I may have a faulty one but my SuperCheap 17Ah jump pack wont hold a charge for more than 2 hours. Used mine last night to power my EQ6 and couldnt understand why all my photos came out like the scope was jumping around all the pix was blurry and elongated. Changed over to a 40Amp swith mode and everything came good. Checked the voltage on the jump pack and it was down to 9volts. Put the battery on charge over night removed charger this am and the battery was still at 9 volts. Will check the charger tonight.
