Using a Power Bank to Revive a Vintage 1930s Bus: Essential Buying Tips

Power banks are becoming increasingly powerful, packing remarkable energy capabilities into compact devices. They have evolved from simply charging smartphones and tablets to even jump-starting vehicles.

Typically, these portable jump starters are intended for regular cars and trucks. However, I decided to push the limits and try starting a 1936 Albion SP PV70 coach. This classic vehicle is part of a vintage collection in North Wales, UK, and yes, it remains drivable to this day!

The GT6000 model represents the pinnacle of portable power banks, with a 27,000mAh/99.9Wh battery. It's capable of powering devices through a 100W USB-C port, an 18W USB-A port, a 12W USB-A port, and a 150W DC output. Remarkably, using a 100W USB-C charger, it can charge from empty to 20% in just seven minutes, achieving a full charge in under 90 minutes.

Notably, this unit can retain its charge for nearly two years, making it a reliable emergency backup if stashed in your car.

Now, let's talk about the Albion—a sizeable, cozy coach.

The GT6000 can deliver an 800A starting current and a peak current of 6,000A to the jump leads. This power suffices for most gasoline engines and diesel engines up to a whopping 12 liters. Although the six-liter engine of the Albion is relatively modest, it's elderly and hefty, and the coach's battery was entirely depleted.

The device sports a 3.2-inch LED display, providing crucial data like battery life, charge and discharge rates, and readiness for jump-starting vehicles. The matte screen is easily readable in bright daylight as well as in dim light.

How did it perform? The GT6000 accomplished its task effortlessly, proving its effectiveness. For evidence of this remarkable performance, check out the accompanying video.

In terms of longevity and resilience, the GT6000 is impressively sturdy, able to withstand rough handling. It boasts an IP65 rating for dust and waterproofing, meaning it's completely dust-tight and can endure rain and splashes. Additionally, it features a built-in LED light, proving useful in case of night-time emergencies.

Its durability means you can place it carelessly on the ground without concern.

I'm genuinely amazed by the prowess of this device. It melds a formidable power bank with an efficient jump starter. After experimenting with various vehicles, the speed and dependability at which it revived the decades-old Albion astonished me. Its capacity to deliver high current reliably was truly commendable—even assisting the bus during several restarts along its journey when it happened to stall!

This has unquestionably earned a spot in my garage toolkit.
