Key Takeaways
- VANTRUE POWER JS2 at 50% off: The JS2 2500A unit is the deepest cut in the pool and handles a 6.0L gas or 3.0L diesel engine.
- GOOLOO A3 sits at the top of the category: The A3 3000A is currently the #2 bestseller in its category and inflates to 150PSI.
- Diesel coverage matters: Four of these seven units cover diesel engines up to 6.5L or larger, which is what you want for a half-ton or three-quarter-ton truck.
- Budget option under $50: The Tinyoak jump starter is the cheapest entry with an air compressor built in.
Memorial Day weekend is almost here, which means trucks across West Virginia are about to get worked. Camper trips to Seneca Rocks, gravel hauls for the new fence line, somebody towing a side-by-side up to a fire road that doesn’t see a tow truck on a good day. This is the time of year I start checking the battery in the F-150 and asking whether the kit in the back seat is still good or if it’s been quietly dying since deer season.
For this week’s WV Finds, I pulled together seven jump starters with built-in air compressors because the deals lined up across several trusted brands at once. VANTRUE POWER ran a 50% cut on the JS2, GOOLOO dropped the A3 below seventy bucks, and even the smaller names like Tinyoak and ZYcadmyx came down enough to be worth a look. Most of these will turn over a 6.0L gas or 3.0L diesel without complaint, and a couple step up to 8.0L or 9.0L territory for the heavier trucks.
I weighted this list toward units that genuinely handle diesel, because half of the truck owners I know around Morgantown drive a 6.7 or a 6.6 and a 2500A pack is going to disappoint them in February. Here’s what I’d put in the bed of the truck before the holiday weekend.
Which VANTRUE POWER jump starters stand out this week?
VANTRUE POWER is having the best week in the category. Both the JS2 and the JS3 are sitting at deep cuts with a 9-inch display, 160PSI compressor, and a 65W charging port that doubles as a power bank for a phone or a cooler fan.
VANTRUE POWER JS2 2500A
The JS2 2500A is the value play in the VANTRUE POWER lineup right now and it’s marked down by half. It covers 6.0L gas and 3.0L diesel, which is plenty for a half-ton truck or most SUVs. The 9-inch display is the part I keep coming back to since you can read PSI and battery voltage without crouching in the dark, and the nozzle storage compartment means you won’t lose the needle for the basketball at the boat ramp.
- 2500A peak, 6.0L gas / 3.0L diesel
- 160PSI air compressor with nozzle storage
- 9-inch display, 65W power bank
VANTRUE POWER JS3 3250A
If you’ve got a 3500 or anything pulling a diesel north of 6.0L, the JS3 is the one to grab. It runs a true 3250A and covers 8.0L gas or 3.8L diesel, with the same 160PSI compressor and large display as the JS2. It’s a limited time deal, so the markdown won’t sit there forever.
- 3250A peak, 8.0L gas / 3.8L diesel
- 160PSI air compressor, jump box light
- 9-inch display, 65W fast charge
How do the GOOLOO units compare for diesel trucks?
GOOLOO has been the default recommendation in this space for a few years and the A3 confirms why. It’s the current #2 bestseller in the jump starter category and the price has come down meaningfully this week.
GOOLOO A3 3000A
The GOOLOO A3 hits 3000A and covers a 9.0L gas or 6.5L diesel, which is genuinely useful for a 2500-series truck. The 150PSI auto-shutoff inflator is the feature I’d want on a road trip since you can set the target pressure and walk away. At under seventy bucks, this is the spot where I’d start if I didn’t already own a jump pack.
- 3000A peak, 9.0L gas / 6.5L diesel
- 150PSI auto-shutoff tire inflator
- Bestseller rank #2 in category
GOOLOO GP3000
The GP3000 is GOOLOO’s older 3000A model without the built-in compressor, and the discount this week is smaller. It still covers a 9L gas or 7L diesel engine and includes USB quick charge plus a Type-C port. Worth it if you already own a separate inflator and just want jump capacity for the truck and the tractor.
- 3000A peak, 9L gas / 7L diesel
- USB Quick Charge plus Type-C port
- No built-in air compressor
What about cheaper picks that still cover a truck engine?
