Cobra Jump Pack Portable Charger

Perfect fix with the cobra crane backpacker. I carry it like a bag pack and put other small things in it.

The perfect, and amazingly power pack of size that can jump from truck to truck and 4 wheeler with me. It possibility just keep getting better.

A third party charger isn't able to take this battery from zero to usable, so make sure you jump-start it using the official Leica charger.

At first, before reading the directions, I was disappointed that the jump pack could not turn over my car. Dead battery and all. However, after understanding the directions for use on a DEAD battery the pack brought engine to life better than a brand new battery ever had. Pricy, but worth it.

I live in New England, winter weather is brutal, single-digit temps for days. This GB150 jump pack starts ALL the vehicles and equipment that's housed outside and comes back for more. We're talking diesel & gas engines, quick charging of smartphones, tablets, even rechargeable flashlights. Very rugged, well designed, and easy to operate. A high-quality functional tool you can't afford to be without. Buy a quality jump pack, it will be there for you when you need it! 5 stars...

I opted for the aluminum - big jump in price if you're going for the carbon fiber. It's lightweight and portable enough for my purposes. I use a spotting scope and the tripod, in combination with the 128rc head, is an excellent and cost efficient combo.

I forgot to pack my charger. I'll never be without a spare one again.

1st NANO-VBR98 I bought for my Panasonic AG-CX350 camcorder was back in 2021. I love it! Still works great. 2nd one I bought last month would not charge. Sent it back to B&H for a replacement. Got the replacement and IT would not charger either. Anxiety set in. Contacted B&H customer service for help. They communicated a few times with Core SWX Tech support about the problem and finally got a good answer from them that these batteries need what Core calls a "Jump Start" procedure when initiating the 1st charge. This trick is putting it on and off the charger, back and forth numerous times before the charger "sees" it and starts charging it. Once the charge light stays a solid orange and is not blinking, the "Jump Start" is successful and the bottom green battery level indicator light on the actual battery will blink and that's a good comforting sign that the battery will be successfully charged completely from that point on with the charge light turning the normal solid green when full charge is achieved.

Works great. The official charger was the only one able to jump start the battery though, but after the initial little bit, I was able to confirm that it charged more than 1800mAh.
