Frequently Asked Questions
Q: Do batteries come included with the KEBIDUMEI 18650 power bank case?
A: No, batteries are not included. You will need to supply 6 × 18650 flat-top lithium batteries. For best results and safety, use batteries of the same brand and same capacity — never mix different brands or capacities.
Q: What type of charger do I need to recharge this power bank shell?
A: You need a USB-C cable and a fast-charge adapter rated at 5V/3A or higher. An EU-standard compliant adapter is recommended for safe and efficient charging.
Q: Why won't the power bank work immediately after I install the batteries?