The bottom half of this list is where I’d be careful. These are functional units with real discounts, but the bestseller ranks and brand history are mixed. Read the specs before you click.
S ZEVZO ET03 4000A
The S ZEVZO ET03 is the budget standout at well under sixty bucks. It’s rated 4000A and handles up to 8.0L gas or 7.0L diesel, which is impressive at this price. No air compressor on this one, so pair it with a separate inflator if you want both. The bestseller rank of #4 in the category suggests plenty of buyers are happy with it.
- 4000A peak, 8.0L gas / 7.0L diesel
- 74Wh capacity with LCD display
- Storage case and LED light included
ZYcadmyx 5000A
The ZYcadmyx 5000A unit advertises bigger numbers than its bestseller rank supports, so I’d treat the 5000A claim with some skepticism. That said, it pairs a 160PSI compressor with an SOS light and jumper cables in one box, which is convenient for a single roadside kit. Reasonable if you’re outfitting a backup truck or a teenager’s first vehicle.
- 5000A claimed peak, 9L gas / 8L diesel
- 160PSI air compressor
- Includes jumper cables and SOS light
Tinyoak 150PSI
Tinyoak’s unit is the cheapest entry on this list and the smallest discount, but it still covers 9.0L gas or 6.5L diesel and includes a 150PSI inflator with digital readout. The brand is new to me, so I’d consider this one for a beater or a farm truck where you want a backup pack and you’re not betting the whole rescue on it. The LCD display and built-in lights are decent for the price.
- 9.0L gas / 6.5L diesel coverage
- 150PSI digital tire inflator
- LCD display with built-in lights
Frequently asked questions
What size jump starter do I need for a diesel truck?
For a half-ton diesel, look for at least 2000A peak and engine ratings that cover 3.0L diesel or higher. For a 2500 or 3500 with a 6.6L or 6.7L diesel, you want 3000A or more and a diesel rating of 6.5L+, like the GOOLOO A3 or the VANTRUE POWER JS3. Cold weather drains amperage fast, so size up if you park outside through a West Virginia winter.
Do jump starters with built-in air compressors work well for truck tires?
Yes, if they hit 150PSI or higher. Most light truck tires run between 35 and 80 PSI, but larger trailer tires and some duallys go above 80, so you want headroom. The 160PSI compressors in the VANTRUE POWER units have enough capacity for most truck and trailer use, though they’re slower than a corded shop compressor.
How often should I charge a portable jump starter?
Top them off every three months even if you haven’t used them. Lithium packs lose charge slowly while sitting in a hot or cold truck cab, and a dead pack is useless on the day you need it. I set a reminder on the first of each season.
Are these jump starters safe for modern trucks with sensitive electronics?
The units in this roundup all include reverse polarity protection and overcurrent cutoffs, which is what you need for a modern truck with ECMs and infotainment systems. Follow the clamp order in the manual and you’ll be fine. GOOLOO and VANTRUE POWER both label their safety features clearly on the packaging.
The discount range this week ran from 18% on the Tinyoak unit up to 50% on the VANTRUE POWER JS2, with most landing between 30 and 40 percent. That’s a healthier spread than I usually see in this category, where the typical week is full of 15% nudges with one inflated original price thrown in for show. The original pricing on the VANTRUE POWER and GOOLOO units checks out against their normal sale floors, which I appreciate.
The standout for me is the VANTRUE POWER JS2 at half off. The 9-inch display is genuinely better than the postage stamp screens on the cheaper packs, and the 6.0L gas rating covers most of what I see in West Virginia driveways. If you’re running a heavier diesel, the GOOLOO A3 is the safer pick at #2 in the category with the bigger engine coverage. I’d skip the ZYcadmyx unless you specifically want the bundled jumper cables and SOS light setup, since the bestseller rank tells me buyers haven’t lined up behind it.
Memorial Day weekend usually pulls automotive prices either flat or a hair lower, so if you’re hesitating, I wouldn’t wait past the holiday. After that, jump starter pricing tends to drift back up until late summer when the back-to-school and fall road trip cycles kick in. If you missed it, my other automotive deals are still live, including portable air compressors that pair well with the no-compressor units above.
