seem like a good product at first . as a portable , the suction be adequate . I use it 3 or 4 time a month to vacum my small car . after use it yesterday , I plug it in to recharge , and it will not charge . do not know if the ac adapter be bad or the battery be bad . I do not get my money worth from this vacuum . I give up with the battery power unit . I be look for a a ac power hand vac with more suction .
