Only takes 2 batteries at the time, the other ones are just blinking but don't do anything!

Quick charge. No USB port

It can only charge 2 batteries simultaneously. Its essential two dual chargers in one. The left 2 slots are bank 1 and the right 2 slots are bank 2. Bank 1 and 2 can each charge 1 battery at a time. When 1 battery finishes the other in that bank starts. No issues though.

Ordered. Found out that it doesn't work with 4 batteries. So completely pointless. Asked to cancel and issue refund as delivery wasn't till 14days later. To then get a double charger delivered and not cancelled and no refund.Don't buy. Can get a Real makita one that charges for 4 for same price

Finally I can charge multiple batteries with one charger.

Only charges two batteries at a time expensive for what it does should have got two twin chargers instead
