Purchased for a pre-planned power-cut. Worked all day off an old 12v car battery. More than sufficient for the hub, several device chargers, light, and did not once trigger the over heating fan. Very happy

Good quality

Julian Moy Verified Purchase

I was surprised that Tool Station actually sold this item let a lone had it in stock at our King's Lynn Store for collection.The inverter came with an adapter for the inside of a car/van and also a set of leads with croc. clips to clip straight onto a battery ,which is what we needed. So again surprised that we didn't need to cobble something together for this. The item was so simple to use. Clip onto a charged battery, plug in the garage lighting circuit and switch on. Worked first time. Plus ....as usual at KL...used Click and Collect....took less than 60 secs. to pop in and out of the Store.

Couldn't be quicker

When they work they're fine, but I've had problems. Bought one in Apr 23, it stopped working Aug 23. Returned under warranty and got a replacement. That stopped working May 24. Contacted the maker but no response. Bought a different one from another source. That failed 22 Aug 25 so I bought another Streetwize inverter. That had no output from the start so I returned it.
When these work they're fine but long life doesn't seem to be thing from my experience.

I had the power!

Low price but great performance. Using my caravanbattery, it ran my freezer, central lheating pump, wifi, landline cordless phone, and charged my mobile during a shceduled power outage and the colling fan didn't even need to come on. In fact, it barely got warm at all. I'm usually quite cynical about buying the cheapest and expecting it to work, but this time I was pleasantly surprised. It even came iwth spare fuses! So handy to have in the event of a powercut. I almost felt I was cheating while the power was off. Definitely reccommend you buy this inverter if you need an emergency back-up system in the event of a powercut or need a mains supply when camping etc. .

Great

Exactly what I needed for 5 days without electricity after the storm. Plugged into my EV and ran an extension into the house. I have a wood burner and this provided enough power for a lamp, TV, and internet. Made the experience far more tolerable. Kept us sane.

Easy to use, greatly priced item.

Provides power as described, but at a very loud noise. Generates a lot of heat, and not suited for long drives.

Not great, have had to replace these multiple times to the point the store is directing me to the manufacturer. I have had around 8 of these over the last year over 3 vehicles.
They have been fitted properly and not overworked.
Mainly been used to charge a small cordless drill.
