30000mAh high-capacity power bank

The RETMSR YD-887B packs a 30000mAh lithium-polymer cell rated at 3.7 volts. It delivers roughly 10 full charges for an iPhone 8, 7 charges for an iPhone 12, 6 charges for a Galaxy S9 and 3 charges for a Pad Mini 5. The unit also powers tablets, headphones, cameras, desk fans, hand warmers and gaming consoles.

22.5W USB-A and 20W USB-C fast charging

Three USB-A ports share a 22.5W maximum output and a 20W Power Delivery USB-C port handles both input and output. Four devices can charge at once, with a Galaxy S9 reaching full capacity in about 40 minutes. Dual 18W Micro-USB and 20W Type-C inputs refill the bank in roughly 6 hours using a 20W adapter.

Pocket-sized 6.77 x 3.43 x 1.0 inch design

At 1.03 lb the bank fits in a pocket or bag without adding bulk. Built-in safeguards include over-charge protection, auto shut-off and short-circuit protection. A scratch-resistant finish and LED indicator lights add durability and status visibility, while an integrated flashlight covers emergency or low-light needs.

Questions about this item

Can the YD-887B charge my older Micro-USB phone and a USB-C tablet at the same time?

Yes, it has three USB-A ports and one USB-C port, so you can connect up to four devices simultaneously using the cables you already own.

How do I confirm the 22.5W fast charge is active on my Galaxy S9?

The phone will show its fast-charging animation and reach a full charge in about 40 minutes when plugged into a USB-A port.

Does the box include a 20W wall charger for the 6-hour recharge?

No, only the power bank and a charging cable are supplied; a 20W adapter must be purchased separately to hit the 6-hour refill time.
