Your Thoughts on Best Powerbanks

[Macrobius]

Not looking for a single device to cover every use case here. Some of the different ones are:

1. [communication device lifetime] ability to charge multiple mobile devices and keep them running 24-72 hours (depends on individual device needs of course), with our without #4 below

2. [emergency power] ability to keep single devices, such as medical equipment or small HEPA filters running overnight (8h) is a power outage and/or camping scenario with no on-site electricity

3. [backup power] ability to meet minimal household needs for 48 hours without power.

4. [off grid recharge] ability to recharge some or all of the above devices with only solar or car-based power supply

Most of these power banks are very expensive for what they actually are. The jackery “electric” generators (everybody knows they don’t generate anything) in particular are very expensive for no real benefit.

Might want to build your own battery array as the cost for large cells is relatively cheap per kwh.

What sort of cells would you use for a basis -- high density Tesla style batteries?

You could use some LiFePO cells. Usually for a powerbank you use whatever batteries you can get your hands on. For instance, if you know a place you can get some old lead acid forklift batteries those have more than enough amp hours in them that 5-10 should keep a house running for days at a time. If you have access to a large number of car batteries that have been discarded; wiring them up and trickle charging them is somewhat trivial. New cells are obviously going to be better than old cells unless you can get very cheap old batteries that still have the potential to get a charge.

General Battery Discussion

Anything and everything batteries!

I'll defer to posting a link to another forum. But let me put a little bit more time into thinking about this. I have seen quite a few different off grid setups in person and the biggest thing I can say is that no two of the powerbank solutions are going to be the same. Something else I noticed is that nobody stores their batteries inside their main home, they always construct something away from the house. Consider that as well.

Electric bicycles can store a decent amount of power and can also be useful I think in some kinda grid-down/SHTF scenario, for light trips to conserve precious gas/diesel. They typically hav a USB power point you can use for low current but the Hailong type removable batteries can be easily adapted (with no hacking of the batteria pack itself) to run DC applications up to at least 1500w

Building an array of old lead-acid batterias is something worth exploring, if you can get them for marginally higher than what theyre exchanged for at the AutoBone. I stopped exchanging mine out but hav yet to explore any further than using more than two in parallel for storeage

The most basic setup of course is a single lead acid 12v batteria with an inverter to convert 12VDC to square wave 120VAC. Some are really cheap (like 10 ZOGBux)

Inverters are shockingly enough cheaper than you would think. A nice high quality inverter can even be had from Harbor Freight of all places (As of lately Harbor Freight has been improving their imports and has far vastly improved the quality of the zogcrap and tools you can buy). I'd also consider maybe investing in a trickle charger if you wanted to construct an array. Keeping up voltage is an endless battle with batteries and having at least some small amount of tie in to keep the voltage high is better.
