Rugged Rukus Portable Solar Wireless Sound System

I have owned this rugged, splash-proof speaker for about six months. I purchased it for week-long bicycle tours and camping. It is a combination of solar charger, battery and speakers in one unit. I charge my phone and i-pod when off the grid. The speaker has blue-tooth and auxiliary (wired) input and indicator lights for battery status, etc. I use the two loops to strap the speaker to my bike bag for listening on the road. It sounds great for its size. It even fits in a large pocket of cargo pants.

Diablotek 8800mAh Portable USB Battery

[This is out of stock on Amazon. I can't find another source for this particular battery. If you know where to get them, please post in the comments. -- Mark]

I’ve been a road warrior for years now, and have gone through over a dozen different Portable USB batteries – they have all either broken (Looking at you, fancy LiPoly chargers!), I’ve lost them, or I outgrew their capacity.

Capacity is the name of the game with this little device! While it is heavy, weighing in at 247 grams (Slightly over a half pound), it packs in every feature that a road warrior would need:

* 8800mAH capacity
* 2 standard USB ports, one outputting at 5V-2A
* Charges via a standard micro-USB cable
* Simple On/Off
* A ring of LEDs around the power button show capacity remaining (Both charging and discharging)
* Comes with a handful of different adapters, though they aren’t needed

I picked it up at a local Microcenter for less than $20, thinking it would be trash — but it’s survived dozens of drops, hundreds of charge/discharge cycles, water, mud and more than enough to have me come to depend on this little guy!

The best part is the 5V – 2Amp output – this allows most devices to enter a fast charge state, which is noticeably quicker than with a standard socket.

On a recent 6-hour flight, I kept both my Android phone and my power hungry Nexus 7 plugged into it. I played games, listened to music, or watched movies the entire time on the Nexus and when we landed both devices were at 100% AND the little USB battery was still at 75%.

In fact, I have yet to drain it beyond 50%, and that includes a 12-hour day of Geocaching with my phone’s GPS on and the screen fully awake.

It also holds a charge for a long long time — I’ve left it alone for 6 months, only to come back and see it’s still at almost a full charge.

If I had an gripe with it at all, it’s that it lacks an attachment point, which is corrected with some epoxy and a trip to the hardware store.

Couchsurfing * Airbnb

I travel a lot. I hope to never book a hotel room again. I stay in people’s homes, arranged either by couchsurfing or Airbnb.

While I was traveling through Europe as a student I got tired of staying with other American travelers in hostels. I was looking for a more authentic and local experience so I began to stay in homes through Couchsurf.com. Over the years I’ve stayed in about 25 homes. Once you sign up you can search for locations and hosts with similar philosophy, interests, and traveling tendencies. There is no payment for sleeping on whatever couch/bed/futon is provided. To show my gratitude I make it a rule to cook a meal for my hosts. I’ve also reciprocated the generosity by hosting couchsurfers in my homes. CS runs on trust, interests and positive reviews. Since there is no payment, the main reason to join is to meet like-minded people who have stories and camaraderie to share. As long as you have a detailed profile, you will attract and find people with similar interests. Being a female traveler has never been an issue since I normally travel with a friend, or I choose to stay with primarily female hosts. I have met some of my best travel companions and friends through CS. You can find couchsurfing all over the world now.

Now that I am working I can also use Airbnb. Airbnb offers an elegant interface and large database of ordinary to extraordinary places to stay all around the world, at a reasonable price. The service they offer is the curation of unique places, as well as increased security. Part of why some people will stay in an Airbnb and not a couch on CS is because Airbnb treats security as its primary financial and legal liability. Airbnb offers a 24-hour hotline, secure payment platform, identity verification, verified photographers and profile reviews. They also show whether you have mutual friends with the host, which makes me more inclined to stay with them. I’ve discovered some unbelievably beautiful and unique places that I otherwise would never have had access to at a price lower than a conventional hotel, almost by two or three fold ($50 vs. $100-150).

Both CouchSurfing and Airbnb offer “local experiences” and a more affordable way to travel. However, CS requires more of a commitment to engage with your host (share stories, eat a meal together) in exchange for free board vs. Airbnb, which requires payment yet is more luxurious and less personal. Think of it as the difference between getting a ride in a taxi (Airbnb), vs. from a rideshare (Couchsurf). In the cab you sit in the back and you don’t need to talk to the driver if you don’t want to, while the rideshare is more intimate so you sit up front and chat.

When deciding which service I want to use, I always ask myself: Do I want surprise or security? CS always surprises me with interesting people and stories, while Airbnb offers local luxury at an affordable price.

Presto Power Pop Microwave Corn Popper

I do love popcorn, but usually don’t like to pop commercial microwave bags in the office. Although their contents are delicious when popped, commercial microwave bags release a cloud of buttery esters into the local environment for all to smell. They have a TON of added fat and salt, and one has no control over the contents.

There’s also a great deal of debate over the safety and stability of polyunsaturated fats in high-heat cooking, and corn popping is a very high-heat process.

Hot-air poppers aren’t suitable for an office environment, and anyway I haven’t found one that doesn’t eventually make the popped corn taste like it came out of a hair dryer.

I have used the Presto Power Pop corn popper for at least a decade, and found it to be an excellent solution to light snacking in the office. It doesn’t smell strongly of anything but the corn, and that can be controlled by keeping the lid on until I’m back at my cube. I can control the amount of salt or oil I use, if any. It acts as a serving bowl for the popcorn, and is easy to keep clean once emptied. It does an excellent job of popping most of the corn, even in lower-power microwaves. It typically will pop a batch in under two minutes, not three to four like commercial bags. (Which makes one wonder how much of the mass inside commercial bags is popcorn, and how much is just colored fat.)

