Customer Reviews

Definitely not waterproof or resistant!!I ordered the Blue Sea 4356 panel with USB outlets, 12v outlet, and voltmeter. It sat on the shelf for about 6 months until I finally was able to get my boat all back together. Overall I would say this was a great product. The USB ports seemed to charge just about any device. The lighted switch felt robust. The voltmeter read to the hundredth of a volt and the display is bright and clear enough to read in any condition. However, the positives end there. The jumper wiring was sub-par but was easily replaced. The biggest problem is the voltmeter is absolutely not waterproof or even water resistant per its IP66 rating. The second day the boat was on the water we had rain twice. The exposed panel seemed unaffected until I turned it back on the next day. The voltmeter showed 16+ volts (on a 12v deep cycle) and began to climb. After about 10 seconds it read slightly over 20 volts and faded out to black. Battery voltage tested 13.01v with a Fluke multimeter. The display has yet to turn back on. Further examination of the meter showed water under the faceplate, no doubt the cause of the issue. Now I'm stuck with a voltmeter that doesn't work after only two days in use, a hole that can't be used for another voltmeter (none are the same 1 1/8" size), and fearful of replacing the meter with another 1733 unit ($45-$50) to find it has the same issue.Don't waste any money on this if you think it will get wet!! It will not work again if it does! Keep it dry or find an alternative product. 1Good charger...unless you have an ANDROID deviceI purchased two of these units for my two boats after having a situation where I blew an engine 32 miles offshore and almost ran out of cell phone battery talking to the Coast Guard, family members, etc. The unit is well made (as is true of all Blue Sea Systems gear) and incredibly well priced. The problem is it will only charge Android devices at 300-500ma, which is almost not enough charging current to keep up with the voice/data radios, bluetooth, GPS, etc. As a previous (and VERY helpful) reviewer noted, you can open the unit to solder together the two middle pins on ONE side on the charger (the pins aren't evident on the other side, and I wasn't going to tear into the PCB to "fix" both sides). The hardest part is popping off the rear black plastic disc from the unit..you have to use an x-acto knife to go around the circumference of the rear disc and then gently pry up on it to get it to release from the threaded barrel. Once you have removed the rear disc (and voided your warranty in the process), the rest is a piece of cake...simply find the two MIDDLE pins on the one side and solder them together. There is a black insulation material on them which scrapes away easily. Once this is done, you can charge that ONE side at 1100ma on an Android device. All that being said, if you have an Android device, you would be better off simply buying the 12V blue sea cigarette adapter and then getting a cheap plug in charger that is capable of high speed Android charging. Blue Sea recommends using a high speed charging cable to rectify this issue. I bought a very expensive dedicated "high speed" Android charging cable from amazon, and it made zero difference. In short, if you have Android, stay away. I write this to help somebody out there, since I was greatly helped by the reviewer that initially described (and photographed) the necessary modifications for Android charging. Off now to tear into the second unit... 3My sample is quite goodFirst, the unit I received appears to be exactly as listed. It is not a 12V power jack with a USB power adapter stuck in it. The USB ports and power converter itself is a black conformal coated module within the cylinder you see and mount. For marine environment use this coating is important as there is no other good way to moisture proof electronic circuits short of hermetically sealing them and using water proof input and output connectors. So except for the exposed connector contacts on the unit, salt air should not have much negative effect on long term reliability.I bought this to power the Bluetooth to RS232 adapter on my race car's Megasquirt ECU and the Nexus10 tablet that I use for the instrument cluster on the same car. The Nexus would not charge at above 500ma with this power port until I shorted the data pins together on one of the USB jacks as described by Mr Borosky. I have had to do this on a number of USB power ports to get more than 500ma. There is a recent USB charge port power spec that calls for devices connected to the charge port to simply increase current draw until the USB voltage drops under 5V in order to find and use the most amperage such a charge port can supply, but I dont own any that do this yet, but I have a couple Android devices that detect the shorted data pins.I power this USB power port (and thus the Nexus and Bluetooth adapter) separately from the ignition ON switch in the race car to reduce the time needed to have fully functional instruments upon engine startup. Because starter current demand during engine cranking will drop available battery voltage, and I use the smallest (and lightest) battery I can afford that will start the car, I wanted to know how well this power port would ride thru voltage sags during this time. I found the port will remain fully functional at input voltages down to 6V and the USB port outputs remain a steady 5V until the input voltage drops to close to 5V. Based on observing regulator switching noise on the power input, it appears the port drops out of switched regulation and into what must be linear regulation below about 7.5V because the switching noise on the input power wire completely disappears (and the green LED goes off, but the regulated 5V output continues unaffected until the input drops below 6V. This performance is more than adequate as my system voltage on the car does not drop below 9V during cranking if my battery has a decent charge. It also appears pretty robust in my view since some similar I have seen shut down at 9V and the outputs drop to zero volts.Because I have a number of unshielded analog sensor signals connected to the ECU and am using Bluetooth to connect the ECU with the Nexus/instrument cluster I was concerned about generated electrical noise from the unit, either radiated from the unit into the air or from the 5V outputs or 12V input. I found no discernable noise on the 5V outputs as seen on a 350MHz o'scope or radiated into air based on a handheld 140M-900MHz amateur radio transceiver set to scan that range (actually multiple bands in that range with some frequencies that are not tuneable). The 12V power input exhibits a 300KHz triangle wave with some 1MHz short duration ringing syncronized to the triangle peaks. The 300KHz triangle wave is under .2V p-p and the 1MHz ringing is under .4V p-p. Under some combinations of input voltage (7.5-15V) and load (0 to 1A tested) the ringing and triangle wave decreases or disappear entirely. At least one reviewer wrote that his sample was producing enough noise on the 5V outputs that the radiated noise interfered with reception on his marine radio. Based on how mine behaves, I would have to guess his was defective or a different product than the one I have. I found that a medium sized clip-on ferrite with the power wire passing thru and a 6800uf 25V electrolytic between the power port input terminals eradicated this from the 12V wire back to the power switch. 