Description
The SENFLY T38 is a 1600A jump starter with a built-in 150PSI tire inflator designed for high-frequency professional use — repair shops, roadside assistance, and small fleets. Its 20000mAh (74Wh) battery delivers up to 48 jump starts per charge across engines up to 8.0L gas or 6.0L diesel, while the foldable handle and HD large screen make it practical to carry and read all day, every day.
Designed for Shops, Not Just Glove Boxes
A consumer jump starter gets used twice a year. The T38 is built for the shop that uses it twice an hour. The 74Wh high-discharge pack holds enough energy for a full day of service calls, and both USB-A and USB-C outputs let technicians charge devices from whichever cable is in hand.
Carry It, Read It, Work It
The foldable handle turns a 225×125×75mm unit into a one-hand carry between bays. The HD large screen shows preset and real-time pressure at a glance — set anywhere from 3 to 150 PSI, in PSI, kPa, or bar — and the pump stops itself at the target. No crouching, no squinting, no over-inflation comebacks.
Safety That Survives Rookie Mistakes
In a busy shop, anyone might grab the booster. Patented 10-in-1 smart clamps eliminate spark and reverse-polarity risk, and the two-step start — clamp on, then start — needs no training. If something is connected wrong, the unit alarms instead of failing.

FAQ
Q: Can the T38 handle daily use in a repair shop?
A: That is exactly what it is sized for. The 74Wh battery supports up to 48 jump starts per charge, the 25mm-cylinder inflator runs a 0–35 PSI fill in 4.5 minutes, and the foldable handle is made for constant carry between bays.
Q: How is the T38 different from the T39?
A: Same 1600A class, different priorities. The T38 maximizes battery capacity (74Wh standard, 88.8Wh optional), screen readability, and carry convenience for professional daily duty. The T39 prioritizes thermal performance with the Turbo Cooling Max triple-fan system. We can quote both for comparison.
Q: Does it work on diesel trucks?
A: It starts diesel engines up to 6.0L and gasoline engines up to 8.0L — covering light trucks, vans, and most service vehicles. For 24V heavy trucks, see our T40.
Q: What customization is available for tool distributors?
A: Color, logo, packaging, labels, and manuals are standard. Four battery capacities (37–88.8Wh) let you build tiered SKUs, and full ODM tooling is available for exclusive designs.
1. How do I determine what specifications of product I need?
First, confirm the engine displacement of your or your main customer group's vehicles. Generally, higher displacement vehicles require a larger starting current, and battery capacity is positively correlated with starting current. Also, note that lithium batteries experience reduced activity in cold environments; therefore, in cold regions, even for small-displacement vehicles, it's best to use a larger capacity starting power supply.
2. Why do some manufacturers offer significantly larger battery capacities and starting currents for the same product size?
You need to know that current global battery technology still prioritizes energy density in relation to battery volume and weight. If the product you receive has an abnormally high peak current or capacity, be aware that it may be fraudulent. We are committed to providing genuine and high-quality products to our customers; this is our bottom line.
3. What kind of after-sales policy do we offer?
We offer two different after-sales policies to suit your needs: 1. We provide a certain percentage of extra products with each order for you to replace your customers' products; 2. We offer a 1-2 year after-sales guarantee. During this period, you need to collect the damaged products and send them back to the factory for our technicians to assess. If the damage is not caused by human error, we will resend the products with your next order.
4. What can I customize for the products?
We offer rich and flexible customization services. For standard product versions, you can choose battery capacity, product color, logo printing, customized outer packaging, cable clip specifications, customized product specification labels, and instruction manuals. If you need a more competitive product, you can choose a full ODM service. We provide free appearance design and 3D modeling. You only need to pay an additional mold fee to have your own custom molded product.
5. What certifications do our products support?
Our products can support almost any certification you need, such as: CE, FCC, 3C, UKCA, UL, PSE, BIS, RoHS, UN38.3, MSDS, TÜV, etc.
