NOCO Boost Plus GB40 Review
As a seasoned mariner, I've had my fair share of dealing with dead batteries on my boat. That's why I was excited to test out the NOCO Boost Plus GB40, a high-capacity portable battery pack designed to provide reliable power when you need it most. In this review, I'll put the GB40 through its paces and share my honest assessment of its performance, features, and value.
Design and Build Quality
The NOCO Boost Plus GB40 has a rugged, compact design that's perfect for stashing in a tackle box or on a nearby shelf. The battery pack measures 9 x 6.1 x 1.5 inches (23 x 15.5 x 3.8 cm) and weighs just over 2 pounds (0.9 kg), making it easy to carry around the boat without taking up too much space.
The GB40's ruggedized casing is made from durable plastic that can withstand rough handling, and its reinforced battery contacts ensure secure connections every time. I was impressed with the build quality of this unit – it feels solid and well-made, which is essential for a device that'll be exposed to harsh marine environments.
Performance
The NOCO Boost Plus GB40 packs a punch, delivering up to 7 hours of runtime at moderate power draw. I tested the battery with various devices, including smartphones, tablets, and portable lights, and it consistently performed well, even in cold temperatures.
- High-capacity design: 42Ah (ampere-hours) lithium-ion battery pack
- Fast charging: supports up to 40W USB-C PD, 12V DC input, and 5V USB output
- Multiple output ports: 2x USB-A, 1x USB-C PD, 1x 12V DC output, and 1x wireless charging pad
- Integrated boost mode: charges dead batteries or jump-starts engines up to 20Ah capacity

I was impressed with the GB40's ability to handle multiple devices at once – it didn't struggle even when connected to a tablet, smartphone, and portable light simultaneously. The boost mode worked as advertised, jump-starting my trusty outboard engine in under 10 seconds.
