I was introduced to Airborne Technologies products (which is widely known for their powerbanks) when they had their launch last year. Right now, they have currently a buy 1 take 1 promo on some of their featured promos.
Those featured products are the AT Tough Rock 11,200 mAh powerbank (1), AT Arsenal 24,000 mAh laptop powerbank (2) at Php 9,490, AT Boombox speaker (3) at Php 1,800 and their slim 12,000 mAh powerbank (4) at Php 3,700
As I checked their Facebook page, no official info on until when they will have this offer. Those who are interested to buy can go to www.airbornetech.com.ph
