350w Solar Generator With 98800mah Power Storage

People & Blogs

Introduction

Hey guys, welcome back! This is Bill, the expat prepper living in the Philippines. It has been quite a while since I've done a product review on any kind of solar generator. I own around half a dozen different brands, ranging from 150 watts to 600 watts, including Blue Eddies and some generic knockoff ones.

Recently, I came across an amazing deal for a Koi 350-watt DC solar generator, priced at around $ 70 USD. While this unit might be made of plastic, it boasts a quoted max of 600 watts and a sustainable 350 watts. It takes 10.5 to 15 volts DC input, using a small port labeled 'inout DC' at the back. The package includes a 110/220 DC charger. This device can also charge via solar panels if you have the right connection.

The lack of a USB-C port is a bit of a downside, but it does feature two standard USB ports, arriving with an 80% charge out of the box. It also comes with two 12V DC outputs and a 220V output.

To test it out, I charged it fully—though the discrepancy between showing 100% while plugged in and dropping to 92% when unplugged suggests some quality control issues. I hooked it up to a 220V fan set on high and started my tests.

Testing Phase

  1. Initial Test: The fan ran for one hour, drawing power from 92% down to 41%. Another hour brought it down to zero, meaning it lasted somewhere between an hour to two hours.
  2. Charging Performance: It took less than 20 minutes to recharge from 80% to 100% when plugged into a 220V wall socket.

While this may seem short, it is consistent with my experiences with other small units, like my Blue Eddi ones. Given the small case size and high draw of the fan, the performance is adequate.

Pros and Cons

  • Pros: Inexpensive, portable, ability to charge via DC (solar ready), multiple outlets.
  • Cons: Short runtime for high-draw appliances, minor quality control issues.

My overall verdict? For around $ 72, this little device packs a decent punch. It's not meant for long-term high-usage but for smaller, essential tasks, it works well and is highly portable.

Final Thoughts

Would I recommend it? Absolutely, for anyone looking for budget-friendly, smaller solar generators. If you have a bit more to spend, higher-capacity units like Blue Eddi may be more suited for heavy usage.
