I’ve bought a few Baseus USB products (charger and cables) and so far only had good experiences. I used to buy Anker but the reviews on their latest products indicate too many QC issues for the premium that they charge.
Lots of bad ratings. Most with the same issue. Though this is not unusual for these high power chargers. I haven’t found any 100 watt chargers (including Anker) that don’t have a bunch of bad reviews. Especially longevity. Way too many , “2 months and it died” type reviews.
I want one, but I think I will wait to see if they ever improve the chip (switching) and reliability.
Thanks for taking the time to explore your suspicions. So the control board likely controls the BMS. I took another look and still couldn’t find online pics of this particular pack.
It looks like the sale has ended and BLF cleared them all out.
I bought these 3 for $14.99 they have a switch instead of button the switch is off, on and movement sensor that turns off after 20 seconds. I find them easier to use for old folks.
I have some under a different brand name. Like the light, but the battery is short lived in high use areas. That seems to be common in lights this size and design, whether LiOn powered or AAA. Just not much juice available.
I use them for places where you don’t use them much, like the pantry and towel cabinet, the pantry light gets recharged once a month when I start noticing the light not being bright enough. the towel cabinet about every 2 months. Not bad IMO.
Of the 8 packs I tore down, 1 of them contained dead cells measuring around 0.5V
Attempting to recharge lithium cells that have been stored with voltage this low is a safety hazard and must be recycled. Hopefully everyone checks the voltage of their cells before putting them into service.
The rest of the cells measured around 3.25 –3.29V and are just fine.
