    Hi Paul; happy to share however this addresses my immediate requirement to provide overnight power to my C-Pap machine for when no electricity is available. My C-Pap uses 24V input low power and the Li-Ion power pack provides 24V so I donít even need an transformer, plugs straight into my machine. I checked the many reviews and lots of people report getting two nights use from a charge (1 is fine for me as I can recharge via my cars cig socket). Unfortunately not available to S A on Amazon, mine was delivered next day to son in Canada. See Amazon link for full details and specs: https://www.amazon.ca/dp/B078T7M9HZ/ref=cm_sw_em_r_mt_dp_MG2KJXW4ZN77WXPJ01QD?_encodin g=UTF8&psc=1

    Much bigger battery, very nice quality, and a very competitive price.

    This looks like a good unit.
    Estimated price?
    I just wonder why we still see mini USB chargers of 1A. Most devices need a higher charge rate.

    It does have a 2.4A fast charge USB port. If I remember correctly price around R 7900.00

    some Rhetorical question:

    If you exclude the price of portable battery power packs for the moment-

    what are the chances this is the way one might go in the future - if you don't already have a DC -DC set up.
    So much easier to pack for traveling, use at home during load-shedding. Much lighter to lift. Far less components to put together to get a workable solution, for those challenged in the electrickery department?

    If you start from scratch and build a Victron set up with Blue Nova 108Ah Lithium battery - the cost is close to 20k anyway.

    Thoughts?

    And here's a lovely neat little box with 2400wh for camping - on special too! (buy 2, charge one while the other is in use)

    One of the brands Will Prowse is mentioning in a video about CROWD FUNDING which he no longer supports.

    I have to agree on the method crowd funding seems to operate specially when it is established companies as he mentions.

    I absolutely agree and Will has some really good videos - my post was meant to be sarcastic. I should have added some roll - eyes

    If you saw the special - it came down from 51k - REALLY? Besides the unit having some issues (very clear if you look at the specs) - TakeaLot also take us for a bunch of fools. FMG

    In the past month or 3 these portable battery boxes are popping up like mushrooms.

    On paper it looks good and yes I did not see sarcasm.

    Here's a thought.

    The Jackery is about 500Wh and the Lithium 444 is about 400Wh of stored energy.

    A Blue Nova based system would be about 12000Wh of energy.

    Makes you think, doesn't it.

    Keith you lost me - I don't know where you see the 12000Wh ?

    I looked at the Blue Nova 108 ah and it says on the battery it is 1400 wh?

    I am also finding it a tad confusing as with my AGM battery - I talk about 105ah. Now with Lithium - do we talk about wh?

    While I don't see the portable battery boxes as particularly workable for overlanding - I still want to understand it. Or maybe it will be if it is like 260ah...

    Please help me out here

    Oops, one extra Zero, so 1.4kWh.

    AH is only half the story and tells you close to nothing. When somebody quotes AH it is meaningless unless you also quote, at what voltage.

    Unfortunately we have gotten into the bad habit of using AH, primarily because we ASSUME a 12V battery

    Wh gives us the power (more correctly ENERGY) available to do work. Using Wh instead of AH leaves us free to specify a systems performance, independently of the systems working voltage.

    Flexopower is replacing the Lithium444. It was introduced in early 2018. Back then Flexopower and GoalZero were the only portable power packs in SA. The Li444 has reached end of product life and is being replaced by the Lithium555.

    The Li battery of the Li555 can be replaced once cycle life is used up, instead of buying a new unit altogether. Some key features are published on the SA website, it will be launched in May.

    555 looks nice. I like the ZA plugs - just hope they are modular so you can swop them out for the coming new standard plug.

    I wonder if the 555 size will still be ammo box compatible. The 444 you can easily fit in 2 plus all their bits and bobs. Maybe even 3, without their extras.
    Make it happen!

    How much heat does these battery banks give off?

    My intention is to connect my fridge in the rear to one, and drop the battery bank somewhere below one of the front seats (Discovery 4) and leave it connected to fridge and car, if it dies it dies, if I drive/start it charges...

    Flexopower looks like the best option so far.
