Absolutely brilliant, well worth the money, purchased week ago for Straddie, 4 days over here and hasn’t missed a beat... my only criticism would be the buttons on the lcd screen, they are a little unresponsive.. even holding buttons for 1 second as recommended.... they could be a bit better, but this is my only gripe

I am so excited that this smart battery box is every thing it promised. I had it in stalled today and it raised a lot of interest with the mechanic and the auto electrician. Thanks Tentworld

Picked one of these up from the new Woolloongabba store in Brisbane. Staff couldn't be more helpful. Was the best price around even compared to online. They even gave me a discount on a few other little things i bought at the same time. Will likely be back soon to get my fridge once i decide on which one. Thanks!

I bought one of these boxes about 6 months ago from Aussie disposals and it did not include 240v mains charger. The shop of purchase will not chase on up for me and I find it really frustrating cause I can only charge via clamps on a battery charger. It is therefore not getting used to full potential. Can I please buy one seperately then I would rate the item 5/5

Tentworld Tentworld ResponseIt does seem that really your rating of 2 stars is more to do with the service you've received from Aussie Disposals than for the battery box, or us Tentworld. Sorry to hear of your troubles and frustrations. Your battery box should include the 240v adapter, and Aussies should sort this out for you by taking one from another unit and sorting this out internally with Engel. At this point it could be easier to ask for a refund to allow you to buy another unit from us ! I hope you are able to use your unit to its full potential soon. Kind Regards & Happy Camping ~ Tentworld team.
