BESTEK Voltage Converter 110V to 230V Step Up Transformer with 4-Port USB Charging US/EU/AU Adapter UK to US Travel Charger, White-Blue

Buy it really whether you are going to Spain / Portugal/ Romania USA / Canada, well you will need two adaptor plugs as well one for the USA and one for Europe. But this will keep you and your devices safe and with 200w power, and no surges one set up, you have four USBs and two Sockets for Plugs. This also comes in very handy in hotels etc for adding the extra socket, and USB ports, mine has been used in all the above countries, I have had it for about five years now and it is still as good as the day I bought it a very good product.

A bit of last minute research on travel plug adapters for visiting Tokyo, Japan, revealed that not only an adapter was required but a step-up transformer! Japan’s domestic electricity runs on 110v as opposed to the UK 230/250v. Some modern devices will work ok (iPhone will charge for example), but my older laptop specifically mentions incompatibility. This transformer is exactly what I needed. It’s relatively compact and comes in a very smart carry case. It feels solid and although I have only used it for the week of this business trip to Tokyo, it’s perfomed beautifully. One additional nice touch is the on/off switch on the unit itself. This allows you to leave it plugged into the wall socket and simply switch on at the unit. Hey we’ve all stayed in hotels where the wall socket is difficult to get to, usually right down behind the dressing table! In sum, it does what it is designed to do and fits the bill perfectly.

Looked nice. Came highly recommended, with lost of 5 stars revues. Purchased it because we have recently moved to Northern America from Europe, and needed to convert the local voltage (110V) to European (220V) to charge various devices (in under 3 days at a time).Made this buzzing noise from the start when in operation, but I understand from the other reviews that it's what it does. Worked for about 2 months, on and off (in that we did not leave it on all the time, only switched it when needed), and then one day it just died.Would not buy again, and with this experience, will not buy anything made by Bestek again.

Adapter arrived quickly and seems to be well made, although as expected it is not light. The unit has had limited use so far, but does appear to work well enough. My one criticism of it is that there is nowhere to plug in a two-pin razor/toothbrush plug. Most travel adapters these days are able to take standard three-pin plugs or two pin ones. This seems to be a real oversight in an otherwise well designed and mande unit.

I do a lot of trips over to the US and this little travel adaptor has changed the game.Because the voltage of a UK charger doesn't work well (if at all) on a plane, I've always struggled to use things consistently without bringing a portable charger, but with this little gadget it's so much easier! I can now plug my laptop into the device, and then the device into the plane!The device ups the voltage inside easily and it's very small considering what it does!Really happy - thank you Bestek!

This is a nice unit (switch mode power supply) which gives you 2 UK 13A type sockets for lower power type devices. It offers 200W of output which means a laptop and a bunch of chargers phones etc. It has overload protection but does not state if it has AC smoothing and spike protection which would have been nice. This unit will not work with anything that creates direct heat (hairdryer, iron, or heated tongs etc) as most of these exceed 1KW. I would have given this 5 stars but for. The cooling fan can be annoyingly loud at night if you are recharging, it has a buzzing sound which I couldn’t sleep with it on. The unit and the AC cable are heavy in a good robust way but, not in a travel lite way. It comes with all the a travel bag which is handy but with the unit, mains cord and travel adapters it is bulky for the airline road warrior. The ability to just plug in and play is handy and there are 4 USB type A ports to if your laptop uses.USB-C to charge Apple & Dell newer models, then you can leave the laptop charger at home and just bring a USB type A to type C cord. In fairness, the bulk is not anything other than UK electric regulations and safety. So Bestek could have made it smaller but it would not conform and thus be illegal.

Bought this as we were going to a country that had 110v as standard everywhere. Well worth buying this if you have to charge lots of devices while away as it has 4 USB slots and 2 UK-style plus to plug more stuff in. Works really well and the kit comes with some standard non-UK plugs that can be used in USA, far-east, etc..

All well. Thank you!
