Setting Up Your Solar Charger

For reliable UK power, always use mains charging as your primary method, with solar as a backup or for emergencies. Follow these steps:

1. Initial Charge (Essential)

  • First use: Fully charge your power bank via mains (Type-C cable included).
  • Duration: Charging time depends on battery size. Example: a 20,000mAh bank may take 6–8 hours; a 30,000mAh bank may take 8–10 hours; larger banks will take longer.
  • LED indicator: Shows charging progress.

2. Solar Panel Positioning

  • Best angle: In the UK, tilt the panel at 30–40° in spring/autumn, and flatter (10–20°) in summer when the sun is higher.
  • Panel direction: Always face the panel directly towards the sun for best results.
  • Panel size matters: Larger panels (e.g. 6–8W folding panels) will charge much faster than small built-in panels (1–2W).

3. Estimating Solar Charging Time

  • Solar panel output: A typical built-in panel (1–2W, ~200–400mA) may add 1,000–2,000mAh per sunny summer day.
  • Folding panels: A 6–8W folding panel can add 3,000–4,000mAh per day in strong sun.
  • Calculation: Daily mAh added ≈ panel current (mA) × hours of direct sun. For example, a 400mA panel × 5 hours = 2,000mAh.
  • Battery size: Divide your battery capacity by the daily solar input to estimate full charge time. (e.g. 20,000mAh ÷ 2,000mAh/day = 10 days in sun)

UK Charging Recommendations

Spring/Summer Use

  • Solar works best April–August, especially on clear days.
  • 6–8 hours of direct sunlight needed for meaningful charge.
  • Keep panel clean from pollen, dust, or bird droppings.
  • Expect 1,000–4,000mAh per day depending on panel size and sun strength.

Autumn/Winter Use

  • Rely on mains charging October–February.
  • Solar may only maintain charge, not increase it, due to low sun and short days.
  • Store indoors if temperatures drop below 0°C.

Solar Charging & Glass – What You Need to Know

  • Direct sunlight is essential: For best results, place your charger outside, facing the sun. Avoid charging through glass or plastic covers.
  • Behind glass (car or indoors): Car windows and home glazing can block 50–70% of solar energy. Charging speed will drop sharply, and may not work at all on cloudy days.
  • Why? Modern car glass is designed to filter UV and reduce heat, which also greatly reduces the type of sunlight your charger needs.
  • Tip: If you must use solar in a car, place the power bank as close to the glass as possible on a sun-facing dashboard. Expect much slower charging.

Fact: Solar charging behind most car windows is typically only 20–40% as effective as outdoors. For fastest solar charging, always use direct, unobstructed sunlight.

Maintenance Tips

  • Panel care: Wipe clean with a microfiber cloth weekly.
  • Mains priority: Charge fully before trips (solar is backup).
  • Storage: Keep 50% charged if unused for months.
  • Temperature caution: Avoid leaving your power bank in hot cars or freezing conditions.

Example: A 2W built-in panel may add up to 1,500mAh per sunny summer day. An 8W folding panel can add up to 4,000mAh per day in strong sun. Actual results depend on weather, panel angle, and location.

How Your Power Bank Works

This hybrid charger combines solar and mains charging for reliable power anywhere. Below we explain how it works for all models, including those with built-in and folding solar panels.

1. Dual Charging Methods

  • Solar Charging: Converts sunlight into power. Built-in panels are typically 1–2W (200–400mA); folding panels may be 6–8W (1200–1600mA).
  • Mains Charging: Fast charging via Type-C, Micro USB, or Lightning (model dependent).
  • Wireless Charging: Some models support Qi wireless charging for compatible phones (see product details).
  • The power bank automatically uses the fastest available charging source.

2. Power Storage

  • High-capacity lithium battery (e.g. 20,000–46,000mAh, varies by model).
  • Stores energy from solar or mains for later use.
  • Long standby: Holds charge for up to 3–4 months when unused.

3. Device Charging

  • Multiple outputs: Dual USB-A, Type-C, and sometimes wireless (see your model).
  • Fast charging: Up to 2.4A per port (model dependent).
  • Auto-detects and adjusts for your device’s needs.

Solar Performance & Optimization

  • Panel angle: For best results in the UK, tilt the panel at 30–40° in spring/autumn, and flatter (10–20°) in summer when the sun is higher.
  • Panel size matters: Built-in panels (1–2W) may add 1,000–2,000mAh per sunny day; folding panels (6–8W) can add 3,000–4,000mAh per day.
  • Estimate your charge: Daily mAh added ≈ panel current (mA) × hours of direct sun. Example: 400mA × 5 hours = 2,000mAh.
  • Battery size: Divide your battery capacity by daily solar input to estimate full charge time. (e.g. 20,000mAh ÷ 2,000mAh/day = 10 days in sun)
  • Glass warning: Charging behind car or house glass can reduce solar input by 50–70%. For best results, use outdoors in direct sunlight.

Example: A 2W built-in panel may add up to 1,500mAh per sunny summer day. An 8W folding panel can add up to 4,000mAh per day in strong sun. Actual results depend on weather, panel angle, and location.

Pro Tips for Best Performance

  • Initial charge: Fully charge via mains before first use. Charging time depends on battery size (e.g. 20,000mAh: 6–8 hours; 30,000mAh: 8–10 hours; larger banks take longer).
  • Solar charging: Works best in direct, unobstructed sunlight. Clean the panel regularly for maximum efficiency.
  • Panel angle: Adjust the tilt for the season—flatter in summer, steeper in spring/autumn.
  • Storage: Recharge every 3–4 months if unused. Store at 50% charge for long-term storage.
  • Temperature: Avoid charging or storing in extreme heat or cold (e.g. hot cars, freezing conditions).
  • Expectations: Solar is for backup or emergency use. Mains charging is always faster and more reliable.

Example: A 2W built-in panel may add up to 1,500mAh per sunny summer day. An 8W folding panel can add up to 4,000mAh per day in strong sun. Actual results depend on weather, panel angle, and location.
