Tronsmart Presto Is A Slim, Quick-Charging Battery Pack That's Qualcomm Compliant
Tronsmart's Presto stands out from the hundreds of portable chargers on the market because not only is it Qualcomm certified -- Tronsmart's website actually has a copy of the certification to prove it -- it also has a bi-directional USB-C port, meaning you can charge the Presto with USB-C, or charge something else with that same cable. There's also a traditional USB outlet, so this is effectively a dual-port charger.
At 12,000 mAH, the Presto has enough power to charge the typical Android smartphone three to four times. And if you're concerned about fire, Tronsmart says the Presto has 11S circuit protection, which includes input/output overvoltage protection and temperature protection.
Oh, and for what it's worth, Tronsmart sources its battery from ATL, the same company that provided the "good" batch of batteries to the Note 7s (a source within Samsung told the WSJ it was SDI that supplied the potentially explosive batteries).
The Tronsmart Presto retails on Amazon for about $30.
