Black & Decker VEC010BD Start It 300 Amp Jump Starter Review

Black and Decker VEC010BD Start It 300 Amp Jump Starter

This is a nice unit for starting cars, as noted below. But it may be too small for some other 12-volt applications. The lighter-socket outlet will shut off if you exceed 5 amps of continuous draw. At 12 volts, that would be 60 watts, and as luck would have it, my laptop PC requires 90 watts (7.5 amps) when plugged directly into a 12 volt source.
Also, in terms of total amp/hours, it would not be able to power something like a CPAP machine for a full night's use, which some people might like to do on a camping trip or the like. The description touts the unit's non-automotive power uses, but they are really somewhat modest. Charging a cell phone is not much of a challenge!
It works fine for starting cars, though. This appears to be identical to the Vector VEC010S, which is the unit I have. ("BD" at the end of this product ID is obviously just for Black and Decker's labeling on the front).
My car battery went dead in mid-winter, and I thought it was shot. A neighbor had this same unit, and in the spring I borrowed it twice to start the car, which went fine, even though his unit wasn't even fully charged when I borrowed it.
Finally I bought my own, charged it overnight as per the instructions, three hours past the blinking green. When I went to jump the car, for some reason it would not start right up as it had the other times. On the first attempt, the car turned over and over, but wouldn't kick in, and the effort drew down the jump starter's cranking power to zilch. Everything stopped.
The car had not cranked long enough to become flooded, so that was not the problem. I suspected that I might not have set the clamps correctly to get a "clean" grip, and that this reduced the power available for cranking.
The instructions tell you to wait a little after long cranking, so I did. I also reset the clamps (which are perfectly strong and fine, by the way!)After a few minutes, the unit had regained some of its cranking power, and it got the car going easily.
Back inside, I plugged the starter back in to charge up, and it took several hours to get back to full (blinking green light). Apparently, getting the car going had used quite a bit of juice.
The next time I needed to jump the car, it was instantaneous, and I performed multiple jumps without needing a new charge. So, unless there is something unusual about the first usage, I suspect that my placement of the clamps was to blame. The well-written instructions are clear about the need for a good connection, after all.
If you do want it mostly for jump starts, and do not expect to need it as an "emergency power" source for long hours, or to run any kind of serious appliance, it is a fine choice.

Tripp Lite SMART1000LCD Digital LCD 1000VA Line-Interactive UPS (8 Outlets) Review

Tripp Lite SMART1000LCD Digital LCD 1000VA Line-Interactive UPS (8 Outlets)

We are using this unit more and more in the field. I have one on my desk and one for my rack of networking and satellite equipment at the house. The battery display is great when the power is out. Imagine this, I was able to goto the website for my power company to get their phone number when the power went out last time.
As for the previous reviews, here's a couple things to consider. Like most ups, half of the outlets are surge and battery backup, the other half are just surge protection. Now the surge protection only side is great for things like speakers and printers, but if you plug your computer into the wrong side, you won't get the battery backup feature. APC actually started putting big yellow stickers on their UPS because of this.
And the power and heat. Yeah, it gets hot, when it's charging. It's warm when its fully charged.. But it doesn't continously pull 1A of power. I'm sure it does when it's charging, but my fully charged unit only pulls 5 to 20w of power or 50 to 160 Milliamps of power (.05A - .16A). Checked it myself with my power meter.
In all, this is a great unit and for 1000VA, it's a good deal.
