## Questions & Answers

**Q: Hi do you do a case with the noco gbx155**
A: I bought the GBC015 case, it says that it will not fit,but I took a chance as the dimensions were the same. It is a little tight  but I think it fits well  and protects it and makes it easy to carry.

**Q: while on charge do you turn the pack on**
A: Once you plug your unit in to recharge, you will see the charge indicator start to pulse from red to green , once you have a steady green then it is fully charged .
You don’t have to switch it on when charging as the unit is intelligent and will automatically select the charge sequence

**Q: What is the correct usb plug to use when charging the GXB 155**
A: The one that was included with the booster, it plugs into a standard USB. it will plug into  a fast charger as well using included cable.

**Q: How long can I power my 60w usb-c laptop  from this device, assuming fully charged to start with**
A: Hi - I'm guessing here but the GBX155 has built-in a 99Wh Li-Ion Battery, so if a laptop is drawing 60watts (60Wh) it would power for 1hr 29mins on a good day.  I would suggest further research as this is a very simple guess - thats working on the psu is 60 watts and not what the laptop actually takes to run (mostly likely less than 60watts to power and charge at the same time!)  - But the Noco range seem about the best out there for battery boosters for cars.
