Black & Decker VEC010BD Start It 300 Amp Jump Starter Review

Black and Decker VEC010BD Start It 300 Amp Jump Starter
Average Reviews:

(More customer reviews)
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.

Schumacher SE-5212A Automatic Handheld Battery Charger Review

Schumacher SE-5212A Automatic Handheld Battery Charger
Average Reviews:

This jewel is very light to pack a 50Amp punch. I connected it to a battery insufficient to turn over the starter. The guy working on the house left his light on in the truck bed. I connected the charger to the battery while in the 2Amp mode, then plugged the battery charger into the 120VAC receptacle. I then switched it to the 50Amp selection and allowed to charge the battery for 4-5 minutes. While the charger was still connected to the battery, the guy was able to start his truck. Man was I blown away. Following the instructions, I changed the charging selection switch to the 2Amp mode, disconnected the charger from the 120VAC receptacle, and then disconnected it from the battery. How sweet - no arcing, no sparking. This is a must have!!! Excellent value and quality.

Battery Tender 800 Waterproof 12V Battery Charger Review

Battery Tender 800 Waterproof 12V Battery Charger
Average Reviews:

(More customer reviews)
Deltran Battery Tender 12-Volt 800 milliamp Waterproof Battery Charger
The Battery Tender Waterproof Tender operates in essentially 3 stages. It first initiates an absorption charge that attempts to charge your battery to 14.5 VDC at up to 0.8A (or 800mA). This bit of information was not readily advertised, so I was concerned when I heard my battery making gurgling noises while the LED was "amber" for the past 8 hours. This battery was only 2 years old with less than 5000 miles and had been maintained since day 1, so I was sure it wasn't a problem with the battery. It turns out that it was nothing to be concerned about since this charger was designed to be used for long-term storage of batteries.
My previous charger, a Black & Decker / Vector 2A "smart" automatic maintainer tried to keep my battery voltage at 14.75 VDC at 2A for over 24 hours. Needless to say, I was concerned when I saw this happening with a brand new Battery Tender. I dug around on their website and discovered a PDF that indicated the Tender would try to reach 14.5 VDC for the absorption phase, at which point it would switch to a trickling charge and finally the maintenance charge. I logged all of the readings and confirmed that once the battery reached 14.4-14.5 VDC, it would start to trickle down finally remaining at about 13.12-13.22 VDC @ 20-100 mA. A modern car's parasitic draw is about 10-50 mA, so the maintenance charge is to compensate for the parasitic draw and for self-discharging of the battery. I discovered the Tender does a much better job at a maintenance charge because I have yet to see the Tender go into the Amber-LED mode, whereas my Vector/B&D occasionally switches back and forth even on a fully charged battery. I logged some data from the Vector/B&D and discovered that once the LED is green, it provides NO current to the battery. In essence, the Vector/B&D just shuts off once it reaches 14.5 VDC - which is not as useful as providing an actual maintenance charge. The Battery Tender wins. Quite a few people have commented that their Sears "smart/automatic" maintainer and other brands constantly switch between the Green and Amber modes. I suspect those chargers are doing the same thing as the Vector/B&D. They just shut off when the battery is "charged", which is not very good for the battery. It needs to hold a maintenance charge to prevent sulfation.
The Tender Waterproof is fully encapsulated with a thermally conductive potting material. This makes the unit quite heavy for such a small device. It uses a quick-disconnect 2-terminal fitting that is commonly used for battery chargers/maintainers. It comes with ring terminals or large battery clamps all fused with a 7.5A ATC fuse. I made my own wiring harness with smaller alligator clips since I don't have room under the hood for large clamps, and I do not want to permanently install a set of ring terminals that can short out or cause other problems in the long-run.
Pros: Battery Tender has an excellent reputation for making reliable chargers. The Waterproof unit is quite durable and is insulated from shock, water, corrosion, extreme temperatures and other environmental variables.
Cons: At 800mA max current capacity, this charger will work rather slowly for 50Ah or larger capacity batteries, so expect 10-12 hours upon hooking it up to a battery before the LED turns green. The benefit of this is that it prevents boiling the battery or generating a lot of heat due to excessive current.
Overall: If you're using the charger in an environment subject to cold or hot temperature swings with plenty of moisture, such as in a detached garage for your motorcycle, boat, stored vehicle, or even a daily driver, I highly recommend the Waterproof unit over the Tender Jr or Tender Plus.
UPDATE:
I decided to purchase an additional Battery Tender Waterproof because I needed another charger for my daily driver and because I experienced no problems with the first unit.

