I have just got through using it twice to jump start a MF 135 diesel tractor that had an old /totally drained battery. It didn't stagger a bit and jumped the tractor within 1-1-1/2 seconds and did it in a powerful/strong/solid manner. This thing is really impressive and I just hope that it gives me this type of performance for an acceptable amount of time (i.e...long enough that I feel I got my moneys worth). As of now, I'd recommend it to all my friends/relatives. NOTE...the only "Ah Man" moment about the purchase was that within 1-2 days of receiving it, I saw that it had went on sale for 33% off the original price I paid $89.95...it dropped down $30.00 to $59.95. I really wish that the vendors (not necessarily desertcart) would honor the discount/sale price, especially if it goes down while the item is in transit to your delivery address. ============== 11-29-25 UPDATE...STILL WORKING GREAT...use it 2-3 times every two weeks to jump start the 1971 MF tractor with the Perkins diesel engine and it's still works like a champ!!! ============== 04-25-26 UPDATE (OVER A YEAR NOW)...STILL WORKING LIKE A CHAMP...I continue to use it 1-2 times every two weeks to jump start my Dad's 54 year old Massey Ferguson tractor (Perkins diesel engine). It has a battery that can't be charged and alternator that is not working. THIS PRODUCT IS ONE OF THE BEST BUYS GOD HAS BESSED ME WITH...funny thing is that I bought it to keep in my Harley Low Rider saddlebags. Review: Powerful jump starter! - I desperately needed a jump starter battery for a car I barely drive and was tired of having to trickle charge it all the time so I purchased this jump starter. Overall impression is this thing is powerful and easy to use right out the box. Once connected to the car battery it will automatically jump start and let you know when the car is ready to be started. This thing is very useful to have in your trunk for emergencies, highly recommended to everyone! ## Features - Start Dead Batteries Instantly – Jump start even completely drained batteries with up to 2000A peak current.

Overall impression is this thing is powerful and easy to use right out the box. Once connected to the car battery it will automatically jump start and let you know when the car is ready to be started. This thing is very useful to have in your trunk for emergencies, highly recommended to everyone! ### ⭐⭐⭐⭐⭐ Great peace of mind *by C***C on December 7, 2025* Bought this over the NOCO after seeing reviews and videos. I have a Viking jump pack at 1000a and it is more expensive than this unit. I have used the 1000a to jump all of our vehicles when needed, including my motorcycle and my lawn mower, so this unit shouldn't have any issues with anything I throw at it. Lightweight, compact and easily stores in your vehicle. Bought this to keep in my truck. I like being able to jump start the vehicle without needing another vehicle to use jumper cables. Keeps you self-sufficient and gets you out of a jam if you find yourself alone in a remote area. Charges quickly and doesn't lose charge over time like other traditional jump packs. Like other lithium jump packs, they do recommend that you charge the unit every three months to extend the life of the batteries in the unit. Pretty standard. ## Frequently Bought Together - LOKITHOR J400 Jump Starter with ConnectMax Tech, 2000A 12V Battery Jumper Starter Portable, Lithium Jump Box and Jump Pack for Up to 8.0-Liter Gas and 6.0-Liter Diesel Engines, Smart Digital Screen - LOKITHOR J-Series Storage Bag EVA Protection Case for J400/J401/J401X/J402/J1350 PRO/J2250 PRO/JP400 LOKITHOR Battery Jump Starters - LOKITHOR JP400 Jump Starter with Air Compressor, 2500A 12V Car Battery Jumper Starter Portable (8.5L Gas/6.5L Diesel) with ConnectMax Tech, 150PSI Tire Inflator, Auto-Shutoff & Dynamic Dwell --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/628772972-j400-portable-jump-starter-12v-2000a-lithium-battery-booster-connectmax](https://www.desertcart.kg/products/628772972-j400-portable-jump-starter-12v-2000a-lithium-battery-booster-connectmax) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-06-07*
