## Description

From the manufacturer GBX155 GBX45 GBX55 GBX75

Review: POWERFUL IS AN UNDERSTATEMENT - GOODNESS ME, this thing packs a huge punch. Started my 4x4 that had a completely kaput battery in a matter of 2 seconds. Not cheap but its an awesome bit of kit
Review: If you get a good one it’s the best out there, keep your warranty handy just in case. - Good strong units, Will jump start anything with high power, recharges fast with the pd65w charger and well built. Only downside is we have had a few fail ( we use them quite often and have about 6 ) sadly 3 have had to be returned due to charging faults but hopefully this will be resolved by the company by better quality charging ports or what ever is responsible for them going wrong. When working they’re great.

## 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.
