"This solid and reliable piece of kit keeps my Fireblade battery at full charge while its not being used during the cold weather.[winter] I plug my Optimate Trickle Charger into it for 2x 2Hours per week on the inverter function of this handy garage accessory. My bike has an alarm that draws power from the bikes battery so needs a good reliable charge. I can also power my garage lights for when i'm tinkering with said bike etc. It will also spark-up my 3 x 36 Watt tubes for upto an hours lightihg but drains the battery too quickly for any longer. Many other features on this portable powerpack to power many things plus a compressor for my car and bikes tyres although i do use a seperate tyre pressure gauge for accuracy. Had it 18 months now and if kept charged i have not noticed any power drop or loss."