Its construction is fairly simple: a bowl, a detachable base with a metal reflector disc inside it, and a paper/foil heater cup. The cups are replaceable, but last a long time for me. I’m just finishing my first 8-pack of them after 10+ years. Granted, using oil in the popper will make them deteriorate more quickly. Also, as microwaves have increased in power over the years, I notice the cups burn more quickly. Replacements are available in many big box stores and at Amazon.

About Corn Popping:

Use fresh popcorn, and keep it hydrated so it pops well. Every few weeks, if your bag of popcorn lasts that long, open the bag and sprinkle maybe a half teaspoon of water into it. Close the bag, turn/roll it over a few times to distribute the water, and then let it sit. You don’t want a lot of water: just enough to keep the corn from drying out, not enough to make it germinate.

The best salt to use is superfine salt, like the movie theaters use. There’s something about that initial super-salty hit from extra-fine salt, that quickly fades into the mellow sweetness of popped corn. That salt/sweet balancing act is a visceral trigger that has kept us coming back for more for centuries.

Don’t get the popcorn salt with yellow coloring, it’s just dye. Easiest and cheapest is to make your own fine salt in a coffee or spice grinder.

Salt doesn’t often stick well without a little oil. Very, very little oil is actually needed. So I made a recipe:

Popcorn Salt/Oil Mix

~1 Tbsp. Table Salt
~1 tsp. Oil (Coconut oil preferred, it’s most stable long-term and at high heat)
Coffee/Spice Grinder

Put a few teaspoons of regular salt into the coffee grinder. Grind it for a few seconds until it is a fine powder. Repeat until you have a tablespoon or so. In a very small container (1 oz.), put the salt and about a teaspoon of oil on top. Let it soak in. If it’s coconut oil, it’s OK if it’s solid; it will soak in.

What you’re looking for is a dry crumble of salt/oil. Use ¼ teaspoon for a batch of popcorn. Just place it on top of the corn; the popping action will distribute it fairly well.

[The Nordic Ware Microwave Corn Popper, which we reviewed in 2008, gets equally high ratings on Amazon. It is less expensive than the Presto Pop, and doesn't require replacement cups like the Presto Pop, but other online reviewers complain that the Nordic leaves a lot of unpopped kernels. - Mark]

Calslock Portable Door Lock

I have owned this tool for approximately two years. It manually locks an inward opening door. Ideal for travelling, students or anywhere that you would want privacy and security and there is likely to be multiple copies of the door key in circulation. I am on the road most weeks and have been walked in on in several hotel rooms by people with duplicate keys. I did some research and came across portable door locks.
It will not stop a determined attacker, but that is not what it is made for. It stops someone sneaking into your room using a duplicate key or bypassing the lock. A lot of hotel rooms have security chains, but there are videos on the web showing how these can easily be defeated. It also works on doors with no locks, aslong as there is a recess in the door jam where the door catch fits you can use it.

I originally had a similar one to this that I lost. When I went to replace it they had stopped production. I tried having tried several other designs but was never happy, then came across the Calslock one. At the time I purchased they only appeared to be sold on eBay, which worried me, but having purchased one there was very good service and it is an excellent product. (Still on eBay and cheaper than their home page!)

What makes this a cool tool compared to other portable door locks is a combination of things:

- It is a very good design, slim enough to fit doors that have a very tight fit.
- Easy to operate quickly if you need to get out in an emergency.
- Very adjustable from the thinnest cheapest door to thick heavy fire doors, I have yet to come across a door that is outside it’s adjustment range.
- It is very simple, only two large parts so no small fiddly bits to lose or to go wrong.
- Finally it is cheap, only $9.95, including free postage in USA on eBay or $12.95 direct.
I have no affiliation with Calslock, but whole heartedly recommend their product.

Totes Compact Umbrella

When I got back from a trip to Europe, the one thing I felt I needed more than anything, was a good sturdy umbrella. After much research I found this small Totes umbrella. In my past experience, most small collapsible umbrellas were utter garbage. This is simply not the case here. I have had this thing for about 2 years now. I bring it with me any time there is rain in the forecast.

It’s slightly larger than most collapsible umbrellas (about 14 inches long when collapsed). The handle feels strong and sturdy in hand. It’s comfortable to hold for long periods of time. The auto open and close button works brilliantly and opens with strong force. When open, it is a full “golf size” umbrella, able to easily fit two people underneath. In the wind, there is a magical springiness to it that keeps it from being unwieldy. I’ve had absolutely no issues in heavy wind.

4AA Pack-Away Lantern

During a recent 27-hour-long power outage, we rushed out to find emergency lighting. While most people grabbed the biggest lanterns they could find, we centered on these handy Pack-Away Lanterns. They touted long run-times on 4 x AA batteries (20 hours on low and 8 hours on high), and they delivered!

We clipped three to our dining room light to provide plenty of light for card games. Then, we used one of the lanterns to provide overnight light for our cat that is scared of the dark (a true fraidy-cat!).

The lanterns are small, and the top pushes down for packing and storage. I throw one in my backpack any time I head to an event.

There’s a wire loop/handle at the top that folds flat, and a small clip that can attached to the handle. The clip could be used for attaching the light almost anywhere, like the inside of a car hood, a beltloop, or chandelier.
