This is the best portable charger out there right now, and you can even get a great price on it online. Good. Incredibly large battery (23,000mAh) will charge your phone, table, or even your laptop. Can charge 3 devices at one time.
The battery pack is 4x AA NiMH tab-type cells, glued together in a 2x2 square, 116g. Nominal capacity is 4.8 V and 2000 mAh (nominal 9.6 W-h). For charger compatability it should be replaced only with NiMH cells, not NiCd or Lithium-Ion. I did not trace the circuitry enough to know if the charge smarts lie with the PCB or the charger and thus do not know if a different charger could be used.
