The Olala 10,500 battery bank is a 2 port portable charger that supports Quick Charge 3.0 output. I’ve owned many battery banks over the years and this stands out because of one killer feature: quick charge. It can make a significant difference in charging speed if your phone supports it. iPhones, might not notice the difference, Androids that support Qualcomm Quick Charge will see the biggest difference. The battery bank is wrapped in metal and has a fairly substantial weight to it. It requires a press of the power button to output charge, it will not automatically start charging with a USB cable plugged in. I used a voltage/amperage tester with this one to measure capacity, current, speed, etc. and the charger had a stable voltage while charging and an 83% efficiency (about average). One thing I wish it had though is quick charge for charging itself – seems silly that it recharges a lot slower than it charges other devices. Since it supports QC output it should support QC input too. It charges itself a little slower than some other battery banks I’ve used – expect about 7 – 10 hours for it to fully recharge itself. Overall, if you want a quick charge battery bank the build and style of this one is pretty nice and its charge speed is consistently quick.
Summary: While it’s nice to have the solar panel as a last-resort type backup, it does not do much, so consider this product as its value as a regular charger before purchasing. When left on my window sill for days in direct sunlight, I was only able to get this charger up to about 25%. This is better than nothing, but solar will not be your primary charging source with this battery.
- Can start a car many times without needing to be recharged
- Bright light for emergencies
- High-speed (2.1A) charging for mobile phones
- Excellent build quality
- Includes a plastic case
- A USB hub is needed to charge multiple USB devices at once
Conclusion: The 1byone portable car jumpstarter is something I keep in my car for peace of mind. It’s saved me on multiple occasions now as I was having battery troubles with my vehicle (it turned out one of the battery poles had cracked and now that it is replaced the car is fine again). It has the capability to jumpstart most vehicles many times – after the engine is started, it will recharge itself. I’ve had it in my car for a year now and I haven’t had to take it out and recharge it, and it’s worked every time I’ve needed it. The build quality is good and the case it includes is nice too. It’s great to have the USB port for emergency phone power too, but I wish there was two ports. Often I find myself needing to charge two devices at once. Overall, I would highly recommend keeping a jumpstarter kit in the car, and this has done the trick for me.
