10000mAh 12V portable jump starter
Anyone supplying roadside and fleet maintenance kits knows this recurring pain point: mechanics carry separate jump packs and tyre inflators. Two devices take up precious van space, easy to misplace, and add extra inventory overhead for fleet managers. We built the JSP-A3 as an all-in-one 12V emergency unit combining lithium jump starting and a built-in tyre air compressor. It delivers up to 500A peak surge for engine cranking and inflates tyres to a maximum 140 PSI. This is our workhorse emergency pack built specifically for roadside assistance teams, fleet service technicians, and long-haul drivers who want one heavy-duty tool in the vehicle instead of two.
Clarification for spec buyers: Peak current is an instantaneous short burst, not sustained cranking current. It is sized for most standard petrol and light diesel 12V engines.


core selling points

Dual-function design: jump start + tyre inflation, one unit only
400A / 500A peak instantaneous surge handles most common 12V petrol and light diesel engines. Once the vehicle fires up, the integrated 17mm cylinder air compressor takes over for tyre top-ups, up to 140 PSI. No need to haul, store and track a separate portable inflator on service calls.
High lithium capacity for back-to-back service jobs
We offer two capacity variants: 8000mAh and 10000mAh. A full charge supports roughly 15–30 jump starts, which matters for mobile teams who attend multiple breakdown calls in a single shift. It removes the stress of running flat halfway through a morning of roadside jobs.


Digital preset pressure with auto shut-off
The clear LED digital readout shows remaining battery level and live tyre pressure. Technicians can key in the target PSI before pumping. Once the preset pressure is hit, the compressor cuts out automatically, eliminating over-inflation risk - a small detail that reduces costly tyre damage claims.
Long-cycle lithium pack with low-maintenance storage
The internal lithium cell is rated for 1000 charge cycles at standard operating DOD. Fleet owners appreciate this: the unit can sit stored in service vehicles for months between uses, only needing a top-up via USB every 3–6 months to preserve cell health.

FAQ
Q: Can the air pump inflate a completely flat SUV tyre from 0 PSI?
A: Yes, it can inflate from 0 PSI up to the 140 PSI maximum. That said, filling a large, fully deflated tyre takes several minutes. Follow duty-cycle guidance: pause and let the compressor cool if it becomes hot, to protect the motor and avoid thermal shutdown.
Q: How do I know when to recharge the jump starter?
A: The digital display shows real-time remaining battery. We recommend recharging once the reading drops below 20%. For long-term fleet storage, top up the unit every 3 to 6 months.
Q: Does it come with a carrying case?
A: Yes, each unit ships with a dedicated storage bag to organise the clamps, air hose and main unit inside service vehicles.
Q: What engine types can the 500A peak version start?
A: The 500A peak surge variant suits most standard petrol and light-duty 12V diesel passenger & light commercial engines. It is not designed for large heavy-duty truck diesel engines. Contact us if you need higher-output fleet jump packs.
Q: What is the compressor's recommended duty cycle?
A: This is an intermittent-use emergency compressor, not a continuous workshop air pump. We recommend maximum 8–10 minutes of continuous pumping, followed by a cooling break before restarting.
Q: Can we get OEM branding and bulk packaging for fleet tenders?
A: Yes, we support custom branding and bulk neutral packaging for fleet operators and roadside service distributors. Send your tender specification for a custom quote.
