Compact and Powerful
The GB40 is lightweight and powerful enough for my diesel engine. The only downside is the battery life when used extensively for device charging, but it recharges quickly.

Good Jump Starter, Could Use a Case
Works well for jump-starting and charging gadgets. I wish it came with a carrying case to keep everything organized, but otherwise, it's a great product.
