Capacity & intended use

The ViewSonic S1008D is a 38800mAh portable power bank designed for outdoor activities such as camping and hiking. Its orange, weatherproof housing includes sealed port covers for water and dust resistance. A built-in solar panel provides supplemental recharging when mains power is unavailable. Dual LED flashlights with steady, SOS and strobe modes add emergency lighting.

Compatibility check

Verify that your devices charge via USB Type-A or USB Type-C at 5V/2.4A maximum. The power bank delivers up to 2.4A from a single port or splits current across three simultaneous outputs. Solar recharging depends on sunlight intensity and is slow; a wall adapter via the Micro USB input is required for a full initial charge of at least six hours. Ensure you can accommodate the 5.9in x 2.95in x 0.98in dimensions in your pack.

Build integration

The unit weighs 280g and includes a hook and carabiner for attaching to a backpack, leaving hands free while the solar panel tops up the battery. Three output ports let you power a phone, tablet and another device together, reducing the need for multiple chargers. Smart LED indicators show green for solar input and blue for USB input so you can monitor charging status at a glance.

Questions about this item

Does the box include a wall charger or only the Micro USB cable shown in the photos?

The package supplies a Micro USB cable for wall recharging; a separate USB wall adapter is required to plug into mains power.

Should I pick the 38800 mAh orange model or is there a different capacity in the same range?

This listing is the single 38800 mAh orange variant; no other capacity or colour is offered for the S1008D.

How many full phone charges can I expect from the 38800 mAh rating in daily use?

Real-world output is lower than the rated 38800 mAh due to conversion losses; typical smartphones receive roughly two to three full charges before the power bank needs recharging.
