Lord Nityananda has all the power of Lord Krishna

nityananda prasade se haya visnu-bhakti
janiha-krsnera nityananda purna-sakti

"By Lord Nityananda's mercy one attains devotion to Lord Vishnu (Krishna). Please know that Lord Nityananda has all the power of Lord Krishna."
Chaitanya Bhagavata Madhya 12.26

It is important to notice that Lord Nityananda is described in this verse with words purna-sakti. Purna means full, complete, and sakti means power. So we must understand that Lord Nityananda has all the powers of Lord Krsna. That includes all His transcendental qualities like Name, Form, Pastimes, Abode etc. Just like Lord Krsna is non-different from His own Name, on the same way Lord Nityananda is identical with His own Name. This verse indicate to this highest truth. Janiha krsnera nityananda purna-sakti. Lord Nityananda has all the power of Lord Krishna.
