Is your PowerPack portable charger not holding as much charge as it used to? It could be because after many cycles of charging and recharging, the lithium-polymer or lithium-ion batteries inside are getting worn out. You may want to get rid of your charger and get a new one. But simply throwing it away in the garbage with your other trash would be a serious mistake. If the charger is damaged or put under significant heat or pressure, there could be a risk of explosion or fire.
To safely dispose of your charger or any electronic device with lithium-ion rechargeable batteries, the best way is to find a recycling drop-off center nearest to you.
