I really should have tested the solar panel while I was making the video. I just tested it, and under my bright bench lights it puts out a miserable 4mA when I would have expected something closer to more than 100mA for that cell size.

The 18650 lithium cell has a capacity of 745mAh and upgrading it is made difficult by the fact that the unit has been sealed shut by gluing the glass on the front with silicone sealant.

While being functional, this unit is engineered to the edge for cost, and would at the very least need a different solar panel if the one supplied was useless like this one was.

The four charge status LEDs looked promising, but have been faked. They're just two pairs of LEDs in parallel. So you basically get 50% and 100% if that.

I can give you a link to this light, but don't pay more than about £6 and treat it as a project.

$AliExpress unbagging joy with fake lego and hotel stuff - VOLUME ALERT! Another Santa-sack of technical goodies from AliExpress for us to explore. Here are some links to the items on AliExpress (not a sponsor). These are affiliate links, but that will not affect the price you pay. Keep in mind that these products may not meet your countrys standards. Single ended cut to length LED filament:- https://s.click.aliexpress.com/e/_c4kBOIiV Cost about £1. Solar car light thing:- https://s.click.aliexpress.com/e/_c4l9Bnod Cost about £2. Fake lego portaloo portable toilet. This is apparently referred to as an MOC (My Own Creation) and is generally more fun that official models, and a tiny fraction of the price:- https://www.aliexpress.com/item/1005004572701012.html Cost about £3. Real lego has a slightly dark history. https://en.wikipedia.org/wiki/Hilary_Page Water level sensor module (Ive not explored it yet.):- https://s.click.aliexpress.com/e/_c3KSo6FX Cost about £2. UVC toilet steriliser. Ive made the video - its totally fake, but will make your toilet look very futuristic:- https://s.click.aliexpress.com/e/_c2z6dZPL Cost about £3. The intriguing glass vehicle bulbs that I tested in arcade buttons:- https://s.click.aliexpress.com/e/_c3RUv0cD Cost about £2 for a pair. Im about to order a blue version of this bulb so we can see the construction with the bare chips. High voltage module:- https://s.click.aliexpress.com/e/_c30656qV Cost about £2. As mentioned in the video the quoted output voltage is fake. Sharp electrodes will spark at around 1kV per mm due to ionisation. NEVER operate these modules with the output wires more than 20mm apart, as the high open circuit voltage can destroy the internal circuitry. Pimple hydrocolloid patches:- https://s.click.aliexpress.com/e/_c4NdiUch Cost about £1.20 for loads. German parking timer disk that cheats:- https://www.aliexpress.com/item/1005008806388282.html Cost about £3. Hotel grade programmable 500ml capacity oil diffuser for creating a controlled ambient aroma:- https://s.click.aliexpress.com/e/_c3UaFpAZ Cost about £30. I also got some Weston hotel white tea aroma oil and even on the lowest setting this unit is far too powerful for a small home. The place experiences explosive bursts of intense bergamot aroma. You can buy small USB rechargeable home aroma units for just a few pounds, and bottles of their own aromas for about £2 that can be refilled with something of your own choice. Note that thicker essential oils can be watered down with very light volatile mineral oil. Larger venturi units are used by theme parks to give a characteristic aroma to themed attractions. They are terrible to refill and maintain because you end up getting the aroma oils on your hands and clothing.

The 100 and 200 LED sets come with a USB plug and the longer sets come with a plug-in power adapter (with a European plug). It does say 220-240V on the adapter, but I tested it on 110V and they lit.

It does have a micro SD card slot and can either charge, be used as a camera or appear as a drive when plugged into a USB port:- https://s.click.aliexpress.com/e/_c3InSQF7 Note that this appeared in the bundle deal section at a lower cost, so shop around.
