If you have electric, you should have one of these.

One of the most basic gizmos everyone needs.  I mean ... don't you already HAVE one or more?

I love having stuff like this in my kit. Its one of those things that when you need it, its a life saver. For the price of one at the local store you get 10.
Do yourself a fever and get a set of each style fuse even if you don't need them now.

Awesome. You could run a regular (probably orange) extension cord through your garage and then have your battery tender plugged into it on the floor and trip over it constantly or you could buy one of these extensions made for the tender and have it run along your ceiling inconspicuously or run along the baseboard of a wall out of sight and then have it come up right where you need it for your car, truck or motorcycle.

This thing is neat. It takes a little turning, but does what it says. You have to really get on it if you need a long charge/light or you have to constantly wind it, but it is invaluable in a power outage or Natura disaster

It's nice to have a power source that you can pull out when a plug is not available. Great for concerts or airports!

If you own an older house, then you've had the pleasure of changing fuses. In our little house that means groping around in the dark to find a flashlight so I can find the proper amp fuse. Half the time, the end result is a trip to the hardware store. With these installed, all you have to do is open the fuse box and press the button when it trips. No muss, no fuss, and no pricey bids from electricians to replace the fuse box. I just wish Bussmann made more than two sizes.

This is a great addition to your home in case of a power outage. I have two and they come in very useful.

Pretty cool that you can just crank it up and it'll work.  I bought this radio mainly for emergency use when electricity goes out.
I do wish it felt a bit better built but otherwise does what it's supposed to do.

I didn't know that my computer equipment was draining off over 100 kwh of electricity on idle power per year.  It's not going to save a lot of money, but knowing that turning off this kind of idle power helps the environment makes me feel good.  BB Standby just comes in very handy.  All it needs is one click of a button.

It may not have electric, but it does the trick and does it easily.

This is nice when working with a shorted circuit. It is better than wasting fuses.

Highly recommended (esp. compared to a wired iron and having to find an extension cable and outlet every time something needs soldering in an installation)

Go get yourself some Eneloop rechargeable batteries too, fast charging and great battery life in this thing.  Heats up faster than my 40W plug in iron does.

What can I say? This thing has been a godsend for breathing life into my old tools. As an electrician I use cordless tools every day. Combine this with some 5.0Ah batteries and you have tools you can use all day.

This is no run of the mill gadget. This is an excellent performing electric machine.  Time, health, email, notifications, you name it and you get it.

This will save you during short power outages and will keep your equipment running for several minutes at least if you have a laptop, monitor, etc.  This is not a replacement for a generator or a long-term use battery, however.

These are perfect for items you own that don't have their own On/Off switches. I have one plugged into an outlet that is used for an overhead light. Much nicer than using a pullstring. Also have one I use with my Foreman Grill. A few others for Christmas lighting, etc, etc.

A well-engineered product.  Save your battery.  Especially if it is in a car that you don't drive often.
