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: https://en.wikipedia.org/wiki/AC_power_plugs_and_sockets

No. 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). remove viruses. Most of them are too small and will easily pass through the filter. remove substances like salt and magnesium which make the water undrinkable....

Posted from comments as asked. I made a similar mistake at tourist attractions in the past when I forgot mine was in my bag, I had it confiscated from me and it was apparently disposed of. I asked if I could collect it on my way out as it was a family gift but a policy is a policy and there was nothing the staff could do. Edit: I was given the option of ...

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: It ...

The Swissgear TSA lock instruction manual has some guidance on how to reset the red indicator: To reset & hide the red indicator: To return the red color indicator back to its original hidden position, simply push it back into the lock body with a small pin-like device, such as a paper clip. The TSA color indicator is now reset. Tho The OP ...

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 ...

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 with its lower ...

Seriously, this is not a problem. Why ? 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. Concerning gases: If you are not an expert, trying to gas someone does either nothing, alert you immediately or kill you. Mind you, ...

It looks like you won't be allowed in to the park with a knife, and if you try to do so then it may be confiscated by park security and / or you'll be ejected from the park. The list of prohibited items includes "sharp/pointed knives" and "pocket knives" (thanks to Toivo Säwén for pointing out the second one) with the only exceptions ...

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 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): Baggage Rules, 2016 [Notification No. 30/2016 - Customs (N.T.) dated 1.3.2016 as amended by Notification No. 43/2016 - Customs (N.T) dated 31.3.2016 read with corrigendum dated 1....

One of the most important things when buying power strips is safety! I do not see anyone mention this. There are two different safety issues here: Safety of the place, for example overloading. Last thing you want to do is burn the hotel room or so. Make sure it can provide power for more devices and in case of any abnormality it should be equipped with ...

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 ...

The exact regulations will vary from country to country, and their interpretation will vary from person to person, so there's never any guarantee of exactly what to be allowed or will not when it comes to items like Tripods. However speaking from personal experience, I have traveled extensively through at least a dozen different countries on multiple ...

According to a page on the site of (in Dutch) the Royal Dutch Touring Club, you're required to have a warning triangle and a safety vest. While a fire extinguisher and first aid kit are only required for Belgian drivers, they still recommend taking them as well. Another page of theirs (in Dutch) which gives an overview of these rules for various European ...

Yes, bags are sold specifically for this purpose. Features may include: being waterproof having lots of compartments to hold many small bottles (or one compartment with various elastics and such to hold small bottles sort of upright) having at least one compartment to hold tiny little things like bandaids and safety pins having a hook so you can hang it up ...

There are combination French press/coffee mug thingies which are very practical. You only need coarsely ground coffee and *Just Add (Boiling) Water (tm). If you shudder at the thought of pre-ground coffee, you can complement this with a small manual coffee grinder. Bonus points: you can use the same device to make tea as well.

The reason you're finding that they only have them in Europe is gassing is not a common problem in other parts of the world. (Honestly, it's not that common in Europe either). In most dodgy parts of the world, criminals will force their way in, jimmy the locks, or just wait outside your door. Slip something in your drink, or even just blow scopolamine in ...

There are wallet-like holders specifically designed to keep your passport and some other cards (credit card, healthcare card etc) They look like this and can be bought in just about any airport shop I've been to anywhere in the world. This thing is though you can't keep anything on you, everything you're carrying on the plane has to go in those plastic ...

Have you considered an Aeropress? I've been using one for around two years now, and I'm very happy with the quality of the coffee it produces. As far as travel suitability goes, I think it would be a good fit for hotel room brewing, provided you have access to hot water and coffee grounds. It's compact enough to fit in luggage, easy to use and clean, and ...

Yes, Google Latitude! Ok, last year they merged it with google+, so now it's just under locations in that app, but it allows you to share your GPS location with other contacts or friends, on a pinpoint or city-wide location. It used to look like this: source But now, while still similar, is in Google+, and you can activate it as per the following ...

My GPS works fine when I'm off the cell net. Around here that means highways other than the interstates. Every national park I have visited has at best been marginal for cell service, generally no service at all.
