My take on More Stations Versus EBs
When I first started out getting power stations for power outages, my motto was get another station not an Extra Battery. My reasoning is that one is none, two is one - in other words, if the power station goes on the fritz, the EB doesn't do any good. Additionally, for longer outages, one station can be charging (via solar, gas/propane generator or taking it somewhere that it can be charged via AC) while the other station is continuing with the power backup duties.Now that I have plenty of power stations, I have looked at extra batteries. About a month ago, I bought a Delta 3 EB because I had a screaming good coupon code that needed to be used or lost. Although when I received the D3 EB I had hooked it up to one of my D3+ stations and charged it, I haven't actually used the EB. This time of year I take more and more things off grid AC and use stations to power them, then solar charge each station as it is depleted. So, now I have taken my computer/wifi off the grid and use a D3+ to power them. It takes a little over two D3+ stations per day to keep the setup powered (so a bit over 2kwhs per day). Tuesday, I set up the D3+ with EB (which totals 2 kwhs) and Wednesday recharged by solar (setting up another D3+ to take over the powering duties). I usually have to keep a close eye on the D3+ stations while solar charging. I need to swap them out in a timely manner and charge another D3+ while there is still decent sun. Instead, with the D3+/EB combo, I could let them just charge up without worrying about switching out. Although this isn't th ehugest thing in the world, it does make things a bit easier in the long run. Sure, I could use one of my D2Ms to power my computer set up, but the D2M has a larger footprint, so won't fit on my desk nicely (and under it is a no go). Plus, the D2Ms have other jobs.I still stand by my motto of getting another station as to an EB to start with, but once you have a backup for your backup, an EB can certainly fill the bill.
