42800mAh solar power bank

The Mregb YD-819 is a high-capacity portable charger with a 42800mAh lithium-polymer battery. It features integrated solar panels for supplementary recharging and a built-in super bright LED flashlight. The rugged ABS housing provides IP67-rated waterproof, dust-proof and drop-proof protection for outdoor use.

Suits off-grid users; not for minimalists

This unit suits campers, hikers and emergency-prep buyers who need multi-day power and a durable flashlight that can run for up to 100 hours. It also fits households wanting a single backup station for several phones. Buyers who want a slim pocket-sized charger for daily commuting should look at something else.

USB-C input and output with QC 3.0

The USB-C port handles both input and output, while two USB-A outputs support QC 3.0 fast charging at 5V 3.1A for compatible devices. Three devices can charge simultaneously. The single specification that decides fit is whether you need USB-C two-way operation combined with rugged outdoor durability.

Questions about this item

How many full phone charges can the 42800mAh capacity deliver in practice?

A 42800mAh lithium-polymer pack typically yields about two to three full charges for a modern smartphone, depending on the phone's own battery size and the efficiency of the USB-C output.

What does the USB-C port's 5V 3.1A QC 3.0 rating actually limit?

The USB-C port handles both input and output at up to 5V 3.1A with QC 3.0, so charging speed is capped at that voltage and current for any connected device.

Will the IP67-rated case fit in a standard rucksack pocket?

The rugged ABS shell is built to IP67 waterproof, dust-proof and drop-proof standards, so it slides into most rucksack pockets without extra bulk.
