Question: Is adapter approved for charging laptop and cell phone ... many have warning regarding electronic devices
Document: Purchased this adpater for a business trip to Europe. The device worked the first night to charge my laptop and cell phone. The second day it was completely dead! Tried multiple devices, cables, outlets and even gave it to a coworker to try with no luck. Don't know what happened, but it's not a power converter, just a plug adapter so even if there was some sort of power surge I don't know why it would matter. Grateful none of my electronic items were damaged at least.
I love this adapter, it is a significant upgrade over my previous world travel adapter as it includes 2 USB charging ports. This means I can leave 2 wall wart AC plugs at home and charge 3 devices at once with just this adapter. As an example: I plug my laptop into the main outlet int his adapter, my phone into one USB and my tablet into the other. I can't recommend this adapter enough, as it reduces what I need to bring when traveling.
Adapter is nice because you can charge a laptop and plug in 2 USB devices at the same time. Many will be an either/or scenario. Constrution is a little flimsy compared with some, but seemed to hold up okay so far.
Worked well on a recent trip to Germany/Austria. I would not recommend carrying this bulky/heavy adapter unless you need USB power. The 2 USB ports were very handy for charging phone/GPS; and my laptop charger had no problems using the unaltered (230V) voltage on the 5-15 receptacle. Four separate adapter prongs slide out separately to handle pretty much any standard input type around the world.
It is excellent for travelers and allows charging many devices without any problem. The USB ports looks loose littile bit.
But if my 13 year old son can figure it out and use it with no issues, then you can too!I wouldn't try to use this anywhere else, and I wouldn't plug anything into it besides low wattage devices like cell phones or tablets or laptop chargers that have their own power converters. I wouldn't use a hair dryer or a coffee machine with this. You need a step down power converter for those kinds of appliances.
I used this in Germany and it worked perfectly. Some people complain it is a little bulky. It is bulky because it handles multiple countries, is a surge protector, handles multiple voltages, has a built in fuse, and has 2 usb ports. I used it to charge my laptop, tablet, and cell phone simultaneously with no problems. This one shouldn't fry your valuable electronics like some super cheap adapters might.
I can only comment on how well this adapter works for outlets in Australia, and that is to say, not at all. When plugging it into a wall outlet, the connection (on many outlets that I've tried) is not very secure already. Then, adding a plug such as that of laptop, the connection won't even hold.
and immediately you have a plug adapter (even for US three prong grounded plugs) AND two handy USB 5 volt, 1 amp each, outlets for your cell phone, Kindle, iPad, etc. (NOTE: this adapter is not for appliances that require a grounded outlet - it does accept grounded appliance plugs, but it is not grounded when you plug it in.
I am a world traveler, and I have to say that this adapter does not leave my side. Unforunately, it does not have a South African adapter in it, but serves a great purchase for other countries in Africa I go to often. I though I would have an issue with charging two cell phones at once, but found that is worked well as long as you use the right changing cables for it. Yes, USB cables are different.
Answer: Hi Roge,I used it to charge my Macbook and 2 mobile phones at the same time and everything fine and still working :)
