    Does Not Come With Plug

    You really need the right charger or “plug” to correctly charge this battery. A 30w charger or “plug” component does just fine. Without it? It will not show the charging symbol and will take hours upon hours to charge.

    I understand that it was sent a 0% power because it is a lithium battery but I was worried that it took a long time to move from the 0% spot and then over a day to charge

    The 30w input is why it takes a very long time to recharge.

    This charger is way too big to be carrying around. Not worth the purchase if you're going to travel with it. Look for something more compact.
