    Quality Portable Car Jumper w/ a few shortcomings
    To echo what others have said in their reviews, this is a quality product. It looks exactly as described and function exactly as described. It's sturdy, feels premium, and appears that it will hold up to any drops or scrapes that may happen to it. Those qualities earn it four stars. The reason why I do not rate this product five stars is for two reasons. The first being that it does not include a a power brick with the product, only a power cable. You're left to your own devices to borrow one from another appliance or buy one. The latter reason being that it uses Micro-USB B as the connector. In 2019, it's expected for a product to use USB C-Type over the inferior Micro-USB B connector. These are two pretty minimal quirks though, so I'm happy to give it four stars. Overall, great product.

    First of all, it looks very well built, looking like a normal flashlight and most importantly, it works. I bought it in case I ever needed a jump, but I really didn't know how to test it, until I really needed it. And thank Lord it did work, because my 13 year old car just wouldn't start after I got gas at a gas station. And I didn't even have to read instructions, it was intuitive enough. Every old car owner needs this. And best of all it functions as a car charger.

    I bought this for my mother so that I can have peace of mind knowing that she will never be stranded because she needs a jump to start her car and she also does not need to rely on strangers to help her. It is very compact so is easy to carry in the car, or even in her purse if she is traveling with someone else. It is easy to use and works great!

    Received the unit with 75% charge. Charged it to 100% in about 3 hours. Next morning started a car with a fully dead battery 3 times!!! The first 2 times the engine died when the accelerator was released. After those three starts it was still showing 100% charge (4 lights). I love this very useful gadget!!!

    Haven't used it yet, and hope I won't need it, but it sure adds peace of mind.

    Minor points missing from the instructions:
    - When finished charging, blue lights turn off
    - Charge level LED's turn off after 1 minute of inactivity
    - Doesn't mention that the slow strobe mode of the flashlight is Morse code for SOS (this is mentioned on the box)
    - Why do the 2 USB ports have different power levels? (1.1A and 2.1A)

    Again, minor points, and they don't detract from the functionality.

    Update 8-21-18 Battery died today (I knew it was failing), but it died so completely that dashboard lights wouldn't come on.
    From the product description: "Use the boost button when you need to jump start a low voltage or fully discharged battery."
    From the instructions for the Boost button:
    - Note: A discharged car battery (Low Voltage) will trigger the PBJ300's [sic - I have the PBJ700] Low Voltage Protection" (indicated by no light).
    - Press and hold Boost button for 3 seconds
    - Jump start indicator light will turn Green

    But my light Jump start indicator light was blinking red. This indicates that "Jumper Starter has low battery".
    That's why I give this device one star - my PBJ700 was fully charged and the 4 power lights indicated this.

    I bought this based on the review of a motorcycle channel. I have jumped vehicles up to V8 motors with this. I jumped three motorcycles and one car before having to charge since it was at 50% capacity. It also sits in the saddlebag of my motorcycle, which sits outside, to be available when needed.
