If you plan to travel to another country, then don’t forget about electrical outlet adapters. Thankfully, there are adapters that do the job regardless of whether you travel to the UK (3 prong) or continental Europe (2 prong).
Now these outlet, or socket, adapters are NOT the same as voltage converters. In the USA, electrical devices us the 110 voltage current. But for most of the world, 240 voltage is used. Many electronics come with a A/C adapter that will handle both 110 or 240 volts. You can verify this by locking at the technical specs on the adapter. It should say 110∼240v. In fact, nearly all A/C adapters for cell phones, laptops, tablets, and such can handle both currents.
If your A/C adapter or electrical device ONLY says 110v, then using that device on a 240 outlet will cause it to overheat and die!
The outlet adapters below merely allow a USA prong to plug into a UK or Europe outlet. It also works the other way around for those coming from the UK to USA.
The M8+ can handle pretty much any country that you travel to
