Rockpals was nice enough to send me their newly designed 500W li-ion battery pack, the PS500.
This new design has a much curvier look than their previous 500W model. It is a budget price for the capacity of 505Wh.
- [Fast Charging Technology] -Durable solar power portable generator that takes only 3 hours to have 0%~80% when using 72W DC and 45W USB-C PD to charge at the same time. A very reliable solar generator for home use or when you're in a hurry to go camping or other outdoor activities. Its charging time will drastically cut down your time to wait. Go ahead your journey with our amazing portable generators for camping. Your need is our first priority.
While I like the ergonomics and price point of the PS500 – it still can’t match my favorite for this size of power station: The Ecoflow River 600. That is my favorite mid-size power station because it charges so dang fast.
The Rockpals has a standard charging time, taking in around 68W from the AC charger when charge level was at 75%. This is a similar charging speed to most power stations. The Jackery 300 recently added the ability to charge with two inputs, A/C and USB-C power. But that is two cords to add 60-70% more charging speed…handy, but still not as convenient as Ecoflow’s speed.
But, back to the Rockpal. Compared to the previous 500W model, the aesthetics are dramatically better. Take a look at this older ugly box model:
- [Massive Capacity]: The ROCKPALS 500W power station provides 505Wh (140,400mAh) of energy, enough juice to power all kinds of electronics as camping gear for your next great adventure. It can fully charge an iPhone 12 about 50 times, a 12’’MacBook about 9 times, a drone (60Wh) about 7 times. It can power a camera for about 20hrs, a fan (20W) for about 18hrs, a mini car refrigerator (40W) for about 10 hrs, and a projector (60W) for about 7hrs.
Unboxing the Rockpals 500W PS500
I unboxed the Rockpals PS500, while out in central Oregon on vacation, from the back of my truck. The unit is quite light and compact for its capacity size, which is a huge plus. I could see myself putting this in the back of my car for road trips or just everyday use if I am out to the river or working from a coffee shop and want to make sure I can keep all my devices charged.
Features of the ROCKPALS PS500 I Like
1. Ergonomics
I like the overall weight and feel of this battery pack a lot.
2. Price
At $.67 per Wh of capacity, this is a good choice if you need cheap capacity
Features of the ROCKPALS PS500 I Don’t Like
1. Charging Speed
The PS500 charges at around 70W in from the AC wall charger. This is half the Ecoflow River 600 speed.
2. Low USB-C output (only 45W)
Only 1 USB-C and its just 45W output. Not nearly close to the 100W of the Ecoflow River or 60W of the Jackery 300 or Nitecore NES 300.
Overall review
If I could find a good deal and needed a 500Wh range battery pack, and didn’t care about quick charging or need more than a 45W USB-c – this is a good pick. The ergonomics of the ROCKPALS PS500 are great, and its a solid budget pick in this capacity size range. At around $0.67 per Wh of capacity, this is definitely a good value in terms of capacity. Most Li-ion battery packs in this range are usually closer to the $1 per Wh capacity wise. That number continues to fall.
