RE: 12 v to 12 v trickle charger

Your 2.0 volt differential claim, is simply absurd, and shows you have Zero experience with such a product. Perhaps long ago with older less efficient transistors a 2 volt drop could be expected, but certainly nothing like offered in Mr wizard's link.I'm a retired electronic tech and have worked with many types of power supplies. Granted, my experience may be a bit dated, but the simple fact is you will not be able to charge a 12 volt battery using a 12 volt source. The charge voltage has to be higher than the battery voltage. Even if the voltage differential was zero volts you will never get more than 12 volts out of the buck converter. The specs for the buck converter that MrWizard mentioned are: Input Voltage: 6V to 40V DC(10V to 40V is suggested) Output Voltage: 1.2V to 36V DC The output voltage will never be higher than the input. At the high end the voltage differential is 4 volts. At the low end it's 4.8 volts. At mid range the differential probably is much less but will always be greater than zero. The simplest solution is to use a boost converter.

RE: 12 v to 12 v trickle charger

Drok dc to dc converter https://images-na.ssl-images-amazon.com/images/I/61u8CjciEkL._SL1001_.jpg width=640This is a buck converter. What is needed is a boost converter. A typical buck or boost converter needs a two volt differential, meaning for 12 volts in a buck converter will have a maximum output of 10 volts. For boost the minimum output will be 14 volts. Or you could get a buck/boost converter which will function as either with no voltage differential.

RE: 12 v to 12 v trickle charger

Expanding on MrWizard's DC-to-DC converter idea, you could make your own charger by using a boost converter connected to a cheap solar charge controller. https://m.media-amazon.com/images/I/61XbaZIrs6L._AC_UY327_QL65_ML3_.jpg height=100 150 watt boost converter from Amazon https://m.media-amazon.com/images/I/6154caE0IcL._AC_UY327_QL65_ML3_.jpg height=120 7 amp solar charge controller from Amazon Set the boost converter output to about 20 volts and the charge controller will prevent overcharging the battery. Connect the battery to be charged first then apply power to the converter.

RE: Winegard Wingman

EDIT--now that I have played with putting the Jack on and off, I think you can just put the batwing with Wingman on the other way around so the Wingman sticks out the other side.The Batwing can not be turned around. When I installed my Batwing there was no room to stow it to the rear so I mounted it so it stows to the side. It has been this way for 9 years and have had no problems. The Winegard Sensar IV aka Batwing is considered the best RV antenna. It has the best VHF performance of the lot. About 25% of US TV stations are now broadcasting on the VHF band. Because of its small size the Jack does a poor job of receiving VHF. Here's a link to an extensive test that SCVJeff did a few years ago: https://www.rv.net/forum/index.cfm/fuseaction/thread/tid/27171026.cfm The Sensar Pro is a great improvement over the basic wall plate but is not required. It has an adjustable amplifier that can give you 10 db more gain and also has a display for signal level which allows you to find the best direction for the antenna.

RE: Heave-Ho

The OP never stated that the propane fridge did not work. It would make no sense at all to go through the work to reinstall a non working fridge.

RE: Phone as Hot Spot

The battery can not be removed from the ZTE R2 (at least not easily). I have had the R2 since June and the only time it's not charging is when it's in my pocket. So far no problems.

RE: Flip Phone

The issue is not about flip phones or who sells flip phones, the issue is that Verizon is terminating their older 1-3G networks and non HD portions of their 4G and LTE networks.The OP's present flip phone is a Kyocera Cadence LTE which is 4G LTE.

RE: Need Good Sources for Quality Bulk Solar Cable

If this is a permanent install you don't need connectors. Just wire direct from panel junction box to combiner box. Any connector will add a bit more resistance to your run. If connectors are needed, I would suggest using Anderson Powerpull SB50 connectors. The contacts can be crimped or soldered. https://powerwerx.com/anderson-sb-connectors-sb50-50amp https://powerwerx.azureedge.net/powerwerxpictures/sb50-sb-series-50-amp-anderson-powerpole-kit_580.jpg height=200

RE: digital photo storage

For those that need definition -- SSD is a hard drive, but Solid State Drive, nothing to fail, no internal fans or moving parts.I've had more solid state devices (SSD, USB thumb drives, SD cards) fail then mechanical hard drives. Nothing is 100%.

RE: My generac diesel generator only runs with prime button

Since the generator runs while the prime button is pushed, this pretty much rules out a fuel problem. The following is info for a 75D model: Engine starts then shuts down when Start/Stop switch is released. I assume that the Prime button ties in with Start/Stop Engine oil level is low. Defective Low Oil Pressure Switch. Defective Coolant Temperature Switch. Defective Control Module circuit board. Coolant Level is Low. Defective Low Coolant Level Switch. Defective Start/Stop switch. No A.C. output. Defective engine control board. If no A.C output: Reset main line circuit breaker. Generator internal failure. Generac discontinued manufacturing RV generators several years ago, so servicing and obtaining parts will be a challenge.

RE: Jayco TV antenna

So when I turn on the booster and get a few pixalated pictures and 2 stations nothing else to do but get a satellite.You most likely need a better antenna. The Winegard Sensar IV is considered the best RV TV antenna. You will have to drill a hole through your roof to install it. The instructions say to install it so that the antenna stows to the rear. This would not work for my installation so I positioned it so that the antenna stows to the side.

RE: Mobile hot spots

Does anyone know if you can have more than four members join your party?Party Pay can have no more than four members. This brings the monthly payment down to $25 which includes all taxes and fees. I've been on the plan for a month. Your account remains private. Anybody can join the plan. Visible Party Pay Here's a site where people post Party Pay spots: https://www.reddit.com/r/VisiblePartyPay/ Visible is a Verizon owned company and uses Verizon towers.

RE: 50" - 55" TV... Uses 55 watts or less.

Usually the labeled watt rating is a peak value. The average would be less. About the only way to know the typical wattage is to plug the TV into a meter like a Kill-A-Watt.

RE: Will solid state batteries change the world?

The biggest problem is "refueling". You can fill up a gas powered car in a few minutes. It will probably take a few hours to top up a battery powered car.

RE: weak antenna signal

To clarify this a bit, the government recently auctioned off the 600 Mhz TV band leaving only channels 14 thru 34 in the UHF band. Nothing changed with the VHF band. Back in the old days of analog you could not have adjacent channels in the same market. For instance, you could not have channels 2 and 3. But wait, you say there are channels 4 and 5 or 6 and 7 in your city. Turns out there is a frequency gap between these channels. This basically cuts the number of channels available in half. Now with the advent of digital, adjacent channels are allowed, so the impact of the frequency auctions are not as drastic as appears. Most of these channel reassignments are within the UHF band, so most of the TV broadcasts will remain UHF. Before the repack about 25% of TV stations were broadcasting on the VHF band. I don't know what the percentage will be after the final repack.
