You want a more portable option: Because of its combo nature, the Anker 733 is a bit bulky and cumbersome, but if you use it both ways, it''s worth the trade-off in size to have such a useful device.
Battery protection circuits for the most demanding applications are operated mostly by Integrated Circuits (ICs) typically using MOSFETs to switch lithium cells in and out of circuit. The over-current protection is normally provided when the IC detects the upper current limit of the battery being reached and then interrupts the circuit.
The PCB is a management system that works for digital batteries. Examples of these small battery packs include the mobile phone battery, GPS batteries, Music player batteries, …
