Unless you press the over ride, which cancels out the safety features, this little unit is safe enough even for me. Using the GB40 is very easy. My car had been standing idle for a month before using the GB40. When the gadget arrived I needed to power it from the mains for about an hour. I took it outside and managed to start my Diesel 2L on the second attempt. USE THIS MODE WITH EXTREME CARE. THIS MODE IS FOR 12-VOLT LEAD-ACID BATTERIES ONLY. BOTH THE SPARK PROOF AND REVERSE POLARITY PROTECTION FEATURES ARE DISABLED. PAY VERY CLOSE ATTENTION TO THE POLARITY OF THE BATTERY BEFORE USING THIS MODE. DO NOT ALLOW THE POSITIVE AND NEGATIVE BATTERY CLAMPS TO TOUCH OR CONNECT TO EACH OTHER AS THE PRODUCT WILL GENERATE SPARKS. THIS MODE USES VERY HIGH CURRENT (UP TO 1000 AMPS) THAT CAN CAUSE SPARKS AND HIGH HEAT IF NOT USED PROPERLY. IF YOU ARE UNSURE ABOUT USING THIS MODE, DO NOT ATTEMPT AND SEEK PROFESSIONAL HELP. Ok, I am no mechanic; I can just about show you where the wheels are on my car! So when it came to purchasing jump starter to actually start the car we were venturing into an alternative Universe. But along comes The NOCO GB 40 Boost. The most important feature to me is the safety feature. Believe me, when your not familiar with the workings of your car, this feature is vital. The 50% Charge LED will 'breath' on/off while charging and will be solid Red when the internal battery is 50% charged. Depending on the mode selection, the GB40 will have various levels of output and runtime. Selecting a lower power level when using the GB40 for extended periods of time will prolong battery life.
One step up, GB50 will jump-start vehicles’ engines up to 7.0 liters for gas, and 4.5 liters for diesel. It will take 30 jump-starts to empty its battery of power. NOCO also upped the flashlight’s strength to 200 lumens. This is great for those emergency situations in which a jumpstart doesn’t get your car started because of an underlying issue. When you have the Noco Boost in your car you’ll never have to worry about your phone dying. Its patented safety technology renders to reverse polarity protection and spark-proof connections allow safe jump-start of a dead battery in seconds. The powerful and high-quality battery booster functions easily in vehicles while doubling as a power source for recharging USB devices. When shutting down, GB40 changes modes from SOS to emergency strobe eventually before turns off. Why the NOCO Boost Plus GB40 Charger is a great choice:

Recharge your personal devices on the go, like smartphones, tablets, e-watches and more - up to 4 smartphone recharges. Noco Boost’s flashlight features seven different modes including emergency strobe and SOS. This makes it easier for other motorists to see you and easier to signal for help. The flashlight can be used for any situation when visibility is decreased and you need an extra source of illumination. The 25% Charge LED will 'breath' on/off while charging and will be solid Red when the internal battery is 25% charged. Try starting the vehicle. Most vehicles will immediately start. Some vehicles may require the GB40 to be connected for up to 30 seconds before starting. If the vehicle does not start right away, wait 20-30 seconds and try again. Do not attempt more than five (5) consecutive jump starts within a fifteen (15) minute period. Allow the GB40 to rest for fifteen (15) minutes before attempting to jump start the vehicle again.
The 25% Charge LED will slowly pulse "On" and "Off", when the battery is less than 25% charged. When the battery is 25% charged, the Red Charge LED will be solid. To turn the flashlight "On" and "Off", use the Power button with the light bulb icon. Press once to turn the flashlight "On" at 100% luminosity, again for 50% luminosity (within 3 seconds), again for 10% luminosity (within 3 seconds), again for SOS (within 3 seconds), again for Blink (within 3 seconds), again for Strobe (within 3 seconds) and again for "Off". If a light mode is not selected within 3 seconds, it will remain "On" in the current light mode, and the next selection will turn the flashlight "Off". Advanced Design – Our most advanced jump starter ever. Featuring high-discharge lithium technology for safe operation in any climate. A rugged and water-resistant enclosure rated at IP65. And an ultra-compact and lightweight design, weighing only 2.4-pounds.
When connected to a USB charger, no other charge LEDs will be illuminated. Once disconnected from the charger, all four (4) Charge LEDs will be illuminated when the internal battery is between 75%-100%, and the unit is powered "ON". The absence of a built-in display is compensated for by the charger's construction with high-quality materials, ensuring its reliability and durability over time. The RoHS certification indicates that the charger adheres to European Union regulations and is environmentally sustainable.
