Review: Compact and lightweight with bonus features - This lightweight, compact and portable jumpstarter is just what I needed. Will be using to jumpstart an old humvee. It also has features for flashlight with two additional hazard flashing white. This will be stored under the seat. Good for USB C charging too. Well-made and intuitive. Great for taking off road since it holds battery long time.
Review: Great peace of mind - 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.

### ⭐⭐⭐⭐⭐ Great for Jump Starts !!
*by J***Y on August 27, 2025*

This Lokithor J400 jump starter has already paid for itself because it saved me from being stranded by a dead battery. It is easy to use and easily starts my mid-size car battery. I can actually use it several times before it needs recharging. At least 4 or 5 times. Easy to apply and easy to charge with a USB charger. The flashlight also comes in handy in an emergency. It is also capable of charging a cell phone in an emergency. The cell phone charge rate is kind of slow compared to a standard ac charger but it does charge a cell phone. It was well worth the sale price that I got it at. I have already needed to use it for a jump start 4 or 5 times and it comes in handy especially when you are stranded.
