First, if it fits in or as a carry-on and you can manage it, I highly recommend you keep it with you. Many airlines will offer a carry-on limit exemption for medical devices though you may have to contact them prior to note the record. This may even get you early boarding if you don't otherwise qualify.
Second, if you must check it, insure it either with ...
Those circled holes will be for various plug style's grounds, however --
That is not a standard socket.
That is entirely an invention of the Chinese junk sellers.
It has not been approved by any competent testing laboratory, and it definitely never will. This type of socket is simply trying to adapt too many kinds of plugs, at the expense of safety, and ...
All the middle holes are there for accepting various types of ground (earth) pins.
Specifically, the top two holes are there for British plugs (BS 546, BS 1363), while the bottom two are there for Brazilian, Danish and Swiss plugs. As always, Wikipedia has the gory details:
Here's what customs rules in India state (the 'free allowance' referred to is for personal items, and the duty-free allowance of alcohol cigarettes):
One laptop computer (notebook computer) over and above the said free
allowances mentioned above is also allowed duty free if imported by
any passenger of the age of 18 years and above.
So obviously, ...
Physical filters using pores with 0.2 µm (microfiltration) cannot
remove heavy metal contamination (lead, mercury). This is possible with
ion exchangers, distillation and nanofilters (see below).

Towels are 50/50 possible, depening on country and hostel.
More hostels will rent towels, sometimes at a nominal price. One hostel I worked in in Australia used to provide free towels but we discovered we were often paying overtime to our laundry staff because people would use many towels just because they were free! We introduced a $1 fee per towel, ...
I arrived at the kit below by adding gear only as needed. I started with just an iPhone and laptop and only added to that when it was literally impossible to get reliable internet at my accommodations with the gear I already had. I have trial-and-errored through a bunch of other gear that turned out to be unhelpful or not worth the bulk (e.g. higher ...
Such a list would not be meaningful. All airlines have wide rules to prohibit "tampering" with seats, with Knee Defenders or otherwise; you can improvise one with a well-sized bottle, after all. Those that point out the Knee Defender as banned are only making it explicit that this specific device is not allowed.
More to the point, if the passenger unable ...
To add to Thorsten's excellent and quite accurate answer:
No, it takes quite a lot more than that to create perfectly safe water. For example, here's my Indian water purification system. I know it's not feasible for travellers, but I'm including it to illustrate just how much is actually needed to get really pure water:
Some things to note about it:
Yes, there's an app exactly for what you're looking for, and it's called Glympse.
You can choose to share your location, set a timer on how long that location will be shared, and send the details (it's just a link) to any of your contacts via text message, Twitter, email, a bunch of other messaging apps etc.
What I like about this is that you can limit ...
The rules about knives through airport security vary from country to country. Generally, they all include "a blade over x cm in length". While x may vary, your blade looks to be at most 4 cm or 1.5". So if the rule is a blade over 5cm/2" is not allowed, you'll be fine. I think that is the rule most places, and there was talk of raising it to 7cm in the US ...
Get a European USB Charger
I would buy a USB charger with a European plug (image courtesy of aliexpress):
Travel Convenient EU Plug Wall USB Charger Adapter For Samsung Galaxy S5 S4 S3 Note 3 by Ali Express, fair use
It beats the weight of your US charger plus a plug adapter, it's cheap a as dirt (2-something bucks on eBay), it can be used for all your ...
It would appear not, but there's nothing stopping us from creating one. People can edit the answer as we find more.

When power outlets were first installed on airliners, they used a special adapter called EmPower, which looked like this:
The airlines obviously thought that frequent flyers would be happy to buy a new kind of adapter for all their gizmos. This turned out not to be entirely true... nobody wanted to buy these new stupid adapters, and the airlines eventually ...
One of the simplest, cleanest and cheapest solutions that I've seen is a couple I met who were travelling around South America. They'd back up onto a second SD card as well. When a card was full, they'd simply put it in an envelope and mail it home. Very cheap and very easy, and pretty reliable. Send it registered mail if you don't trust it.
Once their ...
According to the producer of the backpacks:
“SL“ stands for Slim Line. The entire pack, including the carrying
system, is designed with a woman’s physique in mind, but can also be
used by anyone with a smaller torso and frame.
Features of the SL system:
A slightly shorter back length (to accommodate a shorter torso). The SL back system ...
Seriously, this is not a problem.
The brother of my former girlfriend was an anesthesiologist. I
was interested if it is possible to have something for sleeping
(I am seasick) and I got a longer speech about anesthetics.
If you are not an expert, trying to gas someone does either nothing,
alert you immediately or kill you.
Mind you, ...
things I do occasionally with my towel while traveling:
fold it to a pillow at night, or cover any (stained) pillows i encounter in cheap hostels/motels
place wet clothes on one half, then wrap the other half over it and sleep on it, and the clothes should be dry next morning
as a beach towel
group loose or dirty/wet items together in your backpack
fold it ...
I use Lifeventure Hydrofibre Trek towel and must say that it is amazing. That's a subjective description and now for the objective one:
First my tests at home
I tried putting it in a pint glass (0.5 liter) full of water and it absorbed about 85% if not more of it. It did drip though but let's be honest, you'll never gonna be that wet to start with.
It's very hard to make a universal socket that's compliant with all the safety standards that would apply. Eg in the UK BS 1363 sockets must have shutters over the L and N holes and plugs must be fused.
The simple answer, if you are travelling to many countries, is often to take your domestic power strip but change the plug on it to a IEC 60320 inlet. This ...
There are various way to do this, none of which are risk-free. Any damage to you, your personal property, nature, the Universe is entirely your fault.
You Cannot Fully Charge Your Device
The bottom line however is that you should avoid fully-charging the battery. Instead you should aim for a short charge, giving you enough juice to ...
I think they're more common in countries with poor safety regulation of electric devices.
This adaptor strip/board was at my hostel in Tbilisi, Georgia at the time the question was first asked:
It seems to be made by a company called "Veto" with model number 606F, but I couldn't find anything by Googling.
And a few days ago I found a "bin" full of these ...
The TSA actually has a section devoted to this on their website:
You may bring skydiving rigs with and without Automatic Activation
Devices (AAD) as carry-on or checked luggage.
Typically, a rig will move through the checked luggage or carry-on
security screening process without needing physical inspection.
However, TSA security officers have ...
Almost always, you bring your own, however...
Hostel sites like Hostelbookers often indicate whether or not items like towels are available for rent, or provided.
Some I've seen will sell toothpaste and deodorant and the like.
Personally, I bring a towel and toiletries, and almost always I've needed them. It's generally a surprise when I don't.
I quite often fly with a CPAP machine in my checked luggage (and less often as carry-on), and I've never had a problem with it. I will be doing so later today, and don't anticipate any problems (unless the maple syrup in my luggage leaks everywhere, in which case I'm stuffed).
Johns-305's answer is much the best option (+1 from me); when I have to fly with ...
It seems the rules were revised amended and corrected to come into effect from 1st April 2016 and the following combines these changes (but may have been changed since):

Disadvantages of cell phone GPS services:
They rely heavily on cell phone and wifi access points for the initial fix.
They are only as good as the maps on them; see for instance google maps vs. apple maps.
It is not trivial to get other information (such as elevation) from these applications.
They are primarily designed for urban areas; they are very easily ...
