Review: Excellent customer service addressed the issue! - I have raised my rating to 5 stars, & am going to leave previous review below on site in case anyone else has similar issue. BE ASSURED, Bestek will take care of you promptly if an issue arises! I heard from their customer service right after I left the previous review. However, I did not have time before I left to deal with it, so took the unit & hoped for the best. The unit worked just fine as converter and charger in the UK during my travels, albeit the high-pitched whine. I used it for elec toothbrush, iPad, & iPhone. It also got rather warm, even with the interior fan running. I couldn’t charge anything at night, or during the day if other people were around, due to the whine. If the whine started, I would have to unplug the unit from wall to make it stop. When I plugged it back in, sometimes it would be a little time before whine began again, sometimes it would start immediately. When I returned to U.S., I contacted Bestek to let them know I was back, and they sent me a new unit. The new one works perfectly. I can charge multiple items at once, no high-pitch whine, no matter how long everything’s plugged in—in fact, can BARELY hear interior fan, with my head right on top of it—and unit BARELY gets warm. The little fan inside runs even more quietly than the first unit’s. I’m excited to go back to Europe and use it. If anything changes with performance , I’ll be sure to note it. BESTEK did not want the first unit back, so I’m going to take it apart and try figure out why the whine occurs, if anyone’s interested. I’ll be letting BESTEK know what I find. Review of first unit: I wanted to test this before I head to the UK, so I plugged my electric toothbrush into it, used the U.S. adapter, and plugged it into the wall. After it warmed up a bit, the fan came on, which was fine, the little whirring noise isn't bad...like a tiny fan...however, LATER, it turned into a very high-pitched whine/whistle. The unit didn't feel any warmer than when it sounded like a fan, so I don't know why the change. Neither sounds are super loud, but I could hear the whine walking into the bedroom. So I turned unit OFF when I went to bed, and left it plugged in, thinking that OFF should stop the whine shortly. I made a pillow "wall" between me and the nightstand it was sitting on, which was enough obstruction so I couldn't hear the whine, and fell asleep. I woke up HOURS later, leaned over my pillow wall...and it was STILL WHINING! So I unplugged it, and almost immediately it stopped. BTW, my elec toothbrush got charged, so the elec current seems to be working fine. Only a 3 for now, as I hope I'll be able to plug it in away from my head when I'm in UK! More later!
Review: Great product - We took this converter to Europe in May for a stay in the UK, and it worked perfectly for us. My husband uses a bipap machine at night, which meant we needed a dependable converter. This one was perfect. It's small enough to sit comfortably on a small bedside table, and the cord of the converter is long enough not to have to worry with an extension cord. The two extra plugs were very handy for charging my tablet and phone. One of the best features is that three things can be plugged in at once, with no need to unplug one device while using another. Also, the converter and its attachments (which all live in a handy drawstring bag) are lightweight enough not to add to packing headaches on flights. I'm very happy with this device.

## Questions & Answers

**Q: Does this work in israel?  i think it needs an h adapter.  will it work with a curling iron?**
A: A curling iron would be too much of a load for it.

**Q: can you use it with a small appliance like electric toothbrush charger?**
A: Small electronics like an alarm clock or phone charging, but it typically can’t handle the load of appliances.  I’ve used mine to charge my electric razor though so a toothbrush should be okay.

**Q: Is it possible to replace the adapter part?**
A: We have the adapter, ASIN: B07MVG4J69. But currently it is out of stock, please stay tuned, or choose other adapters instead.

**Q: can i plug printer in it ? thanks !**
A: Check wattage on printer. The power adapter will always convert 220 volts down to 110 volts hoppy travels

### ⭐⭐⭐⭐⭐ Lifesaver overseas to Asia
*by K***N on July 7, 2024*

We got two of these based on reviews and online articles about folks traveling to Korea and Japan. Those readings could not be more right. These things saved our bacon in terms of providing 1) the right adapter/plug compatibility and 2) enough plugs and ports to support all our devices (family of four, with multiple devices per person). Nothing short of great! I think the total charging capacity of this strip is not super high, so charging high powered devices may cause some problems. We came close and the unit started buzzing pretty loud, so we used a different plug for a few devices and that fixed the problem.
