Tableta a fost alimentata gresit si s-a dus partea de incarcare, i-am scos integratul care facea acest lucru, fiind in scurt, si as vrea sa-i pun o rezistenta de limitare sa pot sa o folosesc. Tableta functioneaza fara probleme. Alimentatorul are 5V 2A iar acumulatorul 3,7V 1,1A, ar fi indicat mai degraba sa pun doua diode in serie pentru limita tensiunea la 3.8V?Este exclus sa pun alt integrat, fiind o chinezarie nu avea nimic inscriptionat pe el!

Tableta functioneaza bine-mersi si alimentata doar prin USB, fara baterie. Are convertoare peste tot, procele merge undeva la 1.2 sau 1.8v, I/O si uneori LCD sau touch la 3.3v, memoriile la 2.5, 1.8, 1.5 depinzand de tehnologie. Nimic nu ruleaza direct din baterie intr-un asemenea dispozitiv. Nu e nicio problema atat timp cat nu depasesti 5 volti.
