Laser Power Bank

I bought a 5000 ma laser powerbank from Big W a few months ago (didn't keep docket) I use it to keep phone alive during the night listening to far away radio stations. It worked o k for a while and then started to run out quick and be very cantankerous taking charge. (from Apple chargers), sometimes not displaying more than 99 and then sometimes going full 100. now it is zero and will not take charge at all.
Can not at all recommend that brand. Bought it on special for 20 bucks and have had 50 bucks worth of pain. Last time I was in Big W in our local store there were not many Lasers on the shelf and not one of the size I got. Just proves that you get what you pay for. Pay peanuts and no monkeys!!!

I bought a new Laser power bank from
Big W last week and plugged in my phone and it instantly froze and went black!
I lost 3 years of work and notes and data. Everything is gone and I am not happy.
I paid about $1100.00 for my phone at jbhifi. Its now a useless brick. Thanks Laser.
I contacted Laser about it to warn others. The Laser service guy was so arogant!
He said it could not be a power surge and it was a coincidence!
Well the coincidence cost me $1100.00.
Then why does Laser print on the bottom front cover "protection from surges".
