Chinese While preparing for a Mount Rinjani trek, travellers often focus on physical training and the steep summit climb. What they often forget is their electronic gear during a 3D2N trek. A key essential is a portable power bank to keep devices running throughout the journey.
The weather on Mount Rinjani is harsh for modern electronics. As you move from humid rainforests to the freezing Sembalun Crater Rim, conditions change quickly. Cold temperatures at higher elevations can significantly reduce lithium-ion battery performance and shorten usable battery life. There are no charging stations as you climb higher. A dead phone or camera can stop you from capturing the scenery or sunrise. This is the last thing you want on your trek.
This article is for those preparing for a Mount Rinjani trek. It offers guidance on choosing a reliable backup power source, and also recommends some of the best brands. It highlights key factors to help you make the right choice. Make sure you read this article to the end.
Which portable power bank is the best for trekking?
The Nitecore NB10000 Gen III is widely regarded as one of the best power banks for trekking due to its lightweight design and reliable performance. However, it is not the only option to consider. It depends on the types of gadgets you use. Some devices need more charging capacity. Others may not require a high mAh power bank.
Apart from simply focusing on the brands, the most important qualities that you should focus on are the high power-to-weight ratio, fast charging capabilities, and strong environmental protection against dust and freezing temperatures. Below are the recommendations for power banks based on the number of hours you spend during the trek:
Ultralight and Short Treks (1-2 days)
These treks are meant to be very light, just for quick overnight stays without wasting packing spaces. The best option here is the Flextail Zero Power Bank with a capacity of 10,000 mAh and a weight of 114 g. Its lightweight design makes it a practical choice for trekking, including use in colder mountain environments. It also has an IPX4 splash rating and a USB fast-charging port. It also fits very sleekly in a backpack without adding any bulk and keeps the smartphones and headlamps safely powered.
The other best option is the Nitecore Carbo 10000 Power Bank, weighing 157 grams. This device is highly puncture-resistant and explicitly impact-tested against hazards during the trek. It also has a feature of low-current trickle charging mode that can safely charge small devices such as smartwatches and earbuds without causing any damage to them.
Multi-Day Hikes for Multiple devices (3-4 Days)
For a three to four-day hike, you will need a portable power bank with a slightly bigger capacity since you will be travelling for a couple of days. There is also a possibility that you might need to charge multiple devices throughout the trek. The products that dominate for these treks are the Anker 325 Power Bank and the Goal Zero Venture 75. The Anker provides a 20,000 mAh capacity, allowing multiple recharges for smartphones and other devices during a multi-day trek. It also has an inbuilt Power IQ technology that prevents overcharging for the devices.
On the other hand, the Goal Zero Venture is an ultimate, sleek, but pure device for survival on treks. It also has an IP67 dustproof and waterproof rating, which allows it to survive the worst drops in mud, rivers, or ash. The dual ports present are equally efficient, and they can charge two devices at the same time.
5+ days trekking expeditions
For long-haul journeys, every mAh of battery matters. This is especially important if you plan to create content or go on an all-in adventure. If your devices use a lot of power, consider the Biolite Charge 100 Max. It is built for long expeditions. It's 25,000 mAh capacity stores a large amount of energy. It can power devices such as laptops, camera equipment, and drone battery charging systems during extended expeditions.
Another important distinction here to note is the presence of sub-zero alpine resilience. Its design helps maintain reliable performance in challenging outdoor conditions, although battery efficiency may still decrease in extreme cold. It also has wireless charging. A multi-port layout lets you charge multiple devices at the same time.
3 Pro-Tips to Save Your Battery on the Mountain
Even though you might have a portable power bank, it is important to know and practice smart battery conservation. What people do is they often tend to neglect small habits that can eventually help them to be safer, even in case they run out of battery in their power banks. Below are the 3 pro-tips to save your battery during your Mount Rinjani trek:
Keep your devices warm - Extreme cold on the summit of the mountain often slows down the chemical reactions inside the lithium-ion batteries, which cause the power to drop very quickly. Keep your phone and power bank inside your sleeping bag or in an insulated pocket close to your body during cold nights.
Activate airplane mode constantly - Since there is almost zero signal across most of the rainforest, if the phone is left on normal settings, it will drain battery trying to search for a signal. Therefore, it is best to keep the device on airplane mode purely for capturing photos. However, use airplane mode whenever you do not need mobile connectivity to reduce battery consumption.
Optimise your settings before you start hiking - Make sure you optimise your phone completely before beginning the hike. Reduce screen brightness, disable unnecessary connectivity features, and close background applications before starting the hike.
