        As mentioned by others, it'd be great for places that have regular power outages, camping with multiple devices, or kept by the sofa if there's no power socket nearby so you can charge your phone quite a few times before having to recharge the power bank again.

      At the max 22.5w, it will take 9h52m to charge the above amount.

      In summery, you will need 226 of these to charge your low end Model 3 from 0% to 100% *again, if no losses going from 9V DC to 230V AC then back to 350V DC

      It's a freaking chunk of C4 my friend, I would not use a relatively big one. Even one lapse of judgment left in the sun/heat of a vehicle, and this big boi will likely self combust and take your car with it (and whoever else inside).

        Even one lapse of judgment left in the sun/heat of a vehicle, and this big boi will likely self combust and take your car with it (and whoever else inside).

        What's the difference between leaving this power bank in a car, and leaving a phone or GPS or dashcam with battery in a car? What would make this self-combust?
        Is leaving 5 phones in a car more risky than leaving 1 phone in a car?

          That's a risk too, especially in the full sun or change in direction of the sun inside your vehicle. The difference is the potential destructive forces of the boom, be it a small or large battery pack.

          There's a reason why nobody uses lithium polymer crank batteries for vehicles, it's just too damn risky.

          • eug on 13/08/2021 - 13:38

            @Oofy Doofy:

            The difference is the potential destructive forces of the boom, be it a small or large battery pack.

            Is it an actual problem with widely documented cases, or is it just a theoretical concern? Can sunlight cause a cell to ignite, or will it just outgas?

            There's a reason why nobody uses lithium polymer crank batteries for vehicles, it's just too damn risky.

            Crank batteries are LiFePO4 which have far greater cycle life than lipo. It'd be economically silly to use lipo even if heat wasn't a concern.

            • Oofy Doofy on 13/08/2021 - 13:42

              @eug: The prices have really come down, and the lifecycles for the $ are there, and the increased runtime for utility power uses etc, but there is no way in hell I'd use one as a crank battery, even though a few companies have offered them in the past. Some still offer them now.

              The risk is of a very intense sudden fireball that quickly overtakes your vehicle. Yes this is a real risk.

              Those kinds of batteries are best used being constantly shaded, under 65c and as secondary/utility batteries, not as engine batteries.

                Yes, there is also a real risk involved with storing 60L of highly-flammable liquid in a plastic tank 1 meter behind you while driving and parking under the hot sun.

                The question is how risky is it? Power banks can self-ignite just like how cars can self-ignite. But how frequently does this occur, and is there really a big difference in risk or damage between a 20,000mAh power bank and 60,000mAh one?

                    Your original comment claims that this power bank is, I quote, likely to self-combust if left in a hot car one single time.

                    My question was, is there really a big difference in risk of self-igntion or damage between this power bank and a smaller one, or even a phone? Plenty of people have left devices like dashcams, GPSes, phones, tablets, and laptops in their hot cars. What makes a bigger battery more likely to self-ignite?

                    • Oofy Doofy on 15/08/2021 - 21:01

                      @eug: It's something to consider, that's all I'm saying.

                      I am just not a fan, I've seen what they can do when they fail. My phone I keep on my body all the time, very different from a separate battery pack. They don't even have to be left in the sun, just in a hot environment inside a vehicle and the batteries will expand and start leaking fluid which stinks like chemical death. Not a fan.

      Why?

      • Caped Baldy on 13/08/2021 - 09:01

        Batteries on powerbanks and phones have different voltages so you can't cleanly divide to figure out how many times it can charge your device.

          but powerbanks normally use the same voltage, so you can easily compare them.

              @Caped Baldy: Power bank cells are rated at 3.7V so the capacity of 60000mAh for 3.7V is correct. The problem is that other battery cells are not rated at 3.7V. Phones are often (but not always) rated at 5V, while laptops can be rated at other levels.

              For simplicity with the phones we use the following conversion. There are other factors including the conversion loss.

              3.7 x 60000 / 5 = 44400mAh

              • eug on 13/08/2021 - 12:02
                +1

                @Clear:

                Phones are often (but not always) rated at 5V,

                Not true, phones always give the cell's mAh rating. It makes no sense to give a 5V rating for a phone as they do not step the voltage up to 5V (for their core power-hungry components). Even if they did, manufacturers would rather quote the 3.7V rating as it would be higher - just like what power bank manufacturers do.

                The discrepancy between a power bank mAh rating and the number of charges you can get out of it is due to the inefficiencies in the boost converter in the power bank and the charging circuit in the phone - which is the conversion loss you mention. I've measured several power banks and the figure is almost always around 20%.

                while laptops can be rated at other levels.

                Laptops typically quote their battery capacities in Wh which skips all the confusion as it takes into account both voltage and current.

        • eug on 13/08/2021 - 11:52

          Batteries on powerbanks and phones have different voltages so you can't cleanly divide to figure out how many times it can charge your device.

          Yes, but the mAh rating of a power bank always refers to the capacity of the cells inside the power bank. So if it has 60,000mAh worth of cells, it is known as a 60,000mAh power bank, as useful as that is.

        Seems like you need to read the entire thread, essentially everyone is just learning about how power banks work and how capacity is measured.

        The only possible issue I can see is maybe ROMOSS handles fast charging inefficiently, but without testing other brands they might all be bad.

              • BargainKen on 13/08/2021 - 10:07

                @[Deactivated]: They're usually stacked 10,000mAh cells connected in parallel to increase capacity. The photos in that previous thread only show front on photos as I commented in that thread, no side view showing evidence of single cell only. Single cell packs are very easy to tell as they weigh a heck of a lot less than a double/triple cell pack like that.
                I also have Romoss 20,000 and 30,000mAh packs and they've been fine, though I dont treat my battery banks rough.

    Its just unfortunate it only provides 22.5W. This would be perfect for a USB-C laptop backup supply. If it could do up to 45W (20V x 2.25A) like their fast charging powerbanks can, I would buy it.

      Yes, not sure why Romoss makes such low output. I have the 40000 mah version and cannot do 18w charge if two devices charge at the same time.

    Size 180 x 83 x66mm. Not sure why this isn't on the product page.

    Jesus being that heavy and big, I think I would much rather zip tie 2 powe banks together. You get an extra redundancy

      I have absolutely no idea why you need to fat shame our Lord & saviour.
