymer jump packs with an integrated inflator. GOOLOO doesn't publish weight, watt-hour capacity, or continuous output for either model, so those cells read n/a rather than a guess. Amperage below is the listing's peak jump rating, not a continuous draw figure.
| Product | Price | Peak Jump Amps | Max PSI | Flow (L/min) | Weight (lb) | Rating |
|---|---|---|---|---|---|---|
| GOOLOO A3 Jump Starter with Air Compressor | 89.99 | 3000A | 150 | 35 | n/a (not on file) | 4.4 (4,649 ratings) |
| GOOLOO A5 Jump Starter with Air Compressor | 89.99 | 4000A | 160 | n/a (not on file) | n/a (not on file) | n/a (not on file) |
Where the A3 wins
Price is the obvious one, and it isn't close: $69.99 against $119.99, with the A3's historical low sitting at the same $69.99. That's a $50 gap for a tool most people use a handful of times a year.
The A3 also has the only real evidence trail here. 4,649 ratings at 4.4 stars is a sample you can actually read through, and the themes line up with the job: shop techs using it to replace a bulkier pack that struggled on cold starts, a Baja traveler leaning on the compressor for repeated puncture fixes on unpaved roads, and a family buying two for a Sienna and a Palisade. The listing also spells out inflation endurance — 45 minutes of continuous cordless run time, roughly 8 car tires per charge — which is the number I'd want before trusting a combo unit on a road trip.
One more A3 edge: the listing publishes its flow rate (35 L/min) and its full mode set (SUV, car, bike, ball, custom, with auto shut-off and a pressure readout). The A5's listing doesn't give a flow figure at all, so on paper the A3 is the easier unit to predict.
Where the A5 wins
Raw jump headroom. 4000A against 3000A, and a 160 PSI ceiling against 150. If your driveway holds a diesel pickup or a big V8, that margin is the whole reason to pay up — owner reviews describe it starting a 650CCA battery that other cars and older packs struggled with, and repeatedly rescuing a 5.3L Silverado.
The A5's inflation stories skew heavier too. One owner levels the tires on a Silverado and a Tahoe in short order and notes the battery dropping from full to half — a useful, honest data point about how much run time big tires eat. Another describes filling from about 10 PSI to 35 in under five minutes on a slow-leak tire. That's the kind of duty cycle a passenger-car owner rarely needs and a truck owner absolutely does.
What the A5 does not have is a rating on file. No star average, no review count — so treat the positive owner notes as a thin sample, not a consensus. There's also a 4/5 review describing three failed jump attempts on a battery that wasn't fully dead, which is worth knowing before you assume the extra amps guarantee a first-press start.
The tie-breakers
Both carry the same 18-month warranty per the listings, so that's a wash. Where they separate:
Bullets:
- Evidence volume: the A3 has thousands of ratings; the A5 has none on file. If you weigh owner feedback heavily, that alone tilts the decision.
- Hose and chuck practicality: the A3 ships with five nozzles and a pump tube for balls, bikes, and rafts; the A5's included accessory list isn't detailed in the data I have.
- Displacement fit: 9.0L gas / 6.5L diesel (A3) versus the A5's higher 4000A rating with no published displacement figure. If you're near the A3's ceiling, the A5 is the safer bet on amps alone.
Pick one — and who should skip both
Buy the A3 if you drive a gas sedan, crossover, or minivan, want a proven combo box under $70, and care that thousands of owners have already stress-tested the thing. Buy the A5 if you're regularly around diesel trucks or large V8s and the extra 1000A and 10 PSI are worth $50 to you — and you're comfortable buying with a thinner review record.
Skip both if you need to air up an RV to 80 PSI, run a dual-cylinder compressor for repeated truck-tire work, or want a dedicated inflator with a published flow rate and a long hose. A combo jump pack is a compromise: the compressor is convenient, not fast, and the clamp leads are short. For a pure tire tool, look at a standalone 12V inflator; for battery health and storage habits, our guide on jump starter care covers the recharge-every-three-months rule both GOOLOO manuals repeat.
What owners report
Theme summaries only — no star headers, no pasted quotes.
- GOOLOO A3: Shop and road-trip reliability — techs use it where bigger packs bog down; a Baja driver relies on the compressor for repeated punctures; one family unit overheated and was replaced under warranty.
- GOOLOO A5: Truck-tire duty — owners report fast fills on Silverado, Tahoe, and diesel tires, with battery dropping to about half after leveling big tires; one 4/5 reviewer had repeated no-start attempts despite a full charge.
