Which Powerbank ?

MouldyOldDough

I have decided to follow the governments advice and purchase a decent sized Powerbank

However - The 60,000 mAh one that I am interested in - may not actually be a 60,000mAh model - wonder what you lot thought ? https://amzn.eu/d/08gdi6Wd

And what size should I go for ? My phone has a 5,000mAh battery and lasts several days , my tablet has a 20,000mAh battery !

I am not buying anything over 26800mAh due to restriction of flight.

Solar powerbank may be an option for that emergency purpose? Although i don't know if those small solar panel actually work…

I was looking at these too - the panels included are generally way too small to actually charge the battery in a realistic time period. Flight doesnt affect me - I stay in UK

I do wonder, especially with these Chinese brand-you've-never-heard-of powerbanks, how you would ever know if the capacity was anywhere near what was claimed in the Amazon listing or on the box. At least with dodgy storage devices you can test them to verify they're dodgy.

20,000mAh battery in a tablet? Something specialised/ruggedised?

I would stick to Anker or Ugreen. An iPad only has c8500 maH , must be a big tablet.

Agreed - Anker and Ugreen are the most credible brands - we have owned 4 or 5 Anker power banks , always work well (the ones with the built in cables are my new favourite, my wife likes the mini 5000mah that sits at the bottom instead of attaching to the back.).

A tablet with a 20,000mah battery is insane, I'd imagine specialised outdoor ones that are big, bulky and weigh a ton? Certainly not the typical.

I don't buy more than 20,000 just for the simple reason they start getting too big and bulky (unless you get the Chinese specials that are allegedly hundreds of thousands mah and unbelievably the size of a usb stick). My main one is 10,000 which fits in the palm of my hand.

I consume about 3600mah on my phone a day (I have a foldable phone so my tablet rarely gets used). A 20,000mah power bank would last me about 5.5 days, 10,000 is about 3. I can't recall a time I've been without power for more than 24 hours (my power bank is mainly used to charge my earphones that stay in my gym bag).

A dodgy storage device will usually be programmed to show the promised storage capacity, which the OS would display in File Explorer so would fool most people.

What usually happens to get around data being copied onto it is the firmware has an overwriting loop, so at say 16gb (the drives actual capacity) it would start overwriting itself instead of throwing an error and making the user aware.

To identify this the user would need to have the foresight to run a bespoke testing tool to find out the true working capacity or run integrity checks on all their files. A simple test could just fill the drives up with several large video files and then see if they all play.

A fake power bank is even simpler. If I buy a power bank that purports to be 50,000mah and my phone is 5,000 I should be able to charge my phone to full about 10 times. If the power bank dies after 4 charges, I know I've been had.

That said I'd heavily recommend not buying no-name dubious Chinese power banks as they can catch fire.

I have an Anker 20,000 mAh power bank. It works well. It’s a big heavy lump. I wouldn’t consider a larger size.

Not quite what you're looking for but I've just bought a Bluetti Elite 100 V2. Mine was from eBay not Amazon, but was still from the official UK distributor.

1024Wh (which is roughly 275,000mAh, if anyone was foolish enough to measure it that way) with USB-A, -C, 12v and 230v outputs.

It'll run my portable split heat pump for a couple of hours (I tried it this evening), will handle a 1000W travel kettle, or my rice cooker, or my George Foreman grill.

I bought it for 2027s summer camping trips but it'll also work for the Government's 72-hour preparations.

That or a Jakery if you were that worried about a blackout
