Aukey Pby37 Manual ~upd~ -

I couldn’t find an official Aukey PB-Y37 manual in my current database — but I can still help you understand the device and locate the guide.

First, let’s clarify the model number:
Aukey’s power bank model numbers are often like PB-Y37 (which would be a portable battery pack). Based on typical Aukey power banks, the PB-Y37 likely has:

  • 20,000mAh capacity (or 10,000mAh)
  • USB-C input/output
  • USB-A outputs
  • LED power indicators
  • Supported fast charging (Power Delivery, Quick Charge)

🔋 Charging the PB-Y37

  • Use a USB-C to USB-C or USB-A to USB-C cable.
  • Input power: likely 5V/3A, 9V/2A (supports 18W fast charging input).
  • Fully charges in 4–6 hours depending on charger.

Part 8: Is the PBY37 still relevant? (Manual vs. Modern Power Banks)

If you are searching for the Aukey PBY37 manual because you are considering buying this model (perhaps used or old stock), here is the reality check.

Pros:

  • Huge 20,000mAh capacity (6-7 full iPhone charges).
  • Two inputs (Micro-USB & USB-C) – great for cable compatibility.
  • Durable plastic shell.
  • Low-current mode for wearables.

Cons:

  • No fast charging (No Qualcomm Quick Charge, No Power Delivery (PD)). It outputs only 5V.
  • USB-C is input only (can’t charge newer USB-C laptops or iPhones with a C-to-C cable).
  • 5-7 hour recharge time is slow by 2025-2026 standards.

Verdict: The PBY37 is a solid "slow and steady" emergency battery. If you need speed, buy a newer model. If you need a reliable, simple backup for travel, the PBY37 is great.

Part 3: How to Charge the Aukey PBY37

The PBY37 is unique because it has two ways to get power in. Your physical manual likely shows a diagram of this. aukey pby37 manual

Method A: Micro-USB Input

  • Use the included cable (or any high-quality Micro-USB cable).
  • Connect to a USB wall adapter (5V/2A recommended).
  • Charging time: 6–7 hours.

Method B: USB-C Input

  • Use a USB-C to USB-A cable (C end into PBY37, A end into charger).
  • Supports faster charging (5V/2.4A).
  • Charging time: 5–6 hours.

Important Note from the Manual: Do not plug a USB-C to USB-C cable into the PBY37’s input port if the other end is connected to a laptop. The PBY37’s USB-C port is input only. It will not charge a laptop or act as a USB-C output. I couldn’t find an official Aukey PB-Y37 manual

While charging:

  • LEDs will blink sequentially (chasing lights).
  • When fully charged, all 4 LEDs remain solid. Unplug immediately to preserve battery health.

4. Powering On & Pairing

Automatic Power On/Pairing:

  • Open the charging case lid. The earbuds will power on automatically and enter pairing mode.
  • On your device (phone/tablet), go to Bluetooth settings.
  • Look for "AUKEY EP-T31" (or similar PBY37 designation) and select it to pair.

Manual Power On (if earbuds are out of the case): 🔋 Charging the PB-Y37

  • Touch and hold the touch panel on both earbuds for 3 seconds until the LED flashes blue.
