Trev, I have posted before about these power packs you love to link to and how what they claim is total BS. Such as the 10 MILLION mAh Pack above - which equates to 10,000Ah at 3.2V, or in the context of a 12.8V Lithium
Battery - 2,500Ah. - so that £12 power pack is like buying 25 100Ah Lithium Batteries at around £300 each. Result
But I happened this morning to watch this video from bigclivedotcom tearing one down. Should be an interesting revelation even for those who buy into the listings? Oh, this on is a puny 9 MILLION mAh pack, not a bigger 10 MILLION mAh one like yours .....
For those who don't want to watch the video but just get the conclusions on this kind of crap ....
forget the specs - this is what they can really do and often have (or don't have!) (plus some comments from viewers)
- Cannot deliver more that 1.5A without voltage plunging.
- Actually delivers 2400mAh (which in 12V battery context is 0.6Ah - a little different to the thousands of Ah claimed)
- Half the space is taken up by a lump of metal instead of a bigger battery - to give the buyer that reassuring 'heavy so must be good' feeling.
- Solar panel is often fake and a piece of printed plastic.
- Even if these units do have real solar panels, do NOT leave them in direct sunlight as it may overheat them and cause the lithium cell to fail dramatically.
- one commentator ... "A friend of mine bought a "1,200mAh power bank that delivered maybe 250mAh. I opened it up and discovered that 3 of the 4 18650s inside were filled with sand"
Posting this as too many see a product like this at that kind of price and think they are getting a bargain. No, they are getting a delivery of crap in the post.
Maybe an actual video showing what a lot of these packs REALLY contain might help?
(got a good name though for those who are not hungry
)
