Pisugar Portable Power Module with 1200 mAh Lithium Battery for Raspberry Pi-Zero Power Supply, Board Kit W/WH Model Accessories (Not Include Raspberry Pi) (1200 mAh)

This is a brilliant little "all in one" battery for Raspberry Pi projects, you don't even need solder, you can power just by pressing it (there are small plastic screws included to attach) to the bottom of the pi. It lets you charge while using, use as a totally wireless device, has an on-off switch (press for on, double press for off) and 4 leds that indicate battery charge level.Mine took about 4 weeks to arrive as I think the unit comes from China, but apart from that, no issues at all.

That the board is the same form factor as the pi zero is really nice, and the connectors transferring power without a cable is cool. Generally really nice and happy. Delivery was much quicker than advertised too, which was handy. Downsides though are that the battery life is not great, so seems better suited to a UPS role than running remote from a power socket. The battery is held on to the board by a magnet which seems flexible in theory but actually with the short wires seems more of a gimmick and the longevity of the wired connection concerns me though I've not had any actual issues. Access to the switch is fiddly. I purchased version 1 on reading reviews reporting quality issues with version 2, and I see there is a version 3 on it's way. The issue here for me, is that the distinction between the versions is not clear on github.

Il prodotto sarebbe dovuto arrivare tra il 29 luglio e l’11 Agosto, invece è arrivato oggi, 7 luglio...con larghissimo anticipo e mia grande sorpresa. La confezione si presenta utile, in quanto la scatola di plastica è semplice ma ben fatta e resistente. Al suo interno, rinchiusa in una confezione di quelle tipiche dei prodotti elettronici, si trova la batteria e la scheda che permette di agganciarla ad un qualsiasi raspberry (nel mio caso) tramite la gpio, permettendo così di dare corrente a tutto. Un pulsantino permette di sapere la carica residua della batteria ed una porta mini usb permette la ricarica con un comunissimo cavo ed un caricatore qualsiasi.Devo ancora testarla per bene, ma credo che sia buona...sicuramente è piccola e adatta ad alimentare progetti che occupano poco spazio. Non posso fornire informazioni sulla durata perché ancora la devo testare, ma credo che non sia poca...poi dipenderà dall’uso che ne viene fatto e dalla complessità del progetto.
