    Boondocking as a Digital Nomad

    What kind of laptops are we talking about here that don't have any compatible DC chargers? I'm curious enough that I'd be willing to do the research to find you some. I encourage you in your experiment to charge without the genny. If you find you do have to revert to genny-assisted charging, the most efficient way to do it is to run the gen in the morning when the batts are deeply discharged, and run any other house loads you have then to keep the genny loaded up. When the bank hits Absorption voltage (Vabs, 14.6v or whatever) kill the gen and let the the panel handle absorption and float. Those later stages take time but ever-decreasing amounts of current; perfect for solar and wildly wasteful on genny. Note: alternator charging can be used to good effect the same way. Run any errands in the morning and let the alt slam current into the bank. I will suggest that 160w of panel on its own (absent genny or alternator charging) is not enough to fully charge any deep cycled 6v-based banks I've ever seen. Not enough hours in the day. Even if the batts are on the smaller end at ~200Ah 160w is still undersized unless assisted. The general rule of thumb is in average insolation (intensity and duration of sunlight) one needs at *least* 1W of panel for every 1Ah of lead acid bank. 1:1.2 <-- 160w of panel to 200Ah of bank 1:1 <-- minimum if the sun cooperates 2:1 <-- should be find for the average bear 3:1 <-- handles heavier loads, or rainy areas like the Pacific Northwet. :-) Adding another 160w panel would be 1.6:1, much more likely to get charged with solar only.

    Comparing stream rates

    To some degree you can control the bandwidth the video consumes on Youtube and on streaming platforms like Netflix. I don't know about Sling or DirectTVNow. Ned's encode will be smaller because it is shorter (no commercials). If you want to go under the hood with youtube-dl you can exercise a great deal of control in format, audio, bandwidth, etc.

    No more Verizon 3G mifi

    Same. I got my money's worth out of the mifi, though. My flashed smartphone is still working. Dunno if they are excluded from the death sentence or it just hasn't hit yet...

    Strong Signal - Low Bandwidth

    I run everything off a 3G mifi with limited bandwidth. It does require some adjustments. Here's an rvwiki article on dealing with limited bandwidth.

    Beginner's Guide to RV Trailers

    The title of the thread, however, is "Beginner's Guide to RVs". I think that's the source of at least some of the discord. Psychological priming and all that.

    When I was FT in a travel trailer my ears were calibrated to the sound of emergency sirens. :-P For boondockers in small rigs FTing could be an upside regarding predictable severe weather events. Vandwellers, for example, tend to watch for and follow good weather because of their limited HVAC.

    Best boondocking batteries?

    The important difference with solar/gen charging is that the LiFEPO4 will not have an absorption period in the normal sense. This greatly simplifies charging. Here's what I mean. Generator (or alternator) charging with lead is usually one of these scenarios: charge with gen/alt until absorption is finished. This requires a long duration with minimal current; an inefficient use of a generator. charge with gen/alt until bulk is finished. This is great for gen efficiency but leaves the batteries at less than 100% SoC, which is damaging to lead chemistries. charge with gen/alt + solar. A good combo because gen/alt can do the heavy lifting in Builk then solar can handle the long duration / low current work. The first two problems go away with LFP, and having [gen or alt] + solar as in #3 is still a good combo. But here is something to consider... [CAVEAT: I am still wearing out my golf carts so I don't have LFP yet. The following is a theoretical approach to #3] Gen/alt are by definition intermittent sources of charging, so we can charge LFP all the way (13.8v?) if desired and let it fall back; no danger of holding at 100% SoC too long. Solar is a relatively constant source of energy so it may be productive to reduce solar charging setpoints to whereever we want the bank to hang out most of the time. 80% SoC? 60%? 50%? I suppose this would be a function of capacity and overnight loads.
  11. Well, there is no way for the user to know without seeing the dumpfiles (from darknet or similar). The site knows because it's parsing the dumps. In some cases, like the 500k accounts exposed in an earlier Yahoo hack, the passwords were stored as plain text and so are directly accessible in the dumps. In some they were unsalted hashes which makes it harder; common passes would be identified at once from password and common language dictionaries. Salted hashes usually make it impractical to crack for normal value targets.

    Single data device - where's the deal?

    I'd start reducing bandwidth with some simple changes and see how close that gets you. Add money to the mix only if conservation doesn't help. :-)

    A dumb charger that just has a target voltage doesn't have a Bulk stage. It doesn't have any stages as far as I know. A normal three-stage charger with a Bulk stage will be constant current / rising voltage during bulk up to the absorption setpoint. I don't seem to be alone in this opinion (Forgive the formatting in the following quotes; I could not paste as plain text in this browser): from Battery University: from Trojan: from Iota from Chargetek: What am I missing?

    I don't understand how Bulk stage could have a voltage setpoint set too low when it doesn't have a voltage setpoint. Bulk is constant current rather than constant voltage, right? My guess is J-T meant referring to the absorption voltage setpoint being too low. If the broader point is that "OEM converters generally fail to charge batteries properly" then I'm on board with that. :-) Don't know if I mentioned it in this thread or elsewhere, but I got around the problem by homebrewing that functionality out of a 24v power supply and an inexpensive-but-configurable MPPT charge controller.

    Every sentence in the above quote defies my understanding of the terms and experience with the components. I admit the possibility that I am just be seriously confused. :-) Here is my take: PD says this about the purpose of a converter: "The power converter recharges the battery and supplies 12-volt power for the lights and appliances when 120–volt AC power is available." They do not mention the absence of batteries. A converter is only on when connected to shore power, and may have a power switch, depending on model and producer. Always on does not mean always charging. Indeed, in the proposed batteryless system there would be nothing to charge. there is no bulk voltage that I know of, as bulk stage is current limited. Perhaps you mean Absorption/acceptance voltage here? I do not understand the claim that a converter with 3 stage charging is not a charger by any usual definition. PD even calls them converter/chargers. Bluelghtning's question and comments is more like what I would expect.