4Just got it, one design flaw so farSo, I got the 12v socket, just received it today. It is an add-on for the back of my SUV, and I like for things to look as factory as possible. So, my only complaint to this point is right away, I noticed that the included face plate in which two screws can be used for extra support is not manufactured correctly. It has the two screw holes and the socket hole inset to provide a secure and and nice fitting anchor. The plate that I received has the inset screw holes drilled on the wrong side of the plate...so one side has the inset for the screws, but the opposite side is inset for the socket. With the flexible attached cover, it won't work like that. I can use without the plate I guess, but putting this into a plastic trim panel in the SUV, the extra support would have been nice. I have not used yet, but this flaw makes me question the overall quality of the product. 2Excellent qualityThis meter is great to use even in direct sunlight. The unit installs in a traditional 1-1/8" hole. Perfect for monitoring my battery. I wired it hot so I can look in to check my battery voltage anytime. Excellent quality. 5Excellent for OEM replacement.Perfect for automotive applications. Fits easily in a 1-1/8 hole (even works if the hole ends up a bit bigger or has rough edges.The terminals are standard push on blade type, although it would be nice to have the positive labeled brightly in red somehow.Lock ring is a little difficult to tighten, and there s no way to actually lock it in place. A dual ring would solve this and actually lock it. Other than that, very well made and worth it.This isn t a fused socket, so you ll want to have some kind of protection if you re adding it directly from the battery. I replaced an existing fused socket. 5This is a really great product, and the only reason it doesn't get ...This is a really great product, and the only reason it doesn't get 5 stars is because out of the box it doesn't deliver the whole 2.1A that it claims. The USB ports aren't set up to tell the device you plug in that it's allowed to pull extra current, so it tops out at 500mA per port. Installation was very easy, but you'll want to use the right size drill bit! That outer flange with the two screw holes is removable and I ended up not using it, so my installation is perfectly round.A quick modification of shorting the two centermost pins on the USB port fixes the current problem (the spec says any resistance between these pins <200Ohms will trigger high current mode, if I recall correctly). Another reviewer has more detailed instructions, but basically you pry the back off (I found a small screwdriver in the slot next to the quick connect tab did the trick; it takes some force but it is possible to do without bending the quick connect. After that, everything slides out, you can see the USB pins on the back of the circuit board. I scraped the black conformal coating off with a razor blade then globbed some solder between the pins. I was only able to get one side though, the other is buried too deeply under the circuitry. And really, I shouldn't need to be modifying this at all! 3It's worth every pennyMy wife and I fish/boat alot and we're always bringing electronic devices with us that sometimes require charging. I added this in addition to our 12VDC socket already installed. It's a godsend. Only one thing you need to know about this particular USB charger socket. It has a little green LED on it that let's you know when power is supplied to it. Unless you have a battery selector switch on-board or you're planning on installing this device to a switched power source, this little LED will be on all of the time. The LED is so small I don't think it would considerably affect your battery while in storage.....just something to consider if you don't have one of the aforementioned options installed. 5Buy two or more. These are so useful.I just ordered two more of these. I have three other sets and use most of them often. I like having lots of places to plug in.Be aware, these do draw some power converting 12 volts to 5 volts, so if you don't keep your batteries topped off with solar panels or some other means of charging your batteries, these will draw your batteries down eventually. If you put them on a switch they won't draw any power. I have solar panels so I put more into my batteries than these will use--which is very little. It would take a month or two or even more to kill a battery by leaving this connected.The go in easy. I tape off the area, drill a hole. I forgot what size, with a hole saw. I seem to recall that I had to go buy a hole saw to fit it. Then I remove the tape which prevents splinters, and pop it in.The cover works well if you install facing up. For horizontal mounting I find it gets in the way. It will keep out the dust, so the cover is worth using.Shop around some people charge double.Buy two as they are very handy and it is as easy to install two sets as one. I spread them out so I always have one within reach.I'll probably buy several more. I don't like the type that plug into a cigarette lighter and vibrate loose. These always provide a good connection. 5Charges Fast; Water-Resistant; Looks Good w/Voltmeter PanelI bought this and one of those Blue Sea's "dual USB charger + voltmeter" panels. I switched out the cheap dual USB charger that came with that unit with this one (which charges twice as fast) and I love it. I would highly recommend doing that! Installed on the lower dash of my '00 Toyota Land Cruiser. I ran this dual USB charger and the voltmeter through a switch so I can turn it off while driving and night so the red digital voltmeter won't distract me. I also spilled an entire cup of coffee on this thing with the protective cover off and it still works perfectly. Gotta love it! 5
