How many times can the GB40 charge my device?

The built-in USB 2.1A output port can charge all your USB devices like smartphones, GoPro cameras, wireless headphones, and more. For example, the battery capacity inside your iPhone is measured in milliamps or mAh – measuring how long a device lasts. Devices that are frequently used, such as phones and cameras, often require more power to last all day than the device's battery is designed for. The Boost battery pack increases the life and run time of your device. Also, turning on your device from an external battery pack will reduce the charging cycle of the internal battery, extending battery life.

How to use Noco gb40 genius boost jump starter?

You may be concerned when you connect your Noco gb40 boost jump starter to a dead battery and start to hear clicking noises from the charger. The clicking noise is the sound of a relay starting and stopping the charging process and is a normal operational sound when the unit goes into charge mode.
However, if the clicking sound from the charger becomes regular and more rapid then it usually indicates that the battery you want to charge is in a poor condition may be due to its age, or is completely dead so it may not be possible to jump start it.
As the Noco GB40 attempts to charge a battery that needs replacement the voltage will increase far quicker than a healthy battery. This quick increase in voltage will lead to the charger switching off its charging mode. However as the current will then drop quickly then the unit will then start its charging mode again so you will hear a clicking sound. The constant starting and stopping of the charging mode result in the clicking sounds.

Conclusion

Noco Genius Boost Plus GB40 is a lithium jump starter worth having. It is a compact but so powerful device. Used as a portable mini jump starter it can solve your problems related to a drained 12V car battery. Also as a multi-function device it can be used as a power bank. GB40 NOCO recharges your smartphone up to four times so it is great to purchase it when you don’t have the power source nearby.
This advanced technology based on the lithium-ion battery is completely safe to use. No matter whether you are professional or not, with this device you will be able to solve the most common battery problems.
Strength in strength, this lithium starter battery beats traditional lead-acid batteries in size and weight. It's 10X smaller and 8X lighter, and its design makes it more compact and portable than ever before. Conveniently stored in the glove box, center console, trunk, or instrument panel.
In our Noco GB40 review we have identified some things that we don’t really like, such as the design of the device itself, although it is heavy and sturdy. We have found the user manual a bit difficult to read, and it sure would have been nice if it came with some sort of standalone box. It comes without a wall outlet AC charger and any other equipment, so we find this as something that probably should have been included.
There are some things we don’t like very much such as the design of a device itself although it is heavy and durable. We have found the user manual a bit hard to read and for sure it would be great if it came with some self-contained box. It comes without an AC wall socket charger and any other equipment so we find this as something that for sure should have been included.
But we believe that these drawbacks are not strong enough to deny all the great things of this powerful device can do and it is just up to you and your needs. In our opinion it works as promised. It is very important to use it as the manufacturer recommends and we see no reason why this device shouldn’t be in every household.
Thank you for reading the Noco Genius Boost review.
