Two things caught my attention with this USB power bank, being sold in a UK shop called Poundstretchers. The low price and unusually large size for its capacity.
Inside it's actually quite neat, and very hackable if you want to add larger capacity 18650 cells.

Geez! That's nearly the size of my 5000 mAh powerbank! Or looks like it
We live in a world where writing real capacity on the box is "suprising"
I got one it burmt my finger and i think poundland should check them with the manfacurers and take your back to pounland
I have a single cell version of this in the DIY format where I add my own 18650. I bought 2 for a little under $1 each. They were garbage. One was defective and the blue full charge indicator came on when I attached a cell and just stayed on. Neither boosted the output to 5V; you just got cell voltage out. The charging circuit seemed to work OK. But the quiescent current was 790 microamps!
I did get a refund since they were defective. Too bad, because, like you said, the plastic cases are actually quite well made. They support the pcb and USB connectors very well.
I have a power bank similar to that exept it has better cells it's 4900 mah
Just bought a similar looking 1200maH unit from 99p Camden high street..charging it now..nervous
I like the honest capacity. Most of the sellers would just call it 50 000 mAh or so :).
I looked in poundstretchers by me, they don't sell them now.
old cell technology. i have sony 18650 cells with capacity around 2400mah. With this i can build 4800mah powerbank. Neat.
got a DIY one that allows 5 cells in (unprotected cells only) and it's about as uselsss as a single cell charger. My Nexus 7 literally doesn't charge when it goes to 3 of the 4 lights Goes down 1 light and bang nothing. Says charging like 9 hours later but it's actually gone down in capacity ๐ (Banggood) Don't think it's the cells. I can get a better charge from a 4 cell DIY metal housing (ha) one. also Banggood
Hi The hole for led as not bin drilled again seems to be a lot like that i got one with no hole i put in hole and i can see the led now.
+bigclivedotcom , I had one of those until I had issues.ย New excuse for missing homework, "My Battery Pack Burned My Homework".ย Caught fire after 4 uses.
I got this product from ebay for 2$ each, except my model didn't include batteries. I put in my own samsung 18650's, for about 5000mah of power that I use to recharge my drone batteries in the field. Works AMAZINGLY! I highly recommend them! Oh and it charges from a cell phone charger if you like.
I have a 20,000 mAh powerbank that contains 2 10,000 cells. Only cost me 40 bucks CAD. It's made by Aukey so it's legit.
You can get the case/ circuit board assembly on ebay without the batteries really cheap (diy power bank). Also, you can get just the circuit board for about $1.
