All-in-One Charger with Built-In Cables

The charmast W1115 integrates a foldable AC plug, USB-C cable, Micro-USB cable and a Lightning cable into a 10000mAh lithium-polymer power bank. It delivers a stable 15W output at 5V and 3A for phones and tablets without extra accessories. The compact purple unit measures 5.95 by 2.76 by 0.72 inches and weighs 8 ounces.

Replaces Separate Power Bank.

This single device removes the need to carry a standalone charger, multiple cords and a bulky power bank when travelling. The jump is worth it if you want one item that recharges itself from a wall socket in seconds and then powers your devices through built-in cables. CE and FCC certifications confirm safe operation.

Check Your Devices Use USB-C, Micro-USB or Lightning

Verify that the gadgets you intend to charge match the three integrated connectors before ordering. The power bank itself recharges only through the foldable AC plug, so a wall outlet must be available. It is not suited for users who need higher wattage, wireless charging or additional port types.

Questions about this item

What are the exact dimensions of the W1115 power bank?

The unit measures 5.95 in x 2.76 in x 0.72 in and weighs 8 oz, fitting easily in a jeans pocket with 40% less bulk than standard banks with separate cables.

How do I recharge the power bank itself, and what step is often missed?

Unfold the built-in AC plug and insert it directly into a wall outlet; the step users miss is pressing the power button to confirm the recharge has started.

When will the built-in cables need replacement?

The reinforced cable joints are tested for thousands of bends and rated 3X more durable than standard cables, so replacement is rarely needed during the unit's lifespan.
