How to Use Solar Power Bank

As with new mobile phones, it is advisable to USB charge the product completely for at least 6 hours (or overnight), before first time use. Follow the power bank solar charger user manual below to charge your power bank using solar power or USB & AC adaptors directly. After charging, plug in your phone and press the power button to turn on the power bank. Your phone will start charging as normal. The power bank will auto switch off when your phone battery is fully charged. Or if the power bank is depleted unless the solar panel is exposed to the sun. To switch power bank off manually, press the power button again.

Before you go on a trip with your solar power bank, it is important to charge your power bank using any of the methods below.  If your model has a LED flashlight, how to turn on power bank flashlight depends on the model but the the action to take is similar. Press the power button 2-3 times in quick succession; or depending on model, press and hold the button for a few seconds to turn the flashlight on or off.

How Many Times Will My Power Bank Charge My Phone?

How many times a power bank will charge your phone from zero % can be determined by dividing the power bank’s battery capacity (mAh) by that of your phone's battery capacity. Note that all power banks lose about 15% power due to various reasons like aging (natural chemical degradation at a constant rate over time), heat generated by the power bank, climatic conditions, internal control circuit voltage regulation and ability of your phone to charge its battery, etc. This means that if your power bank is 10000 mAh, the actual capacity you will get is 8500 mAh. This can be difficult to calculate exactly but it is safe to follow our fair guide.

At What Power Level Should I Charge My Power Bank?

There has been a lot of debate about when is best to recharge a power bank. Some argue that power banks discharge and lose power faster at low percentage power than when full. Therefore if you charge your phone at low power level, it won’t transfer all the charge into your phone. Others suggest that lithium batteries degrade/age faster when fully charged (100%) than at lower levels of charge. As a result, many say it is best to keep your power bank at 50% to 80% charge level.

Our practical test results show that your power bank should give you optimal performance for about 1.5 years. Refer to our blog on 500 life cycles. This is the minimum you should expect from a top quality brand. Your HG power bank will continue to serve you well for 2 to 3 years and beyond depending on how you use it. But expect to charge it more frequently as it gets older.

Our suggestion is that based on your need to keep your phone charged up as many times as possible, this is practically best achieved if your power bank is fully charged. So, take every opportunity to charge it up. The embedded solar panel will automatically begin to recharge the power bank on exposure to light and will continue to do that for as long as there is light.


Charging a Solar Power Bank Using Electricity

HetoGrow solar bullet  Plug your power bank into USB charger using a wall outlet or to a computer using a USB cord. The LED indicators will dazzle with flashing lights to indicate that the power bank is charging.

HetoGrow solar bullet  The LED indicators will come on with blue flashing lights, or green light, depending on model, when exposed to the sun or when charging with with a USB cord. The flashing indicators will vary as the charging progressively completes. How long to charge power bank for depends on capacity. Charging with electricity/USB takes about 6-12 hours depending on the model.  The result you get depends on whether or not the phone being charged is switched on or off. Phones consume energy to remain on, hence will take longer to charge up. Note that the solar panel mainly provides emergency backup and the main priority is to recharge the power bank on exposure to sunlight. It takes about 40 – 90 minutes to fast charge a smartphone, using the HG power bank usb cord, depending on the phone.  Other USB cords may not be as fast but if you must use other brand USB cords, ensure they are at least USB 2.0.


How to Charge a Phone with a Power Bank 

HetoGrow solar bullet When charging your mobile phone or other electronic devices, first connect to the power bank with USB cable. Press the power button once to start charging. The LED indicators of flashing blue light will turn off progressively till the power bank is fully discharged into your gadget. A fully charged power bank can charge a smartphone (2000mah - 2500 mAh battery) 2 - 5 times depending on model (4000mAh to 10000 mAh HetoGrow power bank); and phone type. 

HetoGrow solar bullet  Note that the solar panel provides emergency backup power as it continually recharges the power bank on exposure to sunlight. This is the standard inbuilt priority. Consequently, when using a solar power bank to recharge your phone during the day, which is the secondary protocol, ensure you keep the solar panel away from the sun or cover the solar panel. This ensures that the primary function reverts to charging your phone and also ensures fast charge.

HetoGrow solar bullet  Note that when the solar panels are exposed to the sun, depending on the model, you will see a green light (first/one bar only) or flashing blue lights. To check the power/charge level, press the power button once and observe the progressive blue lights which indicate level of power stored. If your model comes with a digital reader, it will show percentage (%) of power stored.



How to Charge Solar Power Bank Using Solar Power

How long to charge a solar power bank depends on the capacity. To charge your power bank using the solar panel is easy and quick depending on the quality of sunlight you have. Solar charging will be very fast on bright sunny days and slow on cloudy days when the brightness of the sun is not good. It is pertinent to note other factors that can affect the performance of the solar panel such as direct exposure to the sun and angle of contact, size or surface area of the solar panels, temperature, battery size and frequency of usage. The implication is that it can take longer to charge a solar power bank using the solar panel. The larger the solar panel, the faster it can charge and the shorter the time. How long it takes to charge a solar power bank depends on many other factors but charging with solar panel can take about 15 to 17 hours of optimal solar power.  It can take longer depending on capacity and exposure to sunlight.

Photovoltaic (PV) devices are predominantly measured under standard test conditions. Industry-wide standard test conditions (STC) are used to assess power rating and performance of Photovoltaic (PV) modules (assembly of connected photovoltaic solar cell packs). Tests are performed at solar cell temperature of 25°C and an irradiance (solar exposure) of 1kW/m2 with an air mass 1.5 (AM1.5) spectrum. This is equivalent to a clear sunny day with solar panel tilted to 37° and the sun at an angle of 41.81° above the horizon. This ideal industry test standard ensures ease of product comparison. However, in real life conditions are never perfect. For best performance, we suggest that you ensure solar panel(s) face the sun directly with no obstructions.

The solar pv is ideal as backup power source in the absence of regular electricity supply. For best results, the user should:

HetoGrow solar bullet  Find a safe and bright spot outside with strong direct sunlight. Avoid obstacles including glass. 

HetoGrow solar bullet  Position your HG solar power bank in a way that ensures the solar panel is facing up directly toward the sun 

HetoGrow solar bullet  Ensure there is adequate ventilation to avoid overheating

HetoGrow solar bullet  Monitor the LED light bulbs that indicate the level of power stored in the power bank.
