The suitcase of every professional working person who needs to stay in touch with their company and their home must include a power bank. As promotional items, power banks are very effective, given that they travel far with their owners and carry your logo along with them as a very classy business card.
2000 Mah Solar Power Bank is even better than most of the power banks usually used, since its battery is rechargeable on solar energy, due to the solar cells. Of course, it can be also charged via standard USB cable, which is also included.
The 3-in-1 CU5999 cable is usable on all devices with mini or micro USB ports and IPhone 4/4S. 5V/1A DC input/output bank includes power and charge indicators. ABS and aluminum product comes in 2” W x 4” H x 0.25” D dimensions with an additional wrist strip, which makes it always at hand. The power bank is individually packed, with instructions included.