Sunforce 7 Amp Charge Controller Review

Sunforce 7 Amp Charge Controller
Average Reviews:

(More customer reviews)
Bad:
Really cheap quality. Included instructions don't provide enough information. Website is just as un-informative. Cheap connector wires (low current), and is not equipped with screw-on terminal junctions.
Good: Product works as advertised. Amazinlgly "regulates" the voltage to the required amount so as not to overcharge the battery. Beware though, in order to test the actual output voltage, you must apply a load on the battery end of the controller BEFORE. Failing this, the output can register volts as high as 20 volts !!! Apparently applying an actual load causes the controller to output the correct voltage range - lucky me, cause I bought 4 units ! The LEDS alternately flickers (fast for good voltage input and slow for low to no voltage on solar panel). The manual did NOT state the order of LED flashes.
(1) Fast LED flashes - good voltage/current
(2) Slow LED flashes - low/no voltage/current
(3) steady Green - fully charged
(4) steady amber - possible no load OR really low voltage/current
I recommend you go out and buy 'em. The are a really good deal and does the job at the best price ! I use them in Jamaica, to provide my appliances with power during power outages (very frequent here). Used with solar panels and DC to AC inverter, of course. Considered using a generator, but too many accidents here with generators, too noisy, too bulky, and during hurricane aftermath, fuel is a problem. Solar is freely available, so it was the BEST option all round.
Hope this helps all readers !

Schumacher SE-125A Automatic/Manual Onboard Battery Charger Review

Schumacher SE-125A Automatic/Manual Onboard Battery Charger
Average Reviews:

(More customer reviews)
I've owned this charger for 5 years. It has a "manual" function, meaning that you can charge a battery past the normal 80% that the automatic chargers will. It means you can also charge one more quickly because the automatic function (also on this unit) of most chargers tapers off the amperage sent to the charger as it reaches 80% of charge. (15 amps also goes faster than ten.) Manual means you can also "condition" a battery to get the sulfites off of the plates, by carefully charging and watching to the point where the battery plates begin to gas off. Means a battery will take and maintain a better charge and last longer. I use it on the RV cabin battery for this, but also use it regularly just for car stuff.
All this and it does what other chargers do. 2 amp trickle charge, high powered capacitor starting function.
I DROVE OVER THIS CHARGER WITH A 5000 POUND 1986 LTD CROWN VICTORIA TODAY! FLAT as a pancake. Ahem, well. First plugged it in and promptly blew the garage circuit breaker. Immediately started hunting for other Schumacher chargers on the net. After spending two hours and seeing this particular unit is now over $100 new, thought "Well, let's see if I somehow tear it apart and look." No sooner got the mangled housing off, and (uuuhhh!!) bent the back upright (which had a circuit board on it), plugged it in, and it works!! And, in the course of bending back the heavy steel housing, NO paint flaked off. Must be baked-on enamel. These babies are built tough. As another reviewer for Schumacher chargers said, "No repackaged imported junk".
I take my hat off to this company: features, durability (!), quality........ wow.

Sunforce 50033 15-Watt Solar Charging Kit Review

Sunforce 50033 15-Watt Solar Charging Kit
Average Reviews:

(More customer reviews)
Hi- I bought this set-up to keep my Motorhome charged when not using it. It is only 15 watts so can barely keep the battery up to charge if I am actually using any lights or other stuff but it will keep up with the draw of the refridgerator and minimal stuff. My only beef is the controller wires could have all been pre-terminated with connectors rather than having me do that. This was bought as a kit so it would have been nice if there was a connector on the input side of the controller that mated witht he connector on teh solar panel and a different style connector on the output that would be compatible with the cigarette-lighter adapter, etc. In other words- all set up to just plug in and go.
Once I soldered and shrinkwrapped the new connectors on I'm pretty happy with it. Not everyone has the ability to properly terminate the wires.
Thanks

Sunforce 81095 Solar Shed Light Review

Sunforce 81095 Solar Shed Light
Average Reviews:

When the factory-charged batteries ran out the solar panel would not charge the light. This was a fluorescent version. The replacement unit- quickly sent by Amazon -was LED. The same case and everything but with bright LEDs inside. I liked it much better than the fluorescent one.
The second unit charged and worked very well until the charge was depleted. Then the LEDs would start blinking. Like an emergency light. Sunforce said that this was not normal behavior. I returned it as well. The light will stay up for around two hours, charge quickly but the blinking made it unfit for continuous use. A nice product but quallity needs to be improved.
