I don’t know about TOMO, never had one, so I’ll just share my experience with the 4*18650 powerbanks that I have used.
Soshine E3S: It melted on the first weekend I over-used it (charge->discharge non stop). And started smelling… And stopped working…
Epilot E4: Has survived without a hiccup for two weekends until now, same use, charge -> discharge -> repeat for the most part of each day.
I would buy Epilot again, but not Soshine.
