If you often go camping, hiking, or spend time outdoors with limited access to power outlets, a solar power bank can be a reliable backup for keeping your devices charged. Like a regular power bank, it can be charged through a cable, but it also uses solar energy to provide emergency power when outlets are unavailable.
In this guide, we’ll cover the key factors to consider before buying a solar power bank, from battery capacity and charging speed to durability and extra features. We also rounded up 9 powerful solar power banks available on Lazada and Shopee to help you stay prepared during outdoor trips and unexpected blackouts

How to Choose a Solar Power Bank - Buying Guide
Solar panel size, output wattage, and battery capacity are some of the top features you need to consider when shopping for a solar power bank. In the buying guide below, learn how such features matter and what could be the best baseline as your starting point.
Check the Solar Panel Size and Charging Efficiency
A power bank’s built-in solar panel is usually designed for emergency backup rather than fully recharging the battery quickly. If you plan to rely more on solar power during outdoor trips, choose a model with a larger panel or multi-panel design to capture more sunlight.
For better reliability, look for a solar power bank that also supports fast USB-C charging, allowing you to recharge it quickly at home before heading outdoors. This ensures you still have a dependable power source even when sunlight is limited or weather conditions change.
Prioritize Power Banks with Higher Output Wattage for Faster Charging
Beyond getting power into your power bank via solar, you also need to look at how quickly it transfers energy out to your devices. Pay close attention to the output wattage rating: higher numbers mean significantly faster charging times for your smartphone or tablet. Look specifically for protocols like USB Power Delivery (PD) or Quick Charge (QC), as these verified standards ensure the power bank can actually deliver high-speed charging to compatible devices.
Avoid listings that make vague claims like "rapid charge" without providing an exact wattage figure or recognized standard. Without concrete technical specifications, you run the risk of buying a device with sluggish charging speeds.
Choose Battery Capacity of at Least 10,000 mAh
For occasional use or very short trips, a 10,000mAh solar power bank already does the job. It's good for roughly 2 full smartphone charges plus a few top-ups for earbuds or fitness trackers, and light enough to toss into a bag without adding bulk. The trade-off: solar charging alone can take around 25 hours in direct sunlight, so it works best as a backup rather than your only charging method.
On the other hand, for weekend camping or multi-day travel, you’re better off getting a unit with 20,000mAh to 25,000mAh battery capacity for the ultimate peace of mind. But expect a bulkier unit and around 50 hours for a full solar recharge, so pair it with USB charging when you can.
Opt for Units with 2-4 Ports for Simultaneous Charging
More ports mean you can charge multiple devices at once, which is useful if you're traveling with a group or you have various devices to charge. Look for a mix of USB-A and USB-C, so you're not stuck needing an adapter.
Before buying, check whether the listed output wattage is a shared total or available per port. This detail affects how fast each device actually charges when more than one is plugged in. For instance, a "20W" power bank splitting that across two ports charges noticeably slower than one that delivers 20W to each.
Choose Compact and Lightweight Designs for Portability
A solar power bank should be easy to carry, especially for hiking, camping, or travel. Heavier models with larger batteries may provide more power but can add bulk to your bag. Check the product dimensions and weight before buying, especially if you plan to carry it daily.
For outdoor use, also consider the build quality and protection features. Look for models with a clear IP rating instead of vague waterproof claims. An IP65 rating protects against dust and light water splashes, while IP67 or higher offers better protection for wetter environments.

Frequently Asked Questions
Are Solar Power Banks Allowed on Airplanes?
Yes, solar power banks are generally allowed on Philippine flights, but they must follow airline rules for lithium-ion batteries.
- Carry-on only: Power banks are not allowed in checked baggage
- Capacity limit: Most airlines, including Philippine Airlines and Cebu Pacific, allow power banks up to 100 Wh in hand luggage
- Quantity limit: Usually up to two power banks within the allowed capacity
- Safety: Keep terminals covered, avoid damaged units, and ensure the capacity label is visible
Always check your airline’s latest guidelines before flying, as rules may vary.
How Long Do Solar Power Banks Last?
Most solar power banks use lithium-ion or lithium polymer batteries, which typically last for up to 500 charge cycles or about two to three years with regular use. The solar panels, meanwhile, are built to last longer, up to over 10 years in ideal conditions, but their efficiency may degrade over time.
Among recommendations to keep your solar power bank well-maintained is to avoid overcharging. It should also be stored properly and cleaned regularly.
How Are Solar Power Banks Charged?
Solar power banks can be charged in two ways:
- Solar charging: Built-in solar panels convert sunlight into energy. This method is useful for emergencies or outdoor trips but is usually slower than wired charging
- USB charging: Most models can also be charged through a wall adapter, laptop, or other power source, which is faster and more reliable for everyday use
For the best performance, fully charge the power bank via USB before trips, then use solar charging as a backup when you have access to sunlight.
Ensure Your Devices Are Charged Whenever, Wherever
It sure is a bummer whenever devices are low on batteries, especially in times of need. We’ve listed some recommendations for other power banks you may find useful for your needs, as well as cables to pair them with or with your solar power bank.
