Green Lion 12V Jump Starter 12000mAh is now in stock at Mascom International for KSh 12,300, available today at our Nairobi CBD store inside Old Mutual Building, First Floor Room 4, Kimathi Street. The unit jump-starts vehicles up to 20 times per full charge across a 600-to-12000A current range, runs a built-in 150 PSI air compressor with 4 inflation modes, doubles as a 12000mAh power bank with two USB-A ports plus USB-C fast charging, and includes a 3W LED flashlight with a digital display for live readings. The model code is GN12VJUSTBK, finished in black with PC and ABS housing.
Built for Kenyan motorists who cannot afford to be stranded Uber and Bolt drivers running 12-hour shifts, matatu owner-operators, long-distance Mombasa Road haulers, NGO field staff covering Turkana and Marsabit routes, weekend Maasai Mara self-drive travellers, and family car owners parking overnight in Karen or Runda. Dead batteries, slow leaks on rough Kiambu roads, and unreliable petrol-station compressors create real income loss and safety risk. The Green Lion 12V Jump Starter 12000mAh handles all three problems from a single unit small enough to fit under any driver's seat.
Mascom International stocks the Green Lion 12V Jump Starter 12000mAh as part of our automotive accessory range, with genuine packaging, the original 12-month manufacturer warranty, and accurate specifications verified against Green Lion's official product listing. Customers across Kenya rely on us for honest pricing on roadside equipment they actually need. Walk into our Kimathi Street store to test the inflation modes and digital display in person, or order on +254 708 852 521 for same-day pay-on-arrival delivery within Nairobi.
Common Questions About the Green Lion 12V Jump Starter 12000mAh
What can the Green Lion 12V Jump Starter 12000mAh actually start?
The Green Lion 12V Jump Starter 12000mAh handles 12V vehicle batteries with a current range of 600A to 12000A, which covers the full range of cars on Kenyan roads. That includes saloon cars like the Toyota Premio and Mazda Demio, SUVs including the Toyota Prado and Mitsubishi Pajero, light pickups such as the Hilux and Navara, and motorcycles including boda boda Honda and TVS models. The unit jump-starts up to 20 times on a single full charge, which means a single overnight charge covers a full week of emergency calls for ride-hail drivers.
How long does the battery hold charge in storage?
Green Lion does not publish an official shelf-discharge figure, but lithium battery jump starters of this class typically retain 70 to 80 percent of capacity after 3 months of unused storage. Mascom International recommends recharging the Green Lion 12V Jump Starter 12000mAh every 2 to 3 months when stored in your boot, especially during Kenya's hot months between December and March when interior car temperatures push lithium self-discharge rates higher. The digital display shows current charge level so you know exactly when a top-up is needed.
How does the 150 PSI air compressor compare to petrol station pumps?
The built-in air compressor reaches 150 PSI peak pressure, which is more than enough for any passenger vehicle since standard car tires run between 30 and 40 PSI and even loaded pickup tires rarely exceed 65 PSI. The 4 preset inflation modes let you set target pressure for cars, motorcycles, bicycles, and sports balls without manual monitoring the compressor stops automatically when the target is reached. Petrol-station pumps along Thika Road or Mombasa Road are often broken or inaccurate, so carrying your own removes that dependency entirely.
Can I use it to charge my phone or laptop?
The Green Lion 12V Jump Starter 12000mAh doubles as a 12000mAh power bank with 44.4W total output across two USB-A ports plus one USB-C port that supports fast charging both in and out. A typical Samsung Galaxy A series phone with a 5000mAh battery gets roughly 2 full charges from this unit, while an iPhone 15 with a 3877mAh battery gets close to 2.5 charges. Laptop charging via USB-C works for compatible 45W-class machines like the MacBook Air M2 during short top-ups, though it is not a primary laptop charger.
How long does it take to recharge the jump starter itself?
A full recharge from 0 to 100 percent takes about 3 hours via the USB-C input port using a compatible fast charger. Mascom International recommends pairing the unit with a 45W or higher USB-C wall charger to hit that 3-hour figure slower chargers like a 5W phone brick will extend recharge time to 8 hours or more. The digital display shows recharge progress in real time, so you always know when the unit is ready for service again.
Is it safe to use on my car battery without damaging the electronics?
Yes. The Green Lion 12V Jump Starter 12000mAh includes built-in safety protections covering reverse polarity, short circuit, over-current, over-voltage, and over-temperature scenarios. These protections prevent the wrong-terminal mistakes that can fry a modern car's ECU on older cable-style jumper systems. Mascom International still walks customers through correct clamp procedure when they collect the unit — red to positive, black to negative or chassis ground and the product includes a user manual with step-by-step instructions in English.
What makes Green Lion different from cheaper jump starters on Jumia?
Green Lion is an established UAE-based accessory brand with a multi-country regional distribution, not an unbranded import. Cheaper KSh 4,000 to KSh 7,000 jump starters circulating on Kenyan online marketplaces often inflate capacity claims (advertising 30000mAh when the cell is actually 6000mAh), lack genuine safety certifications, and ship without warranty backing. The Green Lion 12V Jump Starter 12000mAh ships from Mascom International with verified specifications, a 12-month manufacturer warranty, and direct after-sales support from our Nairobi CBD service desk.
Will it work for diesel pickups and 4x4s?
The 600 to 12000A current range covers most 12V diesel engines including the common Kenyan workhorses Toyota Hilux 2.4L diesel, Mitsubishi L200, Isuzu D-Max, and Land Cruiser 70-series variants up to roughly 3.0L diesel. Larger 4.5L diesel engines like the Land Cruiser V8 sit at the upper edge of the unit's capability and may require a colder-weather boost cycle to start. For heavy commercial trucks running 24V systems, this unit is not the right tool those need dedicated 24V boosters.
