Jackery Portable Charger User Guide

Works fine. I wish this came with a user's guide, though.

The design and controls were intuitive for me to use so I won't be needing to keep checking the user guide.

Especially good when working after dark or when hiking. But it could use a better user's guide.

Another impressive product from Godox. Without consulting the user-guide I was up and running in minutes after charging the battery pack. Godox claim remarkably fast cycling times between discharges, and from what I have experienced the strobe lives up to it's spec. For the performance and duration, it is impressively small, light and portable, and competes with comparable strobes nearly twice the price. It feels well constructed and durable. I have invested in a Godox system and so far I have not been disappointed.

This book was a valuable investment with my new camera. Gets you going faster than the Nikon User Guide and the index is valuable in finding details of D3500 features quickly. He gets you going and adds layers of experience as you use the camera and progress through sections of the book. Well worth the cost for a companion helper with a foundation of years of Nikon experience.

I reviewed a 1500VA UPS unit earlier after purchasing it last summer for my work-at-home workstation. It is still working fine. When the UPS's were offered again on B&H's daily Deal Zone, I purchased three additional units - (1) 1500 VA and (2) 500VA. As I commented earlier, the packaging does NOT come with an Installer/User Guide, but it is available online and a MUST-HAVE. I proceeded to charge the units for 24 hours prior to adding the intended devices for UPS/surge protection. The next day, the alarm sounded on one of the 500 VA units, and it displayed Error Code E06. The User Manual identified the Error Code as, Battery Charge Failure - Turn-off the UPS and call Vertiv technical support for a replacement unit. I emailed Vertiv and their Customer Service representative responded immediately and walked me through the replacement process. Vertiv replaced the unit under warranty and provided a shipping label for returning the defective unit. Vertiv's customer service is outstanding, just like B&H's. I previously gave this 4-stars because of the lacking User Guide, but that has been forgiven. All four of my Vertiv Liebert UPS units are functioning satisfactorily.

Fairly new to photography and I took the plunge and bought a Canon R6 because I wanted to buy something nice and not work my way up. This user guide is perfect for someone who is starting up or even for a seasoned photographer. I showed this book to a friend who was my go to for canon questions and he was presently surprised by what he saw, he himself started looking for a guide for his R. It's compact, user friendly, not complicated like most user manuals and very insightful. The breakdowns with picture examples are the best part. If you are on the fence trust me it's worth it.

Easy to use so far pics are very good. Very lightweight but feels good not cheap. Only complaint user guide only on line

This really helps to make the Gemini more portable and user friendly ....would recommend ....

Great product so far, works well with the Jackery panels I already had, I like the app too
