The GB50 is equipped with advanced safety features to protect against reverse polarity, sparks, overcharging, overcurrent, and short-circuits. It has spark-proof technology and reverse polarity protection, making it safe and easy to use even for beginners. But how does it hold up when you’re out adventuring? One thing Alex found really useful was the built in 200 lumen LED flashlight (it has some decent modes, including flashing and emergency SOS) and the ability to charge phones or cameras via the USB ports — this thing is definitely more than just a jump starter. When recharging, the charge level of the internal battery is indicated by the Charge LEDs. The LEDs will slowly pulse 'On' and 'Off' and become solid until all four Charge LEDs are on. When the battery is fully charged, the Green 100% LED will be solid, and the 25%, 50% and 75% Charge LEDs will turn "Off". From time to time, the Green 100% LED will pulse indicating maintenance charging is occuring. In addition to its jump-starting capabilities, the NOCO Genius Boost XL GB50 also functions as a portable power bank. It features USB ports that allow users to charge their electronic devices such as smartphones, tablets, and cameras, making it a versatile and convenient tool to have on hand.So, when NOCO got in touch to see if we’d like to give their NOCO Boost XL GB50 portable jump starter a test we were all for it. This thing promises a bunch — it can keep your gadgets charged and it can jump start your wheels. Portable battery chargers are no innovation these days, but with the added features on offer here we were excited to give it a whirl. The GB50 is designed to jump start 12-volt lead-acid batteries down to 2-volts. If your battery is below 2-volts, the Boost LED will be "Off". This is an indication that the GB50 can not detect a battery. If you need to jump start a battery below 2-volts there is a Manual Override feature, which allows you to force "On" the jump start function.
