LVYUAN 2500W Voltage Transformer Power Converter Step Up 110V to 220V, Step Down 220V to 110V, 110/120 Volt - 220/240 Volt

Works as advertised and was able to be setup and used by someone who is not technically inclined without issues or even reading the instructions.

I bought to use with a small appliance from the UK that I loved and could not find in the USA. It doesn't take up much space and is easy to use. I'm very pleased with it.

good

I used it on my oversea bought rice cooker. The transformer did its job. I’m very happy with the product.

It doesn’t work anymore, my item connected to it just shuts off now then turns on again a few min after then shuts off again. I do not recommend this one, sorry.

Good

Works perfect, well designed and exactly what I need

TL:DR; If it lasts (seems great), this is an amazing deal!! Beware the weight. Might not really be full 800W.Highly recommended.First off, this thing is a heavy beast. Super solid. It says it's under 8lbs, but it feels like 20, lol. I wouldn't put it in a suitcase with anything breakable. But if it was anything other than super solid and heavy, it would be very suspicious.For my case, I've got some really cool devices that run off of 220V - desoldering irons, scopes, etc. that won't work at 110 and must have the correct EU frequency and voltage.This works perfectly. Nothing to it.I also have some musical gear -a 100W guitar amp that can take 220V input and a musician friend recommended that setting for better sound. I've had no way to test it until now and I have to say it works very well. As bad as power can be in venues, it's probably a good idea to use something like this although I'd worry (just a little) that bad input power could hurt it.Another reviewer mentioned that it would be better if it had a fan. I hadn't even thought of that and I ran this for hours every day for over a week. I guess in some cases (higher wattage usage) it would be important for that, but not for my uses. And I'm glad it doesn't have a potentially annoying fan coming on when using a scope on audio gear. And at this price, getting a small fan to use with it would still be a great deal.A big bonus is the opposite use - to be able to power US 110V musical gear in the EU. A touring band could run all their gear from home through this. and then have it for the hotel room to plug in all your electronics and stuff.For normal casual travelling though, the weight is a factor.And finally, I have searched a long time for a good high wattage voltage transformer at a reasonable price. One that I have is step down only 220V-110V and it cost over $300 (and weighs almost as much) and I have another that is up/down but only up to 150W and it was $250.To me, this is a FANTASTIC price. Shocking, really. As I write this it's $75.99 with a 15% discount which is some sort of math that leads to less than $75.99 - it would be worth it to me at double that price.And as a warning, it's been my experience with cheaper gear like this that while it can be reliable, it might not be spec'd out the same way US made/approved gear would be, so I would take the max number (800W) with a grain or two of salt. Maybe 600W. I don't have anything to back that up on this particular unit, I didn't take it apart and test it, it's just based on experience. Another thing to be aware of is that the grounding path may not be done the same way that it is done here. If that's a concern, be sure to have your device (this or any other) checked by someone qualified. My test on this showed proper grounding continuity.Fantastic unit. Highly recommended.
