I recommend this more for back up battery power bank use because of the smaller capacity. if you are running a fridge or something like some others plan to do I think it's better to go for the 24Ah or higher capacity.
smaller 12Ah capacity also means decent charge time of ~4 hours (only around 2 hours wait if charging it from 50%) compared to the 24Ah which takes 7 hours.
already bought this one and tested. so here's my feedback. I don't plan on using the cigarette lighter port so just USB power use.
in the box: power pack, USB-C cable and manual.
obviously LifePO4 is heavier than Lithium ion so it does feel hefty.
charging indication with 4 LED's is a bit vague as I saw in a video before purchasing and charge indication is as written in the user manual.
so the problem is how to tell if it has a full charge or not. with all LED's solid it's still charging, because the final LED only indicates it's between 70% and 100%. (if you are used to most charging indications you would think the battery is fully charged but no all LED light up at 70%)
I can tell it was still charging at decent power because the 65w USB-C power adapter I was using was still warm to touch.
without a USB-C power meter, you can't really tell when it hits 100% even if the USB-C charger is cold the Kings could still be at 90 something %.
either need to use a USB-C meter or estimate and set a timer is your only option.
USB-C port also felt a little wobbly when pushing a cable in. I dunno I'm used to my USB-C ports never wobbling. a bit concerning long term if that port is used to both charge the pack and charge other devices (in/out function).
just to test charging my ipad via USB-A port it cut power at 95%. honesty 95% is good enough but I think USB-A at 5V the current gets too low because replugging ipad and the power pack turns off after 10 sec again. second test I charged ipad with USB-C port this time it charged fully to 100% and power pack even kept the power on at 100%. good đź‘Ť
because USB-A cuts power at 95% ipad charge, I think you won't be able to charge small battery devices like TWS earbuds on their own. if you want to charge very small devices I think it will work if you plug it in while you are charging something else via USB-C. so the power pack sees more current and keeps power to USB-A even during super slow charge with that port.
other than that it is handy to have something to charge larger battery devices with and also have enough left over to give everything a charge during a black out. that's why I got it anyway. LifePO4 also gives more total cycles than Lithium ion so batteries inside should last long term.
If you plug your USB changer into a common watt meter like this type: https://www.ebay.com.au/itm/374414579279?itmmeta=01J3599YMBN…
It will drop down to 0 or close when its fully charged,
