Frequently Asked Questions (FAQ):

Q1: How do I choose between the DLP-X81 and DLP-X82?
A1: Choose the DLP-X81 (1-Slot) if you need a single battery backup for one device. Choose the DLP-X82 (2-Slot) if you frequently use multiple high-power devices at once, allowing you to charge two batteries simultaneously for seamless rotation.

Q2: What power source do I need to use this charger?
A2: The DLP-X81/X82 is powered via a standard USB port (5V 2A input). You can connect it to any standard USB wall adapter, laptop USB port, power bank, or car USB charger using a regular USB cable.

Q3: Does this charger support 18650 batteries as well?
A3: Yes! The spring-loaded sliding slots on the DLP-X81/X82 are universally designed to safely charge almost all cylindrical 3.6V/3.7V Li-ion batteries, including 26650, 18650, 21700, 18500, 18350, 16340, and 10440 sizes.

Q4: How do I know when the battery is fully charged?
