Telah dilakukan penelitian tentang inovasi pembuatan Gama Powerbatik, power bank murah berbasis baterai isi ulang Ni-MH (nikel metal hidrida). Baterai Ni-MH dipilih karena secara konsep memiliki kesesuaian nilai tegangan yang dapat menghantarkan arus ke baterai gadget, serta dapat pula menerima hantaran arus dari adaptor 5 V. Penelitian menggunakan metode kuantitatif eksperimen, dengan pelaksanaan sejak awal Desember 2013 hingga Juni 2014. Spesifikasi Gama Powerbatik yang berhasil dibuat memiliki dimensi 65 60 20 mm dengan tegangan output ( ) rerata 4,82 4,84 V, arus output ( ) antara 200-300 mA, dengan 5 varian kapasitas ( ): 1.900, 2.300, 2.700, 2.800 dan 4.700 mAh, serta dilengkapi label produk bercorak batik untuk setiap varian kapasitas. Hasil analisis harga power bank di pasaran dapat disimpulkan bahwa biaya produksi Gama Powerbatik tergolong murah dan berpotensi untuk dipasarkan, terutama produk berkapasitas 2.700, 2.800 dan 4.700 mAh.

The research about cheap power bank innovation based Ni-MH (nickel metal hydride) rechargeable batteries named Gama Powerbatik has been done since December, 2013, until June, 2014. Ni-MH battery was chosen because of value of its voltage between 3.7 and 5 V, so it could transferred current to gadget and also received current from adaptor. The spesifications of Gama Powerbatik are described as following: dimension 65 60 20 mm, average output voltage ( ) 4.82-4.84 V, output current ( ) between 200-300 mA, variant capacity ( ): 1,900; 2,300; 2,700; 2,800 and 4,700 mAh, also it�¢ï¿½ï¿½s labeled with various batik pattern for every capacity. Its inexpensive price make these products have a good market potential, especially for capacities of 2,700; 2,800 and 4,700 mAh.
